2.0 INTRODUCTION

Nobis Engineering, Inc. (Nobis) has prepared this Interim Remedial Action (RA) Completion 

report to summarize the results of construction and response activities conducted at the 

Eastland Woolen Mill (EWM) Superfund Site (the Site), Operable Unit I (OUI), located in 

Corinna, Maine. 

Nobis conducted this work for the U.S. Environmental Protection Agency (EPA) under contract 

to U.S. Army Corps of Engineers (USACE) New England District through Remedial Action 

Contract No. DACA33-03-D-005, Task Order 0001. 

2.1 Site Background

2.1.1 Site Description

The Site is located in the center of the Town of Corinna, Penobscot County, Maine, 

approximately 6 miles north of Newport and 25 miles northwest of Bangor, Maine (Figure 1). 

The Town of Corinna is located within the East Branch of the Sebasticook River (EBSR) 

watershed. Elevations within the immediate vicinity of Corinna range from 200 to 320 feet above 

mean sea level (msl). 

2.1.2 Site Operational History

The Site was formerly dominated by the EWM building complex which, before its demolition in 

2000, was comprised of a large manufacturing building and several ancillary structures, with a 

total area of 250,000 square feet. The buildings stood on both sides of and over the EBSR, a 

State-designated Class C water, which flows north to south through the center of Corinna 

(Figure 2, Figure 3). 

Prior to closing in 1996, EWM was a manufacturer and finisher of wool and blended woven 

fabric. Fabric finishing included dyeing of the fabric to meet product or customer requirements. 

This dying operation took place in dye kettles and utilized various chemicals, including dyes and 

dye-aids that reportedly contained biphenyl and chlorinated benzene compounds, including 1,2-

dichlorobenzene, 1,3-dichlorobenzene, 1,4-dichlorobenzene, and 1,2,4-trichlorobenzene. Until 

construction of the Town of Corinna Wastewater Treatment Plant (WWTP) in 1969, liquid 

wastes from the mill were discharged to the ground surface beneath mill buildings, to Mill Pond 

Dam tailrace, and ultimately the EBSR. It was not until 1977 that all liquid waste streams were 

finally directed to the WWTP. 

As a result of these discharges, overburden soil and bedrock underlying mill buildings, and river 

sediment and underlying soil extending several hundred feet downgradient were contaminated 

with chlorinated benzene compounds. Groundwater was contaminated at concentrations well 

above federal drinking water Maximum Contaminant Levels (MCLs) and State of Maine drinking 

water Maximum Exposure Guidelines (MEGs). Routine pumping of nearby residential bedrock 

wells spread the contamination laterally along bedrock bedding-plane fractures. 

2.1.3 Discovery, Investigations, and Removal Actions Leading up to NPL Listing

Groundwater contamination was first documented in Corinna in 1983, when a Maine 

Department of Environmental Protection (MEDEP) employee noticed a strange odor and taste 

in drinking water at the Gallison Restaurant located across the street from the Mill. Several 
OUI Interim-Remedial Action Report Page 5 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

water samples collected from the restaurant showed the presence of monochlorobenzene, 

dichlorobenzenes and trichlorobenzenes. Later in 1983, granular activated carbon (GAC) filters 

were installed on five supply wells (residential and business) near the Mill to mitigate exposures 

to chlorinated benzene compounds. 

EWM initiated formal environmental investigations in 1984 by performing a preliminary 

hydrogeologic investigation of the downtown area. The work included the completion of soil 

borings, installation of monitoring wells and piezometers, sampling and analysis of soil and 

groundwater and a preliminary fracture-trace analysis. The investigation concluded that 

additional work was needed to identify a contaminant source area. By 1988, EWM had 

completed a study of residences and businesses at risk from the groundwater contamination, 

and had investigated potential locations for installation of a public water supply system. It was 

concluded that contamination had likely spread via bedrock fractures and faults. Five additional 

private water supply wells were fitted with GAC filters based on results of water supply well 

sampling performed between 1983 and 1988. 

In 1993, EWM completed Phase I of a chlorinated benzene contamination investigation in the 

downtown area. The report identified the tailrace beneath the Mill and the underground storage 

tank (UST) area where dye-aid had been stored adjacent to Building 13 as possible source 

locations. 

EWM removed three USTs from the UST Area in 1994. Chlorinated benzene compounds were 

detected in soil samples collected from the bottom of the excavation. An overburden 

groundwater recovery well (R-1), consisting of a 30-inch-diameter corrugated metal pipe with 

slits in the bottom five feet and surrounded by crushed stone, was installed at the site after 

removal of the USTs, because free product was reported in the excavation and soil staining was 

observed. In addition, a drum containing a dark oil-like substance was unearthed in the UST 

excavation. Recovery Well R-1 was pumped to collect chlorinated benzene-contaminated 

groundwater and flush contaminants from the “smear” zone between August 1994 and 

sometime in 1995. In conjunction with the pumping of groundwater from Well R-1, EWM 

instituted pumping of groundwater from the bedrock well on Lot 122, south of Main Street, now 

referenced as Recovery Well R-2. 

In the fall of 1995, during the installation of water supply lines to serve contamination affected 

residences, personnel working for EWM observed excavation activities in the riverbed just 

downstream of the Main Street bridge. During this excavation, a dense non-aqueous-phase 

liquid (DNAPL) was reportedly observed within the till material beneath the gravel riverbed. The 

consultant for EWM, Acheron, Inc., performed additional sampling of the sediments in the 

riverbed downstream of the Mill and found chlorinated benzene compounds and petroleum 

hydrocarbons both within the silty till layer beneath the rocky, gravel riverbed and in a floodplain 

on the west side of the river. 

After closure of the Mill in 1996, MEDEP sampled soils around the former USTs adjacent to 

Building 13 to evaluate whether residual soil contamination was present and acting as a source 

of groundwater contamination. This effort was supplemented in 1998 with additional analytical 

parameters and sampling of a background location. In 1997, MEDEP performed sediment 

sampling with field chemical screening to gain information on the magnitude of river bottom 

contamination documented by Acheron, Inc. in 1995. Additional sediment and surface water 

samples were collected from the river in 1998 for off-site analysis. These investigations 

confirmed that high concentrations of chlorinated benzenes were present in the riverbed over 

1000 feet downstream of the mill complex. These data were used to prepare the Hazard

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

Ranking System scoring package that was submitted to EPA for placement of the Site on the 

National Priorities List (NPL). 

In 1997, MEDEP performed an emergency response action to remove 54,673 pounds of various 

hazardous substances from process pipes, containers and vessels located within the Mill. 

In addition, in January 1999, following the evaluation of data collected during an expanded site 

inspection, EPA signed an Approval Memorandum authorizing the preparation of an 

Engineering Evaluation and Cost Analysis (EE/CA) to evaluate potential response alternatives 

for a Non-Time-Critical Removal Action (NTCRA) at the Site. The EE/CA recommended 

demolishing the mill complex buildings to allow for the excavation and treatment of the 

contaminated soils on the Site. 

The Site was proposed for inclusion on the NPL on April 23, 1999 (64 Fed. Reg. 19968). It was 

listed for final inclusion on the NPL on July 22, 1999 (64 Fed. Reg. 39878-39885). 

2.1.4 Non-Time Critical Removal Action (NTCRA)

Non-Time Critical Removal Action (Soil Excavation and Treatment)

In July 1999, USEPA signed an Action Memorandum to initiate a NTCRA at the Eastland 

Woolen Mill Site. Beginning in 1999, the USEPA through USACE contracts with Roy. F. 

Weston, Inc. (Weston) performed NTCRA cleanup activities to address source area 

contamination. This NTCRA has included the removal of the mill buildings (performed during 

the winter of 1999/2000) and contaminated soils from four areas (performed from 2000-2001). 

NTCRA work areas include: 

Area 1: Region underlying Mill Buildings 1, 1A, and 3 (2001) 

Area 2: River segment down river from the mill to the abandoned railroad trestle (2000) 

Area 2a: River segment under the abandoned railroad trestle and overlapping Area 2 and 

Area 3 (2000) 

Area 3: River segment for a distance several hundred feet beyond the railroad trestle (2000) 

Area 4: Lot 88, Building 9, UST Area, and other miscellaneous areas (2000 and 2001) 

During 2000 and 2001 approximately 75,000 cubic yards (yd3

) of chlorinated-benzene 

contaminated soils were excavated and stockpiled at the Site in lined containment structures. In 

2001, pilot testing of an on-site thermal soil treatment system was performed. The results of 

this pilot test indicated that the treatment system could meet established treatment goals. Fullscale on-site treatment of contaminated soil began in October 2002 and was completed in 

October 2003. Table 1 presents the result of the treatment program. Testing of the soil after 

treatment documented that all of the soil that was used for on-site backfill contained residual 

levels of contamination below residential cleanup standards and met the NTCRA groundwater 

leaching criteria that were developed during the NTCRA. The NTCRA soil cleanup standards 

are included in Table 2 (note that the groundwater limits also shown on Table 2 are derived from 

the ROD, and were not developed to support the NTCRA). To support the NTCRA excavation 

and thermal treatment activities, a temporary groundwater extraction and treatment system 

(referred to as the groundwater management system) was constructed to aid in control of 
OUI Interim-Remedial Action Report Page 7 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

groundwater infiltration during excavation activities. One bedrock well and four overburden 

wells were connected to a temporary treatment system. The system remained operational until 

November 2004 to provide hydraulic control over the groundwater plume during the initial phase 

of the NTCRA. Specific information regarding the treatment system discharge limits is included 

in the 2004 NTCRA Completion Report, prepared by Weston (Weston, 2004). Since 2004, the 

groundwater management system has been operated as necessary to support the NTCRA insitu oxidation program. 

