## 1 1.0 INTRODUCTION

The Te tra Tech , Inc. (Tetra Tech) Superfund Technical Assessment and Response Team (START) was tasked by the U.S. Environmental Protection Agency (EPA) Region 7 Superfund Division to provide removal support at the Callahan Property site in Wildwood, Missouri

. T he Callahan Property site is a sub

- site of the Ellisville Superfund site. A removal action (RA) was conducted to address contaminated soil associated with buried drums previously removed from the site

. Illegal burial of the drums ( and possibly other wast e materials ) was identified in previous investigations as the likely source of soil contamination a t the Callahan Property site

. For the RA, START was requested to document removal activities, conduct real

- time air monitoring for volatile organic compound s (VOC) , conduct in

- situ x

- ray fluorescence (XRF) screening of soils for metals (lead in particular) regulated by the Resource Conservation and Recovery Act ( RCRA ) , and collect soil samples for laboratory analysis

. A nalytical results were compared to EPA Regional Screening Levels (RSL)

. The START project manager was Christina Engemann , and the EPA Region 7 Project Manager for the RA was Laura Price

.

2.0 SITE LOCATION AND ENVIRONMENTAL SETTING
The City of Ellisville is in the vicinity of the intersection of Missouri Highway (MO)

- 340 (also known as Clarkson Road) and MO

- 100 (also known as Manchester Road) (see Appendix A, Figure 1) . The Callahan Property site (C omprehensive Environmental Response, Compensation , and Liability Information System [C ERCLIS ] No. M OD980633010 [for the Ellisville site] ) encompasses approximately 8.3 acres of predominantly wooded land, with a barn adjacent to and east of the area that was excavated

. The Callahan Property site is in Section 31 of Township 45 North, Range 4 East. The surrounding land use is predominantly for residential housing. The geographic coordinates of the site are 38.596662 degrees north latitude and 90.605733 degrees west longitude.

2.1 SITE GEOLOGY, HYDROLOGY, AND HYDROGEOLOGY
The site is in an area of gently r olling terrain, at an elevation of approximately 680 feet above sea level. S oils are classified as Goss gravelly silt loam and the Urban land

- Harvester complex, and are underlain by Ordovician rocks (United States Department of Agriculture [USDA] 2013)

. The thick sequence of Ordovician strata mostly consist s of dolomite and limestone interbedded with minor sandstone and shale , and includes a large number of geologic formations ( United States Geological Survey [ USGS ] 1997)

. Runoff from the site drains via two drainage routes toward Caulk’s Creek , approximately 0.5 mile southwest of the site

. The depth to the water table was observed through multiple static water level

measurements taken from the three monitoring wells located on site, with measurements ra nging from 78 to 124 feet below ground surface ( Missouri Department of Natural Resources [ MDNR ] 2012)

. The Ozark Plateaus aquifer system extends throughout most of southern Missouri and consists of three aquifers separated by two confining units, all in co nsolidated rocks of Paleozoic age. The uppermost aquifer is in Mississippian carbonate rocks; stratigraphically equivalent carbonate rocks in northern Missouri are called the “ Mississippian aquifer. ” The middle aquifer of the Ozark Plateaus aquifer syste m is in carbonate rocks of Cambrian and Ordovician age, and the lowermost aquifer in the system is in Cambrian sandstones. The confining units that separate the aquifers are dolomite and shale. Water in the Ozark Plateaus aquifer system is unconfined in and just downgradient of aquifer outcrop areas but is confined elsewhere (USGS 199 7 ).

Groundwater in the Ozark Plateaus aquifer system locally moves from topographically high recharge
areas to lower discharge areas such as streams. Regional movement is no rthwestward, eastward, and southward from the St. Francois Mountains and other topographically high areas in southern Missouri (USGS 199 7 ).