Details concerning the NTCRA source removals are presented in the Final Completion Report, 

Areas 2, 3, 4-Lot 88, and 4-Building 4 Soil Remediation NTCRA, Eastland Woolen Mill 

Superfund Site, Corinna, Maine (Weston, 2004). 

Non-Time Critical Removal Action – Limited Excavation and In-Situ Chemical Oxidation 

(2003-2006)

Three areas of contaminated soil were not accessible to the NTCRA excavations. One area 

was located within Area 1 and the other two were within the Area 4 UST Area and Building 14 

Area. These areas are shown in Figure 4. These remaining soils are located in the saturated 

zone between depths of 6 to 40 ft below ground surface (bgs). The final phase of the NTCRA 

targeted the reduction of contamination in these source areas using in-situ chemical oxidation 

(ISCO). EPA also retained the USACE to implement this component of the NTCRA. USACE 

retained Nobis as the lead contractor for the remaining NTCRA activities. 

An ISCO Pilot Study was performed to identify the optimal oxidant technology for use in the 

NTCRA ISCO program. In the Spring and Summer of 2004, Nobis installed 23 ISCO injector 

wells in Area 1 to depths ranging from 35 to 40 ft bgs. Following injector installations, a fieldscale pilot study was performed by a subcontractor to Nobis, Xpert Design and Diagnostics 

(XDD), and Nobis in November 2004. The pilot study was designed to evaluate effectiveness of 

two potential oxidant technologies, Fenton’s reagent and iron-catalyzed sodium persulfate 

(ICP). The Fenton’s Study Area consisted of injecting 10,000 gallons of sulfuric acid and 11,534 

gallons of hydrogen peroxide into two injection wells. The Persulfate Study Area consisted of 

injecting 5,580 gallons of persulfate and chelated Fe+2 catalyst into two injection wells. 

The results of this pilot study indicated that ICP achieved superior subsurface distribution 

relative to Fenton’s reagent due to its longer reaction half-life. Based on post-pilot study soil 

sampling, a 48% total mass reduction was estimated over the pilot study area. Based on these 

results, ICP was selected as the oxidant for full-scale treatment application for the NTCRA ISCO 

program. The NTCRA ISCO Pilot Study was also incorporated in the Remedial Design for the 

OUI ISCO program that was occurring simultaneously with the final phase of the NTCRA, and 

resulted in the selection of ICP as the oxidant technology for the OUI Remedial Action ISCO 

programs. 

The NTCRA ISCO Program consisted of two work areas: Phase I, which included the 

contaminated soil associated with the former UST Area and Building 14 Area; and Phase II, 

which included the contaminated soil associated with Area 1. These work areas are shown in 

Figure 4. 

Phase I Activities

Following demolition of Building 14 by the Town of Corinna in 2004, a limited excavation was 

undertaken by Weston adjacent to the former loading dock to remove a small quantity of 
OUI Interim-Remedial Action Report Page 8 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

contaminated soil that was present in the vadose zone adjacent to the loading dock. The 

excavation did not extend below the water table. Analytical results for confirmation soil samples 

collected from the base of the excavation indicated contaminated soil remained in-place at 

depths below the water table (approximately 6 ft bgs). 

In Spring 2005, Nobis installed 20 injector wells in the UST Area and the former Building 14 

Area to depths ranging from 15 to 30 ft bgs. ISCO treatment consisted of two full-scale 

injections of ICP, followed by confirmatory soil borings and groundwater sampling. These 

injections were performed in July and October/November 2005. A total of 13,319 gallons of 

persulfate solution (22,120 lbs of oxidant) and 13,514 gallons of chelated iron solution were 

delivered to the UST Area and Building 14 Area. Confirmatory soil borings and groundwater 

sampling indicated an approximate 90% reduction of dissolved phase contamination and an 

approximate 71% reduction in sorbed phase soil contamination following the Phase I ICP 

applications. The Phase I Task Plan and the Chemical Oxidation Phase I ISCO Work Plan 

describe in detail the activities that were performed to complete the NTCRA source reduction in 

this area. The 2005 Phase I and Phase II ISCO Remedial Performance Assessment 

documents that the ISCO has been successful in reducing the mass of contamination in the 

Phase 1 Area. The NTCRA for the Phase 1 Area is complete. The OUI Remedial Action 

includes long-term monitoring of the Phase I Area to confirm whether groundwater restoration is 

achieved. 

Phase II Activities

In August 2005, Nobis and XDD performed one full-scale round of Phase II ISCO treatment for 

Area 1. ICP was delivered to the subsurface via 11 ISCO injector wells. Approximately 19,256 

gallons of persulfate (31,947 lbs of oxidant) and 19,423 gallons of chelated iron solution (2,429 

lbs) were delivered to the Phase II treatment area. Confirmatory groundwater sampling 

performed following full-scale ISCO application indicated a reduction of dissolved phase 

contamination by approximately 63%. Soil sampling performed following the ISCO Pilot study 

indicated a 38% reduction in residual DNAPL contamination. The Phase II Task Plan and 

Phase II Full Scale ISCO Injection Plan - Application #1 describe the activities that were 

performed to further the completion of NTCRA source reduction in this area. The “2005 Phase I 

and Phase II ISCO Remedial Performance Assessment Eastland Woolen Mill Superfund Site, 

Non-Time Critical Removal Acion, Corinna, Maine, May 2006” documents that the ISCO has 

been successful in reducing the mass of contamination in the Phase II Area. The ISCO for the 

Phase II program continues as part of the OUI RA. 

The NTCRA program ended in May 2006 as documented by the Final Pollution Report 

(POLREP) for the Eastland Woolen Mill NTCRA that was finalized in September 2006. 

2.1.5 Remedial Investigation and Feasibility Study (RI/FS) 

The EWM site was divided into two operable units. From 1998 to 2002, USEPA performed a 

Remedial Investigation/Feasibility Study (RI/FS) at the EWM site. The details of the RI/FS can 

be found in the Remedial Investigation Report, Supplemental Remedial Investigation Report, 

Human Health Risk Assessment Report, Baseline Ecological Risk Assessment Report that are 

included in the Administrative Record for the OUI Record of Decision (ROD). The RI for the 

OUI Study Area identified two areas where site-related contaminants exceed federal and state 

drinking water criteria in overburden groundwater. One area is associated with the UST 

Area/Building 14 sub-area, and the other is downgradient of the former location of Buildings 1, 

1A, and 3 within the EWM complex where liquid wastes were discharged. The RI also identified 
OUI Interim-Remedial Action Report Page 9 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

an area of bedrock groundwater contamination associated with the release of contamination 

from Buildings 1, 1A, and 3 (Area 1). The major groundwater contaminants of concern (COCs) 

were determined to be benzene, chlorobenzene, 1,2-dichlorobenzene, 1,3-dichlorobenzene, 

1,4-dichlorobenzene, and 1,2,4-trichlorobenzene. The NTCRA attempted to remove the soil 

contamination that was acting as one of the major sources for the groundwater contamination. 

The OUI Remedial Action focuses on the groundwater contamination and the source material 

remaining after the NTCRA, particularly the source material in the bedrock. EPA signed a ROD 

for OUI in September 2002 and amended the OUI remedial action with a ROD Amendment that 

was signed in September 2006. 

In September 2002, EPA created OUII to address the sediment and associated floodplain areas 

of the EBSR downstream of NTCRA excavation, as well as an area of solid and liquid waste 

disposal known as the old dump. During 2002 and 2003, EPA performed a series of studies to 

better define the potential for ecological impacts in the OUII area. Surface water, sediment, 

floodplain soil, and crayfish tissue samples were collected, and biological assessments of the 

benthic macro-invertebrate community were performed. The information from these studies was 

presented in a Supplemental RI Report. The information was also combined with the initial RI 

data to prepare a revised Baseline Ecological Risk Assessment Report that found there was no 

unacceptable risk to ecological receptors in the OUII area. Both reports were released in 2004 

as part of the Administrative Record and were available for review during the public comment 

period for the OUII Proposed Plan. On September 30, 2004, EPA signed a ROD selecting No 

Further Action for OUII of the Site. EPA activities in the OUII Study Area are complete, and no 

further activities are anticipated. 

OUI is the focus of this RA report and contains the groundwater and remaining unexcavated soil 

contamination (Figure 4). 

3.0 OPERABLE UNIT I BACKGROUND

Based upon the results of the OUI FS which recommended the use of ISCO to treat residual soil 

and bedrock contamination as well as overburden and bedrock groundwater contamination, 

EPA in September 2002 signed a ROD for OUI. The OUI ROD selected a remedy which 

included hydraulic containment plus contaminant mass reduction to address groundwater 

contamination and to protect the EBSR. In the FS, several Remedial Action Objectives (RAOs) 

were developed for the site that were based upon the threats to human health and the 

environment that were identified by the RI/FS and Applicable or Relevant and Appropriate 

Requirements (ARARs). The future use plans for the site area were described in the Reuse 

Plan for Corinna Village Center, dated January 2002. In general, the future use plan for the site 

area include commercial, recreational, and residential. 

The RAOs for the 2002 OUI ROD are as follows (note that the 2002 ROD RAOs did not change 

with the amendment to the ROD in 2006): 

• Prevent the ingestion of groundwater containing contaminants that exceed Federal or 

State MCLs, Federal Non-zero MCL Goals (MCLGs) and more stringent State MEGs, or 

in their absence, an excess cancer risk of 1 x 10-6 or a hazard quotient of 1. 

• Prevent, to the extent practicable, the off-site migration of groundwater containing 

contaminants at a concentration above Site cleanup levels. 
OUI Interim-Remedial Action Report Page 10 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

• Prevent, to the extent practicable, the discharge of groundwater containing contaminants 

at a concentration above levels that could impact ecological receptors to the EBSR. 

• Restore groundwater to meet federal or state MCLs, federal non-zero MCLGs or State 

MEGs (whichever is most stringent), or in their absence, an excess cancer risk of 1 x 10-

6 or a hazard quotient of 1. 

• Perform long-term monitoring of surface water, sediments and groundwater to verify that 

the cleanup actions at the Site are protective of human health and the environment. 

To achieve the ROD-specified RAOs, the OUI remedial action includes the following major 

components: 

• Extraction and treatment of the contaminated overburden and bedrock groundwater. The 

extraction system will be designed to prevent off-site migration of contaminated 

groundwater and restore the aquifer to federal and state MCLs, federal non-zero MCLGs 

and more stringent State MEGs. This remedy component was removed as part of the 

2006 ROD Amendment (described subsequently). 

• In-situ treatment of the contaminated overburden and bedrock groundwater and 

remaining areas of contaminated soil/DNAPL. A chemical reagent (e.g., Fenton’s 

Reagent or another oxidizing agent) will be added to the overburden and bedrock aquifer 

to reduce the mass of contaminants in the system. If the mass reduction is not sufficient 

to achieve cleanup levels, then enhanced flushing (using surfactants/solvents) and 

biological degradation (using bio-stimulants) will be attempted to further reduce the mass 

of contamination. 

• Connection of certain residences to the water supply lines to prevent their wells from 

becoming contaminated, and to prevent expansion of the contamination in the 

groundwater. 

• Implementation, monitoring and maintenance of institutional controls (i.e., deed 

restrictions) in the form of groundwater use restrictions (e.g., easements or restrictive 

covenants) to prevent ingestion of groundwater and disturbance of the groundwater 

extraction and treatment system. 

• Long-term monitoring of groundwater, surface water and sediments to evaluate the 

success of the remedial action. 

• Implementation of five-year reviews to assess the protectiveness of the remedy until 

cleanup goals has been met. 

3.1 OUI Focused Feasibility Study

As part of EPA’s adaptive management of remedial actions, a Focused Feasibility Study (FFS) 

was completed for the Site in May 2006 for the purpose of reevaluating the OUI RA based upon 

the additional data collected after the signing of the ROD in September 2002. The adaptive 

management approach emphasizes the importance of using data collected during the design 

and cleanup to make better decisions about the implementation of the cleanup. 

Bedrock groundwater data collected at the Site and in the Town of Corinna between 2004 and 
OUI Interim-Remedial Action Report Page 11 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

2007 demonstrates that bedrock groundwater contaminant migration has stabilized even in the 

absence of groundwater pumping. These data also demonstrate that bedrock groundwater 

contamination is not impacting the EBSR and does not pose a current risk to the River ecology. 

These conclusions were supported by groundwater contaminant transport numerical modeling 

performed as part of the Institutional Control Zone (ICZ) development. 

These observations, coupled with the connection of residences to the local water supply system 

and the implementation of institutional controls, will greatly reduce the potential for humans to 

consume contaminated water at the Site. Based on these results, it was concluded that the Site 

RAOs could be achieved within a reasonable timeframe without long-term groundwater 

extraction and treatment. 

Additionally, the FFS also clarified that deep bedrock co-solvent flushing would not be 

implemented during deep bedrock treatments due to matrix diffusion issues that greatly reduced 

the cost-effectiveness of this technology (Nobis, 2006c). 

3.2 OUI ROD Amendment

Based upon the recommendations of the FFS, an amendment to the September 2002 OUI ROD 

was signed by EPA on September 28, 2006. The major components of the amended remedial 

action are: 

• Groundwater source mass reduction to achieve aquifer restoration 

o ISCO treatment of Area 1 deep saturated soil and shallow weathered bedrock 

o ISCO treatment of Area 1 deep fractured bedrock including installation of 

additional bedrock injection wells 

o Bio-stimulation of Area 1 deep fractured bedrock 

• Environmental monitoring 

o Groundwater monitoring to assess remedy effectiveness and progress toward 

attaining cleanup goals 

• Institutional Controls to prevent future use of the contaminated groundwater and prevent 

disturbance of the remedy 

• Connecting currently occupied properties within the institutional controls zone to the 

existing public water supply system 

• Five-year reviews to ensure that the remedy remains protective of human health and the 

environment. 

3.3 Remedial Design

The Remedial Design for the OUI Remedial Action was initiated in 2003 and completed in 

August 2005. Two components of the OUI Remedial Action were not included in the design: 

design of a long-term groundwater extraction and treatment system and the enhanced flushing 

(using surfactants or solvents) of the deep bedrock aquifer. Remedial Design was implemented 

in close coordination with the final phase of the NTCRA ISCO program since both programs 

relied on ISCO to reduce the mass of contamination in the overburden soil and bedrock. As 

such, the NTCRA design support activities and the Remedial Design support activities are 

complementary. 

A series of additional studies and investigations were performed between 2003 and 2005 to 

develop the design for the NTCRA ISCO program and the in-situ treatment portion of the OUI 

Remedial Action. The results and conclusions of these investigations are summarized in the 
OUI Interim-Remedial Action Report Page 12 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

FFS and are reported in greater detail in the Conservative Interwell Tracer Test (CITT) Design, 

Conceptual Model Update Report, and the OUI Remedial Design Report. The studies and 

investigations performed to support the design activities included: 

• ISCO Pilot Study: The ISCO Pilot Study performed for the NTCRA ISCO program was 

incorporated in the Remedial Design for the OUI ISCO program and resulted in the selection 

of ICP as the oxidant technology for the OUI Remedial Action ISCO programs. 

• Bedrock Well Installations: Fifteen bedrock boreholes were drilled in Area 1. Bedrock 

fractures were characterized by borehole geophysics, and water samples were collected by 

packer methods. Shallow fracture DNAPL distribution and rock matrix properties were 

assessed by methanol extracted rock samples (MERC). These well locations provide 

characterization data for the Area 1 bedrock groundwater and contribute to the overall 

understanding of the bedrock fracture system and its behavior under pumping conditions. 

• Hydraulic Control Pump Test: In September 2004, a multi-well pump test was initiated 

utilizing six pumping wells (EW-2, EW-3, EW-4, EW-5, EW-6, and EW-7). During the test, 

individual well flow rates were gradually increased or decreased depending on individual 

well responses. The pumping test was completed by October 2004, when the 

CITT/Electrical Resistivity Tomography (ERT) baseline was initiated. 

• Conservative Interwell Tracer Test (CITT): A CITT was designed and performed during 

October 2004 under forced gradient conditions to demonstrate that measurable flow paths 

exist within the aquifer. Data was used to evaluate dilution factors to verify the scale at 

which adequate minimum oxidant and surfactant concentrations could be maintained and to 

demonstrate sufficient aquifer connection at a scale suitable for treatment. 

• Partitioning Tracer Test (PITT): An initial PITT was designed and performed in conjunction 

with the CITT. This pilot-scale PITT was performed within the DNAPL source zone to 

assess the volume of DNAPL contacted within the swept aquifer volume. 

• Electrical Resistivity Tomography (ERT)/Induced Polarization (IP): ERT was completed prior 

to and in conjunction with the CITT to identify preferential pathways of saline solutions in the 

fracture system between individual boreholes. Selected IP profile panels were also 

completed. 

• Assessment Monitoring: Area-wide groundwater and drinking water sampling was 

implemented to evaluate and quantify the nature and extent of the overburden and bedrock 

contaminant plumes that remained after NTCRA activities. The results from the 2004 areawide sampling event are presented in the 2005 Area-Wide Groundwater Sampling Technical 

Memorandum. The results from the 2005 area-wide sampling results are presented in the 

spring 2006 Area Wide Groundwater Sampling Technical Memorandum. 

• Bedrock wells to assess aquifer characteristics: Off-site bedrock borehole installations and 

groundwater pumping tests provided refined estimates of aquifer transmissivity and 

anisotropy at locations east of the EBSR. Results are presented in the Conceptual Model 

Update Technical Memorandum. 

• Groundwater Modeling: Groundwater flow and contaminant transport numerical model 

simulations assessed the long-term impacts of the bedrock contaminant plume under 

various potential future site conditions based on varying degrees of contaminant mass 
OUI Interim-Remedial Action Report Page 13

reduction. The modeling is described in the Institutional Control Zones Groundwater 

Modeling Report. 

• Long-Term Monitoring: A Long-Term Monitoring Plan (LTMP) was developed for future 

area-wide sampling to be performed for the evaluation of plume migration and impacts. 

• Institutional Controls and Water Line Connections: The results of the area-wide sampling 

and groundwater modeling were used to identify the properties that should be connected to 

the public water supply. The results were also used to finalize the extent of the ICZ. 

The information from the studies described above was used to develop the Remedial Design 

that was approved in August 2005 and to develop the implementation work plans for the OUI 

Remedial Action. 

The OUI Remedial Action was initiated in September 2005 with the installation of the first of the 

three water line connections. All of the water line connections were completed in 2005. The 

construction phase of the OUI Remedial Action also included the installation of the injection 

system for the OUI ISCO program as well as the long-term monitoring wells. All construction 

activities for the OUI Remedial Action were completed in September 2006 as documented in the 

Preliminary Close Out Report for the Eastland Woolen Mill Site. The restrictive environmental 

covenants for the use of groundwater at the Site are still under development. 

4.0 CONSTRUCTION ACTIVITIES

This section describes the Nobis NTCRA and RA construction activities the Site; beginning with 

site mobilization in 2004 through the completion of the Phase IV bedrock ISCO pilot test in 

2007. A summary of monitoring wells, injection wells, drinking water supply wells, and 

extraction wells that have been utilized at the Site is included in Appendix C. 

4.1 Site Mobilization and Preparation

During Nobis’ initial involvement at the EWM site, Weston was on-site completing the NTCRA 

thermal desorption treatment of contaminated soil, site restoration activities, and site 

demobilization. Nobis was retained by the USACE to implement the in-situ treatment 

component of the NTCRA and the Remedial Action. 