3.0 SITE HISTORY/ PREVIOUS INVESTIGATIONS
In August 1980, MDNR received a report of illegal dumping at the Callahan Prope rty site. A followup investigation revealed a disposal area of approximately 150 by 150 feet, containing buried drums and possibly other waste materials. During further investigations, several drums were unearthed and sampled. These activities determine d the drums contained paint

- related wastes and solvents. MDNR subsequently requested assistance from EPA Region 7 to address the buried drums, and an RA was immediately initiated. The RA occurred from December 1981 through February 1982, when 1,205 drums were removed from the disposal area. Of these, 613 were overpacked and staged in two areas of the site for off

- site disposal. Approximately 500 cubic yards of excavated soil was returned to the former drum burial area as backfill ( Tetra Tech EM Inc. 200 5 ).
Since the RA, followup investigations at the site have addressed public concerns regarding residual contamination, including an investigation by Black & Veatch Engineers

–Architects ( Black & Veatch ) in December 1982. This investigation included sampl ing of soils from the former drum burial and storage areas, and collection of surface water samples downgradient of those areas. Analytical results from these samples did not indicate any significant contamination (Black & Veatch 1983). A Phase II Enviro nmental Site Assessment (ESA) by Brucker Engineering, Ltd., in 1999, included a magnetometer survey and exploratory trenching in the burial area, drum storage areas, and drainage routes downgradient

### X9004.1 2 .0 316 .000

of the burial area. No significant contamination was ide ntified during the ESA (Brucker Engineering, Ltd. 1999). However, because of the limited scope of these investigations and apparent gaps in the data, the City of Wildwood, on behalf of the local residents, requested a more comprehensive study to determine whether any contamination remained at the site ( Tetra Tech EM Inc. 2005 ).
From January 31 through February 2, 2005, Tetra Tech START performed a magnetometer survey and monitored site activities for a Removal Site Evaluation (RSE) conduct ed by MDNR ―including sampling of soil, sediment, and interior dust

. The purpose of the RSE was to determine whether any residual contamination remained at the site that warranted further Superfund response, following the RA conducted in 1981

- 1982. Based on analytical res ults from samples collected during the investigation, elevated levels of lead, semi

- volatile organic compounds ( SVOC ) , and VOCs were identified in subsurface soils at the former drum burial area (Tetra Tech EM Inc. 2005).

4.0 REMOVAL ACTIVITIES

EPA

- funded remo val activities were conducted at the site from November 12 through early December 2012 , by Environmental Restoration LLC (ER), the EPA Region 7 Emergency and Rapid Response Services (ERRS) contractor. Photographic documentation of the site activit ies is i n Appendix B. RA activities included removal and disposal of contaminated soil, backfilling excavated

areas , and site restoration. Summaries of analytical results for samples collected during the RA are included in tables in Appendix C.

4.1 SOIL EXCAVATION A ND DISPOSAL
Prior to excavation, a composite soil s ample was collected from the site by START on November 12, 2012, for full Code R analyses , including the Toxicity Characteristic Leaching Procedure (TCLP) . These data would be evaluated to ensure the soil was suitable for disposal at a municipal solid waste landfill . Th e sample was collected from hand

- dug test pits and an existing stockpile. START used shovels to dig five test pits to depths of approximately 2 feet below ground surface in the area to be excavated. A stainle s s steel spoon was used to collect aliquots of soil from three depths in each test pit. In addition, four aliquots of soil were collected from the stockpile at equally spaced intervals. All of these aliquots were placed in a disposab le Ziplock bag and homogenized

. The composite sample was homogenized and transferred to a 32

- ounce jar with proper labeling , and then ER submitted the sample to Teklab, Inc. for analysis. The analytical results were provided to the Milam Landfill in East St. Louis, Illinois, and the soil was determined acceptable for disposal at their facility.

### X9004.1 2 .0 316 .000 

## 4

Excavation of contaminated soil occurred at the site from November 27 through December 6, 2012

. ER used a Case CX210C hydraulic excavator to remove the contaminat ed soil, and up to seven dump trucks were used to transfer the excavated soil from the site to the Milam Landfill. During excavation, START monitored the extent of soil contamination by obtaining real

- time readings for VOCs using a photoionization detecto r ( PID ) , and for metals (lead in particular) using a n XRF spectrometer , once visual indications of contamination w ere no longer observed

. The XRF readings for lead from the west wall ranged from non

- detect to 8,302 parts per million ( ppm ) in an area of dark gray staining. As excavation of the west wall continued ( due to the elevated lead levels ) , liquid was observed draining from the wall. PID readings directly above the liquid reached 109 ppm. During further screening of the west wall, an additional ar ea of high lead levels (437 to 2,154 ppm) was observed, with VOC readings of approximately 400 ppm. PID readings from the east wall ranged from 0 to 0.5 ppm. The XRF readings for lead from the east wall ranged from less than 36 to 1,004 ppm. The final e xcavated area was approximately 21 feet long on the south, 75 feet on the east, 70 feet on the north, and 82 feet on the west. The depth of the excavated area ranged from 5 to 15 feet.