Nobis undertook site preparation/mobilization activities for the NTCRA ISCO program in May 

2004 with the placement of approximately six inches of gravelly sand on top of treated soil that 

had been placed as backfill. This gravelly sand provided a more-stable work surface for drill 

rigs, support vehicles and equipment. 

A temporary decontamination pad large enough to allow a drill rig to back into was constructed 

using concrete blocks and removable plastic sheeting. 

Two storage containers and one office trailer were mobilized and staged at the site to provide 

storage of sampling and monitoring equipment, field consumables, and USACE inventory. 

Electrical service was later provided to the office trailer. It should be noted that at the time of 

mobilization, a Town-owned vacant house was utilized as the base of operations for USACE, 

EPA, Weston, and Nobis. In later years, after Weston had demobilized from the site, the vacant 
OUI Interim-Remedial Action Report Page 14 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

house was no longer utilized as an office building and all Nobis site management operations 

were relocated to the office trailer. 

Upon mobilization to the site, a perimeter fence had been erected around portions of the site, 

but was not continuous. During a reconfiguration of the site in preparation for Town 

redevelopment of the area in October 2004, the fence was modified to completely enclose the 

Nobis work area. 

4.2 Area 1 Overburden Monitoring/Injection Well Installation (NTCRA ISCO 

Program)

Between May 2004 and October 2004, 23 overburden ISCO injection wells (P2-04-series) and 

12 injection monitoring wells (IM-04-series) were installed in Area 1 (as part of Phase II) (Figure 

5). The ISCO injection wells were installed to allow for the injection of oxidants to the 

contaminated subsurface materials. The ISCO monitoring wells were installed to monitor the 

progression of the injection. During the drilling of the borings, the geology was logged and soil 

samples were screened for VOCs and sent for on-site and off-site VOC, metals, and organic 

carbon analyses. 

Each of the wells (with the exception of IM-04-08A, IM-04-08B, IM-04-09, IM-04-10, and IM-04-

11) was constructed of two-inch stainless-steel woven screen (10-slot) and solid riser sections. 

The exceptions were constructed of one-inch stainless-steel screen and riser sections. All wells 

were completed with concreted-in flush-mount H-20 load-rated road boxes. The tops of each of 

the wells were completed with threaded fittings to allow the installation of an additional riser to 

connect injection equipment. 

Table 3 summarizes the installation details for all Phase II ISCO injection and monitoring wells 

installed by Nobis as part of the NTCRA or RA. 

Once the wells were installed and developed, groundwater samples were collected from each of 

the wells to document the baseline overburden groundwater contaminant distribution. 

Additional baseline rounds of groundwater sampling were completed as prefixes to additional 

ISCO injections that were completed later in the Phase II ISCO program, and are described 

subsequently. 

The installation of the Phase II injection and monitoring wells, the soil boring geological logging, 

injection/monitoring well development, and baseline sample collection and results discussion 

were reported in March 2005 (Nobis, 2005a). 

4.3 Area 1 Bedrock Borehole Installation

In order to allow additional testing of the bedrock aquifer located beneath Area 1, a series of 15 

bedrock boreholes (BM-04-series and RB-04-series boreholes) were drilled in 2004 to depths as 

great as 300 feet below grade (Figure 5). The open boreholes were cased using 6-inch carbonsteel casing, and were sealed into competent bedrock using cement/bentonite grout. Each of 

the boreholes were completed with concreted-in flush-mount H-20 load-rated road boxes. The 

casings of three of the boreholes (BM-04-31, BM-04-35, and BM-04-36) were fitted with weldedon threaded collars to allow the connection of above-ground risers. These risers were 

constructed with a receiving-end of a pitless adapter welded-on for the purpose of hanging 

extraction pumps and allowing temporary aboveground piping to be utilized during pumping 

tests and dewatering activities. 
OUI Interim-Remedial Action Report Page 15 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

Table 3 summarizes the installation details for all Phase III bedrock boreholes installed by Nobis 

as part of the NTCRA or RA. 

The tests performed on the bedrock aquifer included a suite of down-hole geophysical tests, 

collection of rock samples for volatile organic compound (VOC) analysis, and the collection of 

packered-interval groundwater samples for VOC and inorganic analyses. 

Detailed descriptions of these installations and test results is included in the Conservative 

Tracer Test Design (Nobis, 2004b) and the 2005 Conceptual Model Update (Nobis, 2005a). 

4.4 Hydraulic Control Pumping Test and Conservative Tracer Test

The purpose of the Hydraulic Control Pumping Test was to determine if hydraulic control of 

groundwater inflows into the NTCRA Area 1 excavation could be maintained by sustained 

pumping of bedrock groundwater from a series of four bedrock boreholes located along bedding 

plane fracture strike and down bedding plane fracture dip of the contaminant source area 

coupled with pumping of the existing overburden groundwater extraction system. The pumping 

test was initiated in September 2004 and continued into October 2004 with the initiation of the 

CTT. Two additional extraction wells (EW-04-06 and EW-04-07) were installed in the shallow 

bedrock to assist in dewatering the overburden aquifer to a level acceptable for the CTT. Table 

3 summarizes the extraction well installation details. 

The CTT was performed in October 2004. The test was conducted to demonstrate the 

interconnectivity of the source area and the shallow weathered bedrock as well as provide data 

on dilution effects of injected fluids. The CTT was augmented with a modified PTT as well, 

where a suite of alcohols with differing partitioning coefficients were injected. The modified PTT 

was intended to provide data on the presence/absence of DNAPL as well as provide data on the 

efficacy of implementing a full-scale PTT in the more-competent bedrock. 

Approximately 760,000 gallons of groundwater was extracted from the NTCRA Area 1 

excavation and treated through the on-site temporary groundwater treatment plant during the 

pumping test and CTT/PTT. During the CTT/PTT, approximately 3,500 gallons of tracer 

solution was injected into the NTCRA Area 1 excavation followed by a 10,000-gallon water flood 

to assist in CTT solution migration into the bedrock. 

Detailed information regarding the performance of these tests is included in the 2005 

Conceptual Model Update (Nobis, 2005a). 

4.5 Area I Phase II ISCO Pilot Study

In November 2004, an appropriate oxidant was selected through bench- and field-scale pilot 

testing that demonstrated the feasibility and effectiveness of ISCO using ICP. These studies 

demonstrated that activated persulfate could persist in the subsurface long enough to allow 

sufficient oxidant distribution and would be effective in the destruction of the COCs. Based on 

the results of the ISCO pilot study, the use of activated persulfate for full-scale ISCO application 

was recommended. 
OUI Interim-Remedial Action Report Page 16 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

Specific elements of the ISCO Pilot Test are described subsequently: 

• Approximately 5,600 gallons of activated sodium persulfate/chelant solution and 

approximately 11,000 gallons of a modified Fenton’s Reagent/sulfuric acid were 

injected into separate portions of Area 1 using two injection wells each (four wells 

utilized in total). The injection itself was completed between November 10 and 

November 13, 2004. 

• Monitoring of the injection was performed in each test area using the previouslyinstalled ISCO monitoring wells. Monitoring consisted of geochemical 

parameters, oxidant concentrations, and total/ferrous iron concentrations in 

groundwater, and oxidant injection rates and pressures. 

• Subsequent confirmation soil and groundwater sample collection and analyses 

were completed in January 2005. 

The results of the Pilot Study were reported in March 2005 (XDD, 2005). 

4.6 Institutional Control Zone Establishment and Water Line Connections

A key component of the RA was the connection of residences to an existing public water supply 

(the Corinna Water District). The supply had been installed previously by others, and many of 

the residences and businesses in the area were already connected to it. Connection of 

residences to the water line was initiated in September 2005. 

The development of the ICZ included numerical modeling of bedrock groundwater flow and 

contaminant transport to evaluate the potential long-term migration of the bedrock plume under 

both pumping and non-pumping scenarios. 

Based on the results of ongoing bedrock groundwater monitoring and numerical groundwater 

modeling, it was determined that certain residences proximal to the Site, including Map 18 Lots 

39, 43, and 52, were currently impacted by Site contaminants or had the potential to be 

impacted in the future. These residences were connected to the existing public water supply 

between September and December 2005. 

Additionally, based upon the hydrogeologic investigations and groundwater modeling, a series 

of ICZs were delineated. Descriptions of these ICZs are included in a subsequent section of 

this report. Work is currently progressing towards full implementation of the ICZs. Details 

regarding the delineation of the ICZs is included in the July 2005 ICZ Task Plan (Nobis, 2005c). 

4.7 Area-Wide Groundwater Sample Collection

Between 2004 and 2007, annual groundwater monitoring events were conducted that included 

sample collection from on- and off-site overburden and bedrock monitoring wells as well as 

active and inactive drinking water supply wells. The objective of this monitoring was to assess 

groundwater quality in the overburden and bedrock aquifers in the vicinity of the source area, 

and provide a temporal evaluation of the overburden and bedrock groundwater contamination 

plumes. Prior to sample collection, groundwater level measurements were collected from select 

wells and used to develop potentiometric surface contours to assess overburden and bedrock 

groundwater flow. 
OUI Interim-Remedial Action Report Page 17 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

Table 4 summarizes each of the sampling events completed since 2004. 

Annual assessment reports include details regarding the sample locations, the samples 

collected, the analyses performed, and the results and data interpretation were submitted for 

each of these four rounds of monitoring (Nobis, 2005b; Nobis, 2006a; Nobis, 2007a; Nobis, 

2008b). 