The PID was also used for real

- time air monitoring to ensure VOCs gene rated during the excavation activities did not reach levels above acceptable criteria with in both the area immediately surrounding the excavation pit , as well as along the site perimeter adjacent to residential propertie s bordering the site. A DataRAM aer osol monitor was also used for real

- time air monitoring for particulate matter

. PID readings ranged from 0 to 8.7 ppm within areas immediately surrounding the excavation pit, and from 0 to 1.5 ppm along the site perimeter near residential properties. Dat a RAM readings were all less than 30 micrograms per cubic meter (μg/m 3 

## ) near the excavation zone

— only slightly above background readings of approximately 10 to 20 μg/m 3



## . A personal air sampler was also used to measure lead concentrations in the breathing z one of workers during excavation activities ( sample CA

- PERAIR

- Pb)

. Elevated levels of lead in the breathing zone were not observed. The concentration of lead observed on the filter sample was < 0.00039 milligrams per cubic meter ( mg/m 3 

## ). A copy of the a nalytical results is in Appe ndix D.
During the excavation process, an attempt was made to remove a previously installed 91

- foot

- deep monitoring well (MW

- C01) from the excavation area. After multiple attempts to remove the well, the polyvinyl chloride (PVC ) riser pipe was cut off and the well was plugged to preclude entry of contaminated soil into the well that could reach the water table. The plugging occurred in stages. First, approximately 35 pounds (lbs) of medium bentonite chips was added to the well and topped with 4 gallons of water. Then, another 35 lbs of medium bentonite chips was added to the well and topped with 2 gallons of water, followed by an additional 15 lbs of bentonite and 2 gallons of water to completely fill the well.

- 02)

. The south wall s ample, CA

- SW

- 01, was collected from the entire length of the wall, which was approximately 21 feet long and 6 feet deep

. The highest PID reading at the south wall at the time of sampling was 0.6 ppm, and XRF readings for lead ranged from 86 to 277 ppm. A sample from the southern portion of the east wall ( CA

- EW

- 01 ) was collected within an area approximately 45 feet long and 5 to 10 feet deep , and a sample from the northern portion of the east wall ( CA

- EW

- 02 ) was collected within a n area approximately 30 fe et long and 10 to 15 feet deep. The highest PID reading within the area sampled as CA

- EW

- 01 was 0.5 ppm, and XRF readings for lead ranged from 55 to 908 ppm. VOCs were not detected via the PID with in the area sampled as CA

- EW

- 02, and XRF readings for lea d ranged from 54 to 192 ppm. A sample from the southern portion of the west wall ( CA

- WW

- 01 ) was collected within a n area approximately 32 feet long and 5 to 10 feet deep , and a sample from the northern portion of the west wall ( CA

- WW

- 02 ) was collected within a n area approximately 50 feet long and at a depth of approximately 10 feet. The highest PID reading within the area sampled as CA

- WW

- 01 was 2.0 ppm, and XRF readings for lead ranged from 34 to 395 ppm. The highest PID reading within the area sampled as CA

- WW

- 02 was 0.6 ppm, and XRF readings for lead ranged from 40 to 413 ppm. A sample from the western portion of the north wall ( CA

- NW

- 01 ) was collected within a n area approximately 45 feet long and 5 to 12 feet deep , and a sample from the eastern porti on of the north wall ( CA

- NW

- 02 ) was collected within a n area approximately 25 feet in length and 3 to 12 feet deep. VOCs were not detected via the PID with in the area sampled as CA

- NW

- 01, and XRF readings for lead ranged from 73 to 272 ppm. VOCs
were not detected via the PID with in the area sampled as CA

- NW

- 02, and XRF readings for lead ranged from less than 34 to 157 ppm.

The s oil samples were collected from the excavation for laboratory confirmation analysis. One grab sample was collected from the so uth wall, and two grab samples were collected from each remaining wall of the excavated area, following EPA Method 5035 for analysis for VOCs

. This involve d placing approximately 5 grams of soil into two 40

- milliliter (mL) volatile organic analysis (VOA) vials pre
- preserved with sodium bisulfate , and packing an additional laboratory

- supplied container with soil for determination of percent solids

. In addition, one five

- aliquot composite sample was collected from the south wall, and two five

- aliquot compos ite samples were collected from each remaining wall of the excavated area using disposable stainless steel spoons. Aliquots for each post

- excavation soil sample

### X9004.1 2 .0 316 .000 

## 6

were collected at various elevations from the walls of the excavation pit, including two aliqu ots from the top, one aliquot from the middle, and two aliquots from the bottom of each wall section

. ( The bottom of the pit was excavated to bedrock; therefore, no post

- excavation samples of the floor of the pit were collected

. ) The composite samples we re homogenized in disposable Ziplock bags and placed in 8

- ounce jars for analyses for SVOCs , RCRA metals , and polychlorinated biphenyl s ( PCB )

. All soil samples were stored in coolers and submitted to TestAmerica laboratory in Earth City , Missouri , or Tekl ab, Inc. in Collinsville, Illinois , on the day these were collected

.
O ne sample of stained soil that had an odor (CA

- SOIL

- 01) was collected from the floor of the excavation pit along the west wall

. The grab sample was analyzed for VOCs and SVOCs. The h ighest PID reading for VOCs i n this area of the pit was 8.4 ppm. A PID reading of 82.5 ppm was detected in t he headspace of a sample jar containing the soil sample for analysis for SVOCs

. XRF readings of the soil sample for lead were all below 70 ppm.

Overburden removed from the top, western portion of the excavation area was stockpiled for use as backfill material. The overburden was screened with the PID and XRF spectrometer , and sampled (CA

- OVRSTK

- 01) for analy ses for VOCs and SVOCs. All PID readin gs were 0 ppm, and XRF readings ranged from 124 to 415 ppm. The sample to be analyzed for VOCs was collected (in accordance with EPA Method 5035) from the stockpile after the surface soil had been removed and placed into VOA vials pre
- preserved with sodiu m bisulfate

. Additional s oil was placed in another container for determination of percent solids

. A seven

- aliquot composite sample for SVOCs analysis was also collected from inside the stockpile with a shovel , placed into a disposal Ziplock bag, homogeni zed, and transferred to an 8

- ounce jar

. Analytical results for all soil samples were compared to EPA RSL s . All results were below RSL s except those for arsenic in the walls of the excavation pit. However, all arsenic results were below the average

concen tration of 10.561 ppm for St. Louis County soils (USGS 2012). Appendix C summarizes all soil sample results, and Appendix D includes the complete laboratory data submittals

. Excavation of contaminated soil was completed on December 6, 2012

. In all, 2,0 56.74 tons of contaminated soil and debris , including drum fragments and metal pieces , was excavated and transported
to the Milam Landfill in East St. Louis, Illinois, for proper disposal as “ special waste. ” The landfill accepted the waste based on dispos al characterization sampling results (from November 2012 ), which had indicated that contaminated soil at the site did not contain hazardous constituents above acceptable levels

or leach constituents above corresponding regulatory TCLP limit s
.

4.2 BACKFILLING A ND SITE RESTORATION
Following completion of excavation, site activities shifted to backfilling and site restoration. One grab sample of backfill material (CAL

- BF

- 1) was collected by ER , and one grab sample of off

- site topsoil (CA

- TPSL

- 01) was collected by Tetra Tech , to confirm the se did not contain contaminants above levels of concern

. Those samples were analyzed for VOCs, SVOCs , and RCRA metals

. The backfill and topsoil samples did not contain any contaminants above RSLs e xcept for arsenic. However, a ll arsenic results were below the average concentration of 10.561 ppm for St. Louis County soils (USGS 2012)

. Therefore, the pit was filled with stockpiled overburden from the excavated area, off

- site backfill soil, and topsoil.
Following completion of backfilling , the site w as restored in accordance with agreements betw een EPA and the property owner

. T he excavated area was completed with a swale that in cluded rip rap to serve as a drainage route , while the remaining portion of the site property was res tored by hydroseeding. The swale was approximately 8 feet wide by 150 feet long, and the rock used for rip rap was 6

- to 8

- inch Gabien s tone. Following completion of site restoration activities, the removal action was considered complete.