4.8 Area 4 Overburden Monitoring/Injection Well Installation

4.8.1 Area 4 Phase I Mobilization and Site Preparation (NTCRA ISCO)

The Phase I ISCO work area included an earthen parking lot (formerly occupied by Building 14) 

that was utilized by the adjacent church and nearby businesses, flat grassy lawn/public open 

areas, and a sidewalk adjacent to Route 7 (Route 7 was realigned after Phase I activities were 

completed, such that the UST Area is now located at the approximate centerline of Route 7). 

Prior to installing the ISCO injection and monitoring wells in the Phase I ISCO work area, a 

gravelly sand layer was placed, graded, and compacted to provide a stable and well-drained 

working surface for equipment and personnel. Additionally, a temporary perimeter fence was 

erected around the work area to prevent access to the injection materials and equipment. At 

the conclusion of the Phase I injection activities the fencing was removed and fencepost holes 

were filled. 

4.8.2 Area 4 Phase I Installations (NTCRA ISCO)

Twenty ISCO injection wells (P1-05-series) were installed Area 4 (Phase I area); ten in the UST 

Area and ten in the Building 14 Area (Figure 6). The ISCO injection wells were installed to 

perform injections of activated sodium persulfate into the shallow and deep overburden to treat 

soil and groundwater contamination in these areas. Additionally, seven ISCO monitoring wells 

(IM-05-series) and four overburden monitoring wells (OM-05-series) were installed in this area 

to provide injection progression monitoring locations. 

All wells installed were constructed of two-inch polyvinyl chloride screen (10-slot) and riser 

piping. All wells were completed with concreted-in flush-mount H-20 load-rated road boxes. 

The tops of each of the wells were completed with threaded fittings to allow the installation of an 

additional riser to connect injection equipment (Nobis, 2005d). Table 3 summarizes the 

extraction well installation details. 

During the installations, soil samples were collected for VOC, metals, and organic carbon 

analyses to assist in defining the baseline contaminant distribution in subsurface soil. After the 

installed injection and monitoring wells were developed, baseline groundwater samples were 

collected for VOC metals, and several geochemical parameter analyses to determine the preinjection dissolved-phase contaminant distribution and geochemical makeup in overburden 

groundwater. 

Detailed information regarding the installations, sample collection methods, and the results of 

analyses performed were reported in May 2006 (Nobis, 2006b). 

4.9 Area 4 Phase I ISCO Injections (NTCRA ISCO)

The Phase I ISCO injection was completed in two separate events; one in July/August, 2005 

and the second in October/November, 2005. Each of the injections utilized an activated sodium 
OUI Interim-Remedial Action Report Page 18 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

persulfate solution as the oxidant. The solution was pumped to targeted injection wells in both 

the Building 14 and UST Areas. The progress and propagation of each of the injections was 

monitored using: water level data; groundwater geochemical parameters (pH, temperature, 

oxidation/reduction potential, specific conductivity, and dissolved oxygen); total and dissolved 

iron in groundwater; chloride in groundwater, oxidant concentrations in groundwater; oxidant 

concentrations in stormwater outfalls to the EBSR (to ensure oxidant was not impacting the 

drainage system); injection well back-pressure; injection pump back-pressure. Minor 

adjustments to the injection were made on an as-needed basis depending upon the results of 

the injection monitoring. Table 5 and Figure 6 summarize the total treatment fluid volume and 

oxidant mass injected during the two Phase I ISCO injections. 

The following summarizes the details of each injection. 

Phase I Injection 1

• Injection utilized 21 injection wells between the Building 14 and UST Areas. All 20 

injection wells plus one monitoring well (IM-05-13) that was converted to an injection 

well) 

• Approximately 13,400 gallons of activated sodium persulfate solution injected 

• The average injection rate during this injection was two gallons per minute 

Phase I Injection 2

• Injection utilized 17 injection wells between the Building 14 and UST Areas. Thirteen 

injection wells and four monitoring wells were utilized for injection. 

• Approximately 13,600 gallons of activated sodium persulfate solution injected 

• The average injection rate during this injection was two gallons per minute 

Injection performance assessments were performed after each of the two events. Each 

assessment consisted of a complete round of groundwater sample collection for VOC and 

chloride analyses followed by a soil boring program with soil samples collected and analyzed for 

VOCs. 

The Phase I Injection 1 performance assessment was performed in September 2005. The 

result of the assessment indicated that although contaminant mass was reduced, a second 

injection would be required to address remaining dissolved groundwater contamination in the 

Building 14 and UST Areas as well as a small amount of soil contamination detected in the UST 

Area. 

The Phase I Injection 2 performance assessment was performed in December 2005. The result 

of the assessment indicated that two small areas of soil contamination above cleanup goals 

remain in the UST area; however, additional applications of oxidant was not recommended as it 

was not believed that additional reduction in the small remaining contaminant mass could be 

efficiently achieved. 

Detailed information regarding the ISCO injection, monitoring, and performance assessment 

were reported in May 2006 (Nobis, 2006b).

4.10 Area 4 Phase I Monitoring/Injection Well Abandonment

Two separate well abandonment efforts were completed in 2006, the first of which was in May 

of 2006, the second in September 2006. Table 6 provides a summary of the well abandonment 

activities completed in 2006. 

4.10.1 Area 4 UST Area Well Abandonment (RA)

Due to a 2006 realignment of Route 7 by the Maine Department of Transportation (MEDOT), 

monitoring and injection wells installed in the UST Area were abandoned in May 2006 using a 

cement/bentonite grout. The associated roadbox and concrete apron were excavated, and the 

excavations were backfilled, graded as-needed, and compacted using a plate compactor. The 

abandonment of the wells located within the proposed right-of-way was coordinated with the 

MEDOT. 

4.10.2 Area 4 Building 14 Area and Map 18 Lot 88 Well Abandonment (RA)

In September 2006, the ISCO injection and ISCO monitoring wells located in the Building 14 

Area were abandoned utilizing the same abandonment techniques as the UST Area wells. All 

overburden monitoring wells were not abandoned and several incorporated into the long-term 

monitoring scheme. 

Three monitoring wells (2 overburden wells and one bedrock well) located on the Map 18 Lot 88 

parcel were utilized during the RI/FS phase of the project to assist in delineation of 

contamination detected on that parcel. After Weston completed a limited excavation on that 

parcel as part of the NTCRA, and subsequent groundwater samples indicated that groundwater 

cleanup goals had been met in the area, the three wells were abandoned in September 2006 

utilizing the same well abandonment technique as described above. 

4.11 Area 1 Phase II ISCO Injections

Between 2005 and 2007, three separate full-scale ISCO injections were performed in the Area 1 

Phase II portion of the site. These injections were designed to treat residual contaminant mass 

contained in the overburden directly overlying weathered bedrock and the dissolved-phase 

groundwater contamination in this area. 

Preceding each of these ISCO injections, groundwater samples were collected to estimate 

contaminant rebound from previous injections, as well as to establish a baseline contaminant 

distribution. 

Each of the injections utilized activated sodium persulfate as the oxidant which was pumped into 

injection wells. The progress and propagation of each of the injections was monitored using: 

water level data; groundwater geochemical parameters (pH, temperature, oxidation/reduction 

potential, specific conductivity, and dissolved oxygen); total and dissolved iron in groundwater; 

chloride in groundwater, oxidant concentrations in groundwater; injection well back-pressure; 

injection pump back-pressure. Minor adjustments to the injection were made on an as-needed 

basis depending upon the results of the injection monitoring. 

Table 7 and Figure 7 summarize the total treatment fluid and oxidant mass injected in to each 

well within the Phase II area.

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

The following summarizes the details of each injection. 

Phase II Injection 1 (NTCRA ISCO)

• Injection was completed in mid-September 2005 using 11 injection wells broken into two 

injection groups 

• Approximately 38,679 gallons of activated sodium persulfate solution injected 

• The cumulative injection rate during this injection ranged between 12 to 15 gallons per 

minute 

A round of ISCO performance assessment groundwater sample collection was completed in 

November 2005 in an effort to determine the post-injection contaminant distribution. The 

groundwater samples were collected for VOC and chloride analyses. No soil sampling was 

completed as part of the injection 1 performance assessment. 

The analytical results of the performance assessment groundwater samples indicated that 

dissolved contaminant mass had been reduced by approximately 63% when compared to 2004 

baseline groundwater contaminant mass. Therefore, additional Phase II injections were 

recommended. 

Detailed information regarding the ISCO injection, monitoring, and performance assessment 

were reported in May 2006 (Nobis, 2006b). 

Phase II Injection 2 (RA)

• Injection was completed in late-October into early November 2006 using 22 injection 

wells broken into three injection groups 

• Approximately 34,717 gallons of activated sodium persulfate solution injected 

• The cumulative injection rate during this injection ranged between 10 to 18 gallons per 

minute 

The Phase II Injection II ISCO performance assessment soil and groundwater sample collection 

was completed in January and February 2007. The assessment was completed to determine 

the post-ISCO injection soil and groundwater contaminant distribution and estimate contaminant 

mass. 

The soil samples were collected for VOC analyses while the groundwater samples were 

collected for VOC and total/dissolved iron analyses. 

The findings of the performance assessment indicated that residual soil contaminant mass had 

been reduced by approximately 75% while the groundwater sample analytical results yielded an 

increase in dissolved contaminant mass. It was theorized that desorption of residual DNAPL in 

the deep overburden and weathered bedrock may have contributed to the increased dissolved 

contaminant mass estimate. 

Detailed information regarding the ISCO injection, monitoring, and performance assessment 

were reported in May 2007 (Nobis, 2007b).

Phase II Injection 3 (RA)

• Injection was completed in mid-September 2007 using nine injection wells broken into 

two injection groups. This Phase II injection was completed simultaneously with a 

shallow bedrock ISCO injection completed as part of Phase III (described in a 

subsequent section). 