5.0 SUMMARY

EPA t asked Tetra Tech START to provide RA support at the Callahan Property site in Wildwood, Missouri , where contaminated soils had been identified. The Callahan Property site is a sub

- site of the Ellisville Superfund site. The RA was conducted to address con taminated soil associated with buried drums previously removed from the site

. Illegal burial of the drums and possibly other waste materials ha d been identified in previous investigations as the likely source of soil contamination at the Callahan Property site

.
Excavation of contaminated soil occurred at the site from November 27 through December 6, 2012 . A total of 2,056.74 tons of contaminated soil was excavated and transported to the Milam L andfill in East St. Louis, Illinois , fo r proper disposal

. S oil samples were collected from perimeter walls of the excavated

area for laboratory analysis to confirm that cleanup goals had been achieved. These included o ne sample from the south wall, and two samples from each of the east, west, and north walls. Th e bottom of the pit was excavated to bedrock; therefore, no post

- excavation samples of the floor of the pit were collected

. All po st

- excavati on samples , as well as an overburden stockpile sample, stained and odiferous soil sample, and off

- site backfill an d topsoil samples, contained concentrations of hazardous constituents below corresponding RSLs , except for arsenic. However, the arsenic concentrations were below the

### X9004.1 2 .0 316 .000 

## 8

average concentration of arsenic in St. Louis County soils (USGS 2012)

. Removal activit ies were completed in mid

- December 2012 , after site restoration activities had been completed in accordance with agreements between EPA and the owner of the site propert y
.
5.1 REMOVAL CONSIDERATIONS

The RA described in this report involved excavation and pro per disposal of 2,056.74 tons of contaminated soil as special waste

. Because the primary source of contaminated soil (buried drums/wastes) had been removed during previous site activities, and th is RA involved remov al of contaminated soil associated with the buried wastes , no conditions are known to exist that would warrant further removal activities

.
5.2 PRE
- REMEDIAL CONSIDERATIONS

Pre

- remedial issues have been evaluated in previous site assessment reports completed by MDNR and contractors for EPA

. Other than removing contaminated soil from the source area, no activities were conducted during the RA, and no new information was obtained that would likely impact previous pre

remedial determinations regarding the Callahan Property site.

## Abbr Definition CCV Continuing calibration verification is a check o f a standard to determine the state of calibration of an instrument between recalibration. DF Dilution factor is the dilution performed during analysis only and does not take into account any di lutions made during sample preparation. The reported result is final and includes all dilutions factors. DNI Did not ignite DUP Laboratory duplicate is an aliquot of a sample t aken from the same container under laboratory condi tions for independent processing and analysis independently of the original aliquot. ICV Initial calibration verification is a check of a standard to determine the state of calibration of an instrument before sample analysis is initiated. IDPH IL Dept. of Public Health LCS Laboratory control sample, spiked with verified known amounts of analytes, is analyzed exactly like a sample to establish intra-laboratory or analyst specific precision and bias or to assess the perfor mance of all or a portion of the measurement system . The acceptable recovery range is in the QC Package (provided upon request). LCSD Laboratory control sample duplicate is a replic ate laboratory control sample that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery rang e is listed in the QC Package (provided upon reques t). MB Method blank is a sample of a matrix similar to t he batch of associated sample (when available) that is free from the analytes of interest and is processed simultaneously with and under the same co nditions as samples through all steps of the analyt ical procedures, and in which no target analytes or interferences should present at concent rations that impact the analytical results for samp le analyses. MDL Method detection limit means the minimum concent ration of a substance that can be measured and repo rted with 99% confidence that the analyte concentration is greater than zero and is determine d from analysis of a sample in a given matrix type containing the analyte. MS Matrix spike is an aliquot of matrix fortified (s piked) with known quantities of specific analytes t hat is subjected to the entire analytical procedure s in order to determine the effect of the matrix on an a pproved test method’s recovery system. The acceptab le recovery range is listed in the QC Package (provided upon request). MSD Matrix spike duplicate means a replicate matrix spike that is prepared and analyzed in order to det ermine the precision of the approved test method. The acceptable recovery range is listed in the QC P ackage (provided upon request). MW Molecular weight ND Not Detected at the Reporting Limit NELAP NELAP Accredited PQL Practical quantitation limit means the lowest le vel that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operation conditions. The acceptable rec overy range is listed in the QC Package (provided u pon request). RL The reporting limit the lowest level that the dat a is displayed in the final report. The reporting limit may vary according to customer request or sam ple dilution. The reporting limit may not be less than the MDL. RPD Relative percent difference is a calculated diff erence between two recoveries (ie. MS/MSD). The acc eptable recovery limit is listed in the QC Package (provided upon request). SPK The spike is a known mass of target analyte adde d to a blank sample or sub-sample; used to determin e recovery deficiency or for other quality control purposes. Surr Surrogates are compounds which are similar to t he analytes of interest in chemical composition and behavior in the analytical process, but which are not normally found in environmental samples. TNTC Too numerous to count ( > 200 CFU ) 

## Qualifiers # - Unknown hydrocarbon B - Analyte detected in associated Method Blank E - Value above quantitation range H - Holding times exceeded J - Analyte detected below quantitation limits M - M anual Integration used to determine area response ND - Not Detected at the Reporting Limit R - RPD outside accepted recovery limits S - Spike Recovery outside recovery limits X - Value exceeds Maximum Contaminant Level

## DATA VALIDATION QUALIFIERS

U

— The analyte was analyzed for, but was not dete cted above the reported sample

quantitation limit.
J

— The analyte was positively identified; the associated numerical value is the approximate

concentration of the analyte in the sample.
UJ

— The analyte was analyzed for, but was not detected above the reported sample

quantitation limit, which is estimated.
R

— The sample results are rejected due to serious deficiencies in the ability to analyze the

sample and meet quality control criteria. The presence or absence of the analyte cannot be verified.103DI9004L 120316 000

- 1, 160

- 981

- 1, and 160

- 1 included seven environmental soil sample s
. Samples were analyzed for volatile organic compounds (VOC) by EPA Method 8260B , semivolatile organic compounds ( SVOC ) b y EPA Method 82 70C , polychlorinated biphenyls (PCB) by EPA Method 8082A, an d metals by EPA Methods 6010B , 7470A, and 7471 A

. All samples did not receive all analyses. The following summarizes the data validation that was performed.

VOLATILE ORGANIC COMP OUND ANALYSIS
I. Holding Time and Chain of Custody (COC) Requirements All samples were received by the laboratory and analyzed within the established holding time of 14 days from sample collection to analysis. Some soil samples were received by the labo ratory at near ambient temperature due to the short time between collecti on and arrival , but the samples were promptly analyzed. No anomalies were found with the COC. No data were qualified.
II. Matrix Spike/Matrix Spike Duplicate (MS/MSD) MS/MSD analy ses were performed on sample CAL

- BF

- 1 and samples from other sites. All recoveries and RPDs were within established control limits. No data were qualified.
III. Blanks No analyte s were found in most of the laboratory (method) blanks or in the trip blan k

. One laboratory blank contained low concentrations of methylene chloride and tetrachloroethene. Neither compound was detected in any associated sample, so n o data were qualified

. IV. Laboratory Control Sample (LCS)
Percent recoveries for the LCS a nal yses (and RPD for duplicate LCS used, at times, in lieu of MS/MSD analyses) were within established control limits with no exception s
. No data were qualified

. V. Surrogates
Most surrogate recoveries were within established control limits. However, samp les CA

- SW

- 01, CA

OVRSTK

- 01, and CA

- WW

- 01 yielded excessive recoveries of one of the four surrogates, 4

- bromofluorobenzene. In addition, sample CA

- SOIL

- 01 yielded excessive recoveries of most of the surrogates during initial analysis, re

- analysis, and dilu ted re

- analysis. All of these high recoveries are due to matrix interference from the many VOC in the samples. Therefore all results from samples CA

- SW

01, CA

- SOIL

- 01, CA

- OVRSTK

- 01, and CA

- WW

- 01were qualified as estimated and flagged “J” or “UJ”, as appr opriate.
VI. Comments Some positive results were above the sample detection limit but less than the sample reporting limits ( “RL” in the laboratory reports) , which correspond to the lowest calibration standard. The laboratory correctly flagged these res ults “J” to indicate that they are estimated. In addition, sample CA

## was re
- analyzed at a 20

- fold dilution to bring the concentration of toluene down within calibration range. This succeeded, so no further qualifications are required.
VII. Overa ll Assessment of Data Overall data quality is acceptable, with few qualifications applied . All data are usabl e as qualifi ed for their intended purposes

.