• Approximately 29,143 gallons of activated sodium persulfate solution injected 

• The cumulative injection rate during this injection ranged between 10 to 18 gallons per 

minute 

In November 2007, ISCO performance assessment groundwater samples were collected to 

assist in the determination of the post-injection groundwater contaminant distribution, and 

dissolved contaminant mass. The groundwater samples were collected for VOC and chloride 

analyses. No soil sampling was completed as part of this performance assessment. 

The analytical results of the performance assessment groundwater samples indicated that 

dissolved contaminant mass had been reduced by approximately 70% when compared to 2004 

baseline groundwater contaminant mass. 

The performance assessment report provided recommendations that included the completion of 

a comprehensive soil and groundwater contaminant assessment. The assessment could be 

utilized in determining the distribution of contaminants as well as highlight areas requiring 

supplemental injections. 

Detailed information regarding the ISCO injection, monitoring, and performance assessment 

were reported in April 2008 (Nobis, 2008a). 

Details pertaining to the ISCO injection, monitoring, and performance assessment is provided in 

the 2007 Phase II and Phase III ISCO Remedial Performance Assessment, dated April 28, 

2008. 

4.12 Area 1 Phase III Injection, Monitoring, and Extraction Well Installations (RA)

Between June and July 2006, four injector wells were installed in soil borings advanced 

proximal to RB-04-05 in an effort to access more of the most-highly contaminated shallow 

weathered bedrock and basal till, as defined during previous investigations (Figure 8). These 

wells were constructed of two-inch PVC screen (10-slot) and riser sections. Each of the four 

wells were completed with concreted-in flush-mount H-20 load-rated road boxes. The tops of 

each of the wells were completed with threaded fittings to allow the installation of an additional 

riser to connect injection equipment. 

In August 2006, four removable Waterloo® multilevel sampling systems were installed in 

existing rotosonic bedrock boreholes (RB-04-02, RB-04-03, RB-04-05, and RB-04-07). These 

systems provide a borehole seal at consistent depths using low-pressure borehole packers 

(manufactured of Viton ®), and contain stainless-steel double valve pumps set at the proper 

depths (Table 3 provides an installation summary). These pumps are connected to Teflon®-

lined tubing, which allow samples to be drawn from the sealed intervals. Additionally, the casing 

of the system is constructed of inter-locking schedule-80 PVC riser sections. These sampling

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

systems were installed to allow groundwater sample collection from multiple depth intervals 

within bedrock boreholes, which would allow for near-simultaneous monitoring of both Phase III 

and Phase IV ISCO applications. 

In June 2006, two four-inch extraction wells (EW-06-08 and EW-06-09) were installed within the 

footprint of the Area 1 excavation (Table 3 provides an installation summary). These wells were 

installed to support the dewatering effort by intersecting shallow bedrock/deep overburden 

groundwater entering the former excavation area from higher elevations to the west. The wells 

were constructed of four-inch PVC screen (10-slot) and riser sections, and were completed with 

concreted-in flush-mount H-20 load-rated road boxes. The tops of each of the wells were 

completed with threaded fittings to allow the installation of an additional riser similar for the 

purpose of suspending an extraction pump in a fashion similar to what was described in an 

earlier section of this report. 

Detailed information regarding the Phase III installations, sample collection, and analytical 

results were reported in April 2008 (Nobis, 2008a). 

4.13 Area 1 Phase III ISCO Injections (RA)

Between 2006 and 2007, two separate full-scale activated persulfate ISCO injections were 

performed in the overburden till and shallow weathered bedrock directly beneath the Phase II 

area. Table 8 and Figure 9 summarize the total treatment fluid volume and oxidant mass 

injected into each well. 

The following summarizes the details of each injection. 

Phase III Injection 1

• Injection was performed as a two-stage activated sodium persulfate flood of a dewatered 

NTCRA excavation bottom. 

• The floods were completed in mid-October 2006 (immediately preceding the Phase II 

injection 2) using the four Phase III ISCO injection wells, the two newly-installed Phase 

III extraction wells, and a pre-existing extraction well. 

• Approximately 35,054 gallons of activated sodium persulfate solution injected 

• The cumulative injection rate during this injection ranged between 10 to 18 gallons per 

minute 

In January 2007, ISCO performance assessment groundwater samples were collected to assist 

in the determination of the post-injection groundwater contaminant distribution, and dissolved 

contaminant mass. The groundwater samples were collected for VOC analysis. 

Detailed information regarding the ISCO injection, monitoring, and performance assessment 

were reported in May 2007 (Nobis, 2007b). 

Phase III Injection 2

• Injection was performed as an activated sodium persulfate flood of a saturated NTCRA 

excavation bottom.

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

• The floods were completed in mid-September 2007 using the four Phase III ISCO 

injection wells. 

• Approximately 14,566 gallons of activated sodium persulfate solution injected 

• The cumulative injection rate during this injection ranged between 7 to 8 gallons per 

minute 

In November 2007, ISCO performance assessment groundwater samples were collected to 

assist in the determination of the post-injection groundwater contaminant distribution, and 

dissolved contaminant mass. The groundwater samples were collected for VOC and dissolved 

iron analysis. 

Detailed information regarding the ISCO injection, monitoring, and performance assessment 

were reported in April 2008 (Nobis, 2008a). 

4.14 Long-Term Monitoring Well Installation (RA)

 

Between June and September 2006, a series of overburden and bedrock monitoring wells were 

installed. These wells were installed as part of the long-term response actions (LTRA) to assist 

in the monitoring of the dissolved groundwater contamination plume at the site. A total of 11 

overburden monitoring wells and four bedrock monitoring wells were installed in areas 

throughout the center of Corinna (Figure 10). All wells were constructed of two-inch threaded 

PVC screen (10-slot) and riser sections (Nobis, 2006a). Details pertaining to the installation of 

these LTRA monitoring wells can be found on Table 3. 

All wells were developed and subsequently groundwater samples were collected. The 

groundwater sample collected from bedrock monitoring well BM-06-44 exhibited concentrations 

of site contaminants that were consistent with groundwater samples collected from bedrock 

wells installed in the source area, which was not anticipated. 

The detection of these contaminants in BM-06-44 prompted additional bedrock groundwater 

investigation in the area of BM-06-44. This investigation was termed the East Side 

Characterization. Details pertaining to this investigation are described subsequently. 

4.15 Area 1 Phase IV ISCO Injection Well Installation (RA)

In June 2007, nested deep bedrock ISCO injection wells were installed in pre-existing bedrock 

boreholes BM-04-34, BM-04-35, and BM-04-37. However, due to a problem encountered 

during installation, the placement of nested wells in BM-04-35 was not completed and the 

targeted depth of installation in BM-04-37 was modified. The installation of nested wells in BM04-34 was completed as specified (Nobis, 2007c). 

Two additional bedrock boreholes BM-07-51 and BM-07-52 were installed in July and August 

2007 to supplement BM-04-34 and BM-04-37 (Figure 11). Down-hole borehole geophysical 

testing was completed in these two new boreholes to determine if appropriate fractures were 

intersected by the boreholes. After assessment of the geophysical data was completed, a 

revised approach to the Phase IV Pilot Test was developed, and a series of nested wells were 

installed in BM-07-51. 
OUI Interim-Remedial Action Report Page 24 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

These installed bedrock boreholes were cased into bedrock using 6-inch carbon steel casing. 

Additionally, the nested well components were schedule-80 PVC and were either 1-inch ID or 2-

inch ID (Nobis, 2007c). Table 3 summarizes the installation details for the nested Phase IV 

ISCO injection wells. 

4.16 Area 1 Phase IV ISCO Pilot Test (RA)

A field-scale pilot test of the deep bedrock ISCO injection (i.e., Phase IV) was initiated in August 

2007 and completed in September 2007. The test utilized three of the four nested wells 

installed previously (Figure 12) (Nobis 2007c). The test was designed as a “push-pull” test, 

whereby the activated sodium persulfate solution was mixed with a conservative tracer prior to 

injection. The oxidant was allowed a sufficient reaction time in-ground prior to the pull or 

extraction phase of the test. During the extraction phase, samples of the extracted fluid are 

analyzed for oxidant concentration, tracer concentration, and VOC concentration. These data, 

when considered collectively assist in evaluating the degree of oxidant decomposition, dilution, 

and yield an overall evaluation of ISCO efficiency in the bedrock aquifer. The major elements of 

the pilot test are described subsequently. 

Table 8 provides a summary of the Phase IV Pilot Test treatment volume and mass injected into 

each injection well. 

• Injected approximately a total 300 gallons of an activated sodium persulfate and sodium 

bromide tracer solution into the three Phase IV ISCO injection wells (54 gallons into BM04-34, 120 gallons into BM-04-51, and 120 gallons of solution into BM-04-37). 

• Extracted a total of 708 gallons of fluid from the three wells (27 gallons from BM-04-34, 

396 gallons from BM-07-51, and 285 gallons from BM-04-37). 

• Injection and extraction monitoring for geochemical parameters, total and dissolved iron, 

VOCs, and sodium. 

The evaluation of the results of this test is on-going. 

4.17 East Side Characterization (RA)

The objective of this investigation was to determine if the contamination detected in 2006 in 

long-term monitoring well BM-06-44 represented a new source that was not associated with the 

Area 1 source, or if the contamination was contiguous with the Area 1 source area. This 

investigation, termed the East Side Characterization, included the installation of five bedrock 

boreholes (BM-07-series), down-hole geophysical testing of the boreholes, and packer-interval 

groundwater sample collection and analysis (Figure 12). The installation details for these 

bedrock boreholes are included in Table 3. 

The investigation concluded that the contamination detected in bedrock groundwater in the area 

proximal to BM-06-44 is associated with the Area 1 source area contamination, and that a 

separate source of groundwater contamination is not suspected. Additional details pertaining to 

this investigation were reported in 2008 (Nobis, 2008c).

4.18 Investigation Derived Waste Treatment/Transport/Disposal

Drill cuttings generated during the installation of the various overburden and bedrock 

injection/monitoring/extraction wells were either containerized for proper transport and disposal 

or in the case of uncontaminated drill cuttings, reused at the site. Additionally, spent GAC and 

field-laboratory liquid wastes were also generated during completion of site activities and on-site 

sample analyses. 

Table 9 summarizes the manifested materials shipped off-site for disposal, and Appendix B 

includes the manifests and profiles for the shipments made. 

In addition to manifested wastes, over 1.5 million gallons of liquid wastes including groundwater 

sample purge water, groundwater extracted during pumping tests, and groundwater extracted 

during excavation dewatering were all treated through the use of the temporary groundwater 

treatment system. Collection pre-, mid-, and post-treatment samples were collected. All 

reported results were within discharge limits as prescribed by Weston’s operations and 

maintenance manual. 

During the 2006 aquifer dewatering effort, post-treatment samples were collected and analyzed 

and indicated that discharge criteria for manganese and chloromethane had been exceeded. 

As a result of these exceedances, the treatment system was reconfigured to maximize carbon 

contact time. No additional exceedences of discharge limits were noted in follow-up post 

treatment samples.

6.0 PERFORMANCE STANDARDS AND CONSTRUCTION QUALITY CONTROL

This section provides an analysis of the performance standards and quality control associated 

with the remedial action performed at the EWM site. All work performed at the Site was 

consistent with the Action Memorandum, OUI ROD, and the final design for the NTCRA and 

OUI. EPA, on its own, and through the USACE performed oversight of the NTCRA and OUI 

construction activities in addition to the quality control and quality assurance activities performed 

by the contractor. 

All sampling was implemented using EPA, American Society for the Testing of Materials 

(ASTM), or other standard practices. All construction quality and performance data was 

reviewed by EPA as part of the oversight of the construction activities. The data pertaining to 

the limits of excavation and the treatment of soil along with the performance data from the insitu oxidation program was used to document the achievement of the design requirements for 

these components of the work. Ambient air sampling was performed to confirm compliance with 

the Maine Ambient Air Guidelines and EPA risk based standards during the excavation and exsitu treatment activities. 

All construction quality control and quality assurance information is available at the EPA Region 

I Records Center in Boston, MA. The Quality Assurance/Quality Control (QA/QC) program 

utilized throughout the construction program was sufficiently rigorous and was adequately 

complied with to enable EPA and the State to determine that the results reported are accurate 

to the degree needed to assure satisfactory execution of the NTCRA consistent with the Action 

Memorandum and the OUI ROD and the accepted design for OUI. 

6.1 Construction Quality Control

 

In addition to the oversight provided by EPA and Maine DEP, the Army Corps of Engineers 

regulation ER-1180-1-6 (i.e., construction quality management) procedures were applied to the 

work at the Site. USACE required that the Three-Phase System for Contractor Quality Control 

was utilized. The system is summarized below (and is described in more detail in the USACE 

Guide to Effective Contractor Quality Control (CQC); EP-715-1-2: 

• The work assignment is to be parsed into definable features of work (DFOW) 
OUI Interim-Remedial Action Report Page 29 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

• For each DFOW, a series of three inspections are to be completed. Each inspection is 

designed to minimize to the extent possible errors or clarifications prior to, or as early in 

the construction phase as possible to minimize rework 

• The first inspection is the Preparatory Inspection; key information pertaining to the 

inspection is summarized below: 

o Attended by pertinent contractor personnel as well as the Contracting Officer’s 

Representative (COR) and/or the government resident engineer 

o Completed prior to the work on the DFOW is initiated; similar to a preconstruction meeting 

o Inspections of construction materials is to be completed 

o The results of any required materials testing is to be reviewed and approved 

o Health and safety issues are discussed 

• The second inspection is the Initial Phase Inspection; key information pertaining to the 

inspection is summarized below: 

o Attended by pertinent contractor personnel as well as the COR and/or the 

government resident engineer 

o Completed after the initial work on the DFOW is completed to ensure that 

contractor understanding of the DFOW is adequate and the workmanship is 

sufficient 

o Ensure any action items identified in the Preparatory Phase Inspection are 

examined 

o Identify and correct any deficiencies noted 

• The third inspection is the Follow-Up Phase Inspection; key information pertaining to the 

inspection is summarized below: 

o This is generally a daily construction inspection to document site activities, any 

materials or workmanship testing completed, the results of these tests, 

documentation of craft labor and equipment on-site, and any corrective actions 

given or received 

Each of these inspections was completed for the DFOWs identified during work completion at 

the EWM site. Numerous DFOWs were identified throughout the course of the site operations. 

During the completion of site work, deviations to approved plans were required, and a summary 

of the most-significant deviations is presented below: 

• 2004 - Inability to install bedrock borehole BM-04-33 

This was due to unfavorable geologic conditions for the use of air-hammer 

drilling; essentially the air pressure that was meant to return drill cuttings to the 

surface was short-circuiting into adjacent overburden ISCO injection and 

monitoring wells, which could have potentially damaged the injection wells. It 

was determined that the borehole should not be completed to the design depth to 

prevent damage to in-place wells. The partially-installed borehole was 

completed at the surface in a similar fashion to the remaining boreholes (i.e., H20 load rated roadbox and concrete apron). 

• 2004 – Insufficient bentonite seal added to completely seal overburden injection well P2-

04-12. A second well was installed adjacent to P2-04-12, and was named P2-

04-12R. The initial P2-04-12 was utilized as a monitoring well.

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

• 2007 – Incorrect installation of nested bedrock ISCO injection wells 

This was due to a subcontractor miscalculation of the volume of 

cement/bentonite grout required for installation thereby sealing the targeted 

bedrock fractures with grout. Additional bedrock injection well locations were 

installed to correct the error. 

All inspection records completed for this project were submitted to the USACE Resident 

Engineer. EPA and the Maine DEP were involved in the inspections and site meetings. EPA 

and Maine DEP performed periodic inspections and reviewed the progress reports and data 

generated during the implementation of the NTCRA and RA. 

6.2 Analytical Data Quality Control

Prior to initiating field activities, a Quality Assurance Project Plan (QAPP) was completed. The 

QAPP set-forth the data-quality objectives (DQOs), the quality assurance acceptance criteria, 

the analytical methods required, the field data collection methods, the sample collection 

methods, laboratory quality control requirements, data validation requirements, auditing 

requirements, etc. 

Throughout the course of site activities, approximately 2,500 environmental samples were 

collected for a variety of analyses. In accordance with planning documents and the QAPP, data 

validation was to be completed for baseline soil and groundwater data, performance 

assessment soil and groundwater data, and area-wide monitoring groundwater data. Data 

validation was completed in accordance with the QAPP and the EPA New England Functional 

Guidelines for Evaluating Environmental Analyses. Data validations of these data were at a rate 

of 90% Tier-II and 10% Tier-III (Nobis, 2004a). 

After each validation was completed, an overall data quality assessment was completed. This 

assessment involved a comparison to the data to their respective DQOs. Almost all data 

collected and validated was found to be acceptable for project use. Only a minimal amount of 

data was found to be inadequate, and of these data only a small portion involved site 

contaminants of concern. 

6.3 Remedy Performance

The OUI ROD-mandated cleanup goals for the EWM Site are summarized on Table 2. 

During the course of the project, a retraction of the overburden and bedrock groundwater 

contaminant was noted. 

The general objective of the GW-4a in-situ treatment program was to maximize reduction of 

residual sources of contaminant mass as a strategy to achieve aquifer restoration in a 

reasonable time frame. The Site FS presented a general contaminant mass reduction estimate 

of 85% as a precussor to achieve aquifer cleanup goals in less than 100 years. It was not 

anticipated that groundwater cleanup and complete aquifer restoration would be achieved at the 

completion if the ISCO program. Rather, continued reduction of dissolved contaminants would 

be achieved through biostimulation and natural attenuation. Therefore, the achievement of 

ROD cleanup goals is not necessarily a metric used to measure the success of the in-situ RA.

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

Based upon contaminant mass estimates completed throughout the course of the project, an 

approximate 75% to 85% contaminant mass reduction has been achieved to date. Future 

monitoring will include additional soil and groundwater sampling. These data will be used to 

refine the remaining contamination, evaluate the overall in-situ remedial performance, and 

provide qualitative estimates of overall time required for restoration. 

1,350 kilograms of Phase II sorbed/residual soil contaminant mass (representing approximately 

73%, when compared to soil data collected in 2004) was destroyed. Approximately 83% of the 

2004 dissolved overburden groundwater contaminant mass was destroyed by 2007. The 

overall success of the RA is also exhibited by the downward-trending average contaminant of 

concern concentration in the overburden groundwater. The average overburden groundwater 

contaminant of concern concentration has been reduced 78%, when compared to the average 

concentration in 2004. Bedrock groundwater samples collected in association with Phase III 

ISCO activities also indicate an overall decline (49% of total COCs, when compared to baseline 

2006 concentrations) in groundwater contaminant concentrations. 

Soil contaminant mass that existed in the Phase I area has been all but eliminated (two areas of 

soil contamination remain in the UST Area beneath the realigned Route 7. Additionally, 

overburden groundwater contamination in this area has also declined since the performance of 

the ISCO injections. 

Additional ISCO injections will occur as part of LTRA to further reduce the contaminant mass in 

the overburden and bedrock. 

7.0 FINAL INSPECTION AND CERTIFICATIONS

This section provides a summary of the construction completeness and Final Inspections. 

7.1 Contract Inspections

During the completion of the RA activities at the EWM site, numerous construction inspections 

were performed. As stated previously, the USACE Three-Phase System of Construction Quality 

Control was implemented at the site. Through the use of these systematic inspections, the 

Construction-Completion inspection was held on September 19, 2006. The construction 

completion inspection attendees are listed below: 

• Ed Hathaway – U.S. Environmental Protection Agency 

• Rebecca Hewett – Maine Department of Environmental Protection 

• Fred Lavallee – Maine Department of Environmental Protection 

• Hank Andolsek – Maine Department of Environmental Protection 

• Scott Acone – U.S. Army Corps of Engineers 

• David O’Conner – U.S. Army Corps of Engineers 

• Andrew Boeckeler – Nobis Engineering, Inc. 

• Denis McGrath – Nobis Engineering, Inc. 

• Amy Adams – Nobis Engineering, Inc. 

As a result of these inspections, the remedy was deemed construction complete on September 

28, 2006 as documented in “ SUPERFUND SITE PRELIMINARY CLOSE OUT REPORT (NonTime Critical Removal Action and Final Site Action – OUI), Eastland Woolen Mill 

Superfund Site, Corinna, Maine, September 2006”.

7.2 Final Inspection

A Pre-Final Inspection was completed on August 4, 2008. The inspection attendees were as 

follows: 

• Ed Hathaway – U.S. Environmental Protection Agency 

• Rebecca Hewett – Maine Department of Environmental Protection 

• Jason Fopiano – Nobis Engineering, Inc. 

No site-construction related punch-list items were identified during the inspection. As no punchlisted items were noted, this inspection was also considered the Final Inspection. 

7.3 Adherence to Health and Safety Requirements

Comprehensive site-specific health and safety plans (HASP) were implemented during RA 

activities at the EWM site. The initial HASP was dated April 2004, and was utilized until it was 

updated on July 25, 2007. 

As required by the HASP and the USACE, Nobis provided a dedicated Site Safety and Health 

Officer (SSHO) to provide oversight of all health and safety-related actions. The SSHO 

completed daily safety briefings, conducted work zone air monitoring, and conducted daily site 

health and safety inspections. 

During the RA implementation, no lost-time incidents or Occupational Safety and Health 

Administration (OSHA)-recordable injuries or illnesses were had at the site. Injuries such as 

small cuts, abrasions, and bruises were dealt with using first-aid procedures. The SSHO daily 

inspections identified the occasional health and safety issue such as inappropriate or lack of 

appropriate personal protection equipment (PPE). In each circumstance, immediate corrective 

action to the issue was implemented. 

7.4 Institutional Controls

As part of the ROD selected remedy, several ICs were identified as necessary to eliminate the 

potential for consumption of contaminated groundwater, and minimize the possibility of 

enhanced contaminant transport due to bedrock groundwater pumping stresses. The following 

list summarizes the ICs at the EWM site: 

• ICZ-A properties will be permanently prohibited from residential, commercial, or 

industrial groundwater withdrawal. The ICZ-A properties include whole parcels that 

currently use public water or are eligible to have existing private water well supplies 

replaced by public water. These properties will be subject to restrictive covenants, 

prohibiting use of groundwater, over the entire property. Within the ICZ-A boundary, all 

existing bedrock and overburden water supply wells will be formally decommissioned, 

unless the wells are converted to monitoring wells for use in the LTRA. 

• ICZ-B properties will be prohibited by restrictive covenants from installing future 

groundwater wells in locations and/or depths that differ from existing water supply wells 

located on the property. Properties that currently use public water within this zone can 

remain on public water. Properties that currently use private water wells within this zone 

for domestic or other uses may continue use of those wells. Any new commercial or 

industrial use of existing water supplies within an ICZ-B should be subject to Town 

review and approval through the Planning Board or similar group. As of the writing of 
OUI Interim-Remedial Action Report Page 33 

 

USACE Contract No. DACW33-03-D-0005 Eastland Woolen Mill Superfund Site, 

Document Tracking No.: 74012.08-RACR.01 Corinna, Maine 

this report, there are no ICZ-B properties since all of the former ICZ-B properties have 

been connected to the waterline, moving them to the ICZ-A category. 

• ICZ-C properties are located within the ICZ-A boundary, which may continue to utilize 

the existing drinking water well, but new well locations and depths are prohibited. 

Figure 13 summarizes the ICZ delineation and provides a description of each of the ICZs. 

As stated previously, the implementation of the ICZs is currently on-going. 

8.0 OPERATION & MAINTENANCE ACTIVITIES

This section describes the elements required to operate and maintain the RA and activities 

required to achieve aquifer restoration. 

8.1 Long-Term Response Action Supplemental Injections

Periodic follow-up injections of oxidants and/or amendments to the overburden and/or bedrock 

aquifers will be required to treat contaminant rebound and/or residual contamination and to 

achieve aquifer restoration. Additional soil and groundwater monitoring will be required to 

monitor the progression of the injection and to provide data necessary to gauge the relative 

success of each injection. The anticipated sample analyses will include (at a minimum) VOCs 

and total and dissolved metals. Soil samples will be analyzed for VOCs at a minimum. Each of 

these supplemental injections will require separate mobilizations as it is anticipated that site 

infrastructure will be demobilized and/or decommissioned. 

The wells to be utilized for either ISCO injection amendments or associated monitoring are 

summarized on Figure 14. 

8.2 Long-Term Response Action Monitoring

As aquifer restoration has not been achieved, LTRA monitoring will be required to monitor the 

overburden and bedrock groundwater potentiometric surfaces, contaminant plume extents, 

monitor the surface water and sediment within the EBSR, and ensure that residents proximal to 

the EWM site that remain on private drinking water are not exposed to contaminated 

groundwater. 

As a precursor to the LTRA monitoring, several rounds of “Area-Wide Groundwater Monitoring” 

have been completed. Each of these monitoring events were designed to achieve the goals 

stated above, as well as assist in selection of proper monitoring locations and assist in 

determining new locations. As a result, eleven additional overburden monitoring wells and nine 

additional bedrock monitoring wells were installed. 

The LTRA monitoring will consists of annual overburden and bedrock groundwater elevation 

measurements, overburden and bedrock groundwater sample collection for VOC and metals 

analyses, EBSR surface water and sediment (every five years) sample collection for VOC and 

metals analyses, river bank inspections, ICZ monitoring/inspections, and initiation of the FiveYear Review process. 

Groundwater and surface water samples will be collected from the locations identified on Figure 

15. Additionally, out-of-use monitoring wells shall be abandoned in accordance with Maine

regulation. Figures 16 and 17 summarize the monitoring wells/bedrock boreholes that are to be 

abandoned within the OUI and OU2 areas at the end of the LTRA period, respectively. 

8.3 Five-Year Reviews

Since contamination remains in the groundwater above levels that would allow for unrestricted 

use of the Site, EPA will perform Five-Year Reviews for the Eastland Woolen Mill OUI Remedial 

Action. The Five-Year Review will be completed utilizing the most-recent version of the EPA 

Five-Year Review preparation guidance. The first Five-Year Review is scheduled for 2010. 

9.0 SUMMARY OF PROJECT COSTS

This section summarizes the RA costs incurred to date, and a comparison of the actual costs to 

the adjusted ROD estimates. Although the RA is a treatment remedy, it is an in-situ remedy and 

as such a true cost analysis on a per-unit-treated is not feasible. However, as the project has 

matured, the overall treatment efficiency has been estimated, and as of the 2006 ISCO 

program, the full-scale treatment efficiency noted in the Phase II area was approximately 22 

pounds of oxidant per pound of contaminant mass destroyed. 

9.1 Actual Project Cost Summary

Table 10 provides a summary of the costs associated with the implementation of the RA; 

NTCRA costs are not included in this summary. 

Appendix A provides a more-detailed cost summary and comparison to ROD-estimated costs. 

10.0 OBSERVATIONS AND LESSONS LEARNED

The following section describes some important observations and lessons learned pertaining to 

the NTCRA and OUI RA activities. 

10.1 Drilling Activities

The Roto-sonic drilling technique proved to be an invaluable tool for soil and shallow weathered 

bedrock sample collection. Due to the density of the till, conventional drilling methods involving 

a split spoon may not have been capable of providing adequate sample for geologic description 

and sampling. The Roto-sonic core was continuous and large-enough to obtain relatively 

undisturbed sample from the interior of the soil core. Additionally, it allowed for the inspection of 

the core for the presence of visible DNAPL. Of particular importance was the discovery of a 

layer of highly-weathered/pulverized rock at the till-bedrock interface. This layer was highlyconductive and may have provided a contaminant transport pathway for site contaminants. 

In addition to providing quality soil samples, the amount of time required to advance and recover 

drilling tools from the borehole was less than that of the more-conventional drilling methods, 

which reduced the overall time required per borehole. 

If overburden and bedrock characterization programs are to be completed at the same time in 

the same general location, and bedrock drilling is to use air-hammer techniques, then the 

bedrock drilling should be conducted first so as to prevent damage to the overburden locations.

10.2 ISCO Activities

Sodium persulfate ISCO reactions result in the generation of off-gas (composed primarily of 

CO2) leading to mounding conditions in the overburden and bedrock aquifers and in some 

instances small surface breakouts of groundwater and reagent solutions. The buildup of 

subsurface gasses can result in subsurface pressure gradients that cause expulsion of gasses 

and/or fluid from nearby monitoring wells. Care should be taken when collecting samples from 

wells in the area of the injection(s). In particular, nearby wells must not be capped to eliminate 

the potential for over-pressurization of the well headspace. Subsurface pressure must be 

monitored during active ISCO injections, as well as during post-injection sampling. 

10.3 Electronic Data Management

During the course of this project, the use of laboratory electronic data deliverables coupled with 

an electronic sample tracking system allowed data to be processed rapidly. With the quantity of 

data generated during this project, the use of an analytical results database was essentially 

required. Nobis developed a project-specific analytical database for the purpose of analyzing 

data rapidly and without error. This functionality proved to be a valuable tool in the data 

analysis stage of the project.