SEMIVOLATILE ORGANIC COMPOUND ANALYSIS
I. Holding Time and Chain of Custody (COC) Requirements
A ll samples were received by the laboratory and analyzed within the established holding time of 14 days from sample collection to extraction and 40 days from extraction to anal ysis. No anomalies were found with the COC. No data were qualified.
II. Matrix Spike/Matrix Spike Duplicate (MS/MSD)
Soil MS/MSD analyses were performed on sample s CAL

- BF

- 1, and CA

- SW

- 01

. M ost r ecoveries and RPD were within their established control limit s
. However, the MS/MSD analys es performed on sample CA

- SW

- chloroaniline, 3

- nitroaniline, and 4

- nitroaniline. The results for bis(2

## POLYCHLORINATED BIPHENYL COMPOUND ANALYSIS
I. Holding Time and Chain of Custody (COC) Requirements All samples were received by the laboratory and analyzed within the established holding time of 14 days from samp le collection to extraction and 40 days from extraction to analysis. No anomalies were found with the COC. No data were qualified.
II. Matrix Spike/Matrix Spike Duplicate (MS/MSD) Soil MS/MSD analyses were performed on sample CA

- SW

- 01. All recoveries and RPD were within their established control limits.
III. Blanks No target analytes were detected in the method blank. No qualifications were applied.
IV. Laboratory Control Sample (LCS)
Percen t recoveries for the LCS analysi s were within establish ed control limits with no exceptions. No qualifications were applied.
V. Surrogates Almost all surrogate recoveries were within established control limits. The sole exception was a slightly high recovery on column 1 for the one surrogate in the MS samp le

. The recoveries from both columns for the unspiked sample and the MSD sample were within control limits, as was the recovery on column 1 for the MS sample. All results were quantitated from column 1, so no qualifications were applied for this minor i rregularity in a QC sample.
VI. Comments
One of the few positive results w as above the sample detection limit but less than the sample reporting limit (“RL” in the laboratory reports), which correspond to the lowest calibration standard. The laboratory correctly flagged th is result “J” to indicate that it is estimated. All samples with positive results were identified as containing Aroclor 1260; most also contained some Aroclor 1248. Data users should note that the constituents of those mixtures over lap, so the total PCB concentration is not fully certain. In addition, a different analyst may make a different identification of the mixtures present, which would result in different quantitative results. Th e true total PCB concentrations may be higher or lower than what is reported here; only analysis for PCB as congeners can provide fully definitive results. In addition, it is possible that all the PCB detectable in these samples are actually Aroclor 1260 degraded to various degrees.
VII. Overal l Assessment of Data Overall data quality is acceptable, with no data rejected. No qualifications were applied. All data are usable as report ed for their intended purposes.103DI9004L 120316 000

## METALS ANALYSIS
I. Holding Time and Chain of Custody (COC) Requirements
Al l samples were received by the laboratory and analyzed within the est ablished holding time of 6 months (28 days for mercury) from samp le collection to analysis. No anomalies were found with the COC. No data were qualified.
II. Matrix Spike/Matrix Spike Duplicate (MS/MSD)
Metals MS /MSD analyses were performed on sample s CAL

- BF

- 1, CA

- SW

- 01, and CA

- WW

- 01, and samples f rom other sites

. Most recoveries and RPD were within established limits. Some exceptions involved the MS/MSD analyses performed on sample CA

- SW

- 01. Recoveries of lead were 70 and 102 percent, versus established control limits of 75 to 125 percent. These irregularities are probably due to a somewhat irregular distribution of the lead within the soil, which is common when lead contamination is distributed as particles. The average recovery and the relative percent difference (RPD) between the results were well within control limits, so no qualifications were applied for this minor irregularity.
The other exceptions involved the MS/MSD anal yses performed on sample CA

- WW

- 01. First, the unspiked sample contained about 6.5 times the lead of the added spike, so recoveries of lead could not be reliably det ermined. No qualifications were applied for this data gap. However, RPD between the MS an d MSD results for lead was 89 percent, far above the laboratory’s limit of 30 percent. In addition, the recoveries of barium were 76 and 34 percent and those for chromium were 89 and negative percent, all versus established limits of 75 to 125 percent rec overy. These irregular recoverie s led to excessive RPD, also. A ll of these irregularities are due to heterogeneity in the distribution of the affected metals within the soil from that location. Therefore the results for lead, barium, and chromium in sample CA

- WW

- 01 were qualified as estimated and flagged “J”.
III. Blanks
Most laboratory (method) blanks contained no detectable metals

. However, one contained a low concentration of lead and another a low concentration of mercury. In both cases the acc ompanying samples contained much higher concentrations of the metals so no qualifications were applied.
IV. Laboratory Control Sample (LCS) Percent recoveries for the LCS analyses were within established control limits. No data were qualified.
V. Comments Some results were analyzed at a dilution due to matrix interference, which raised detection limits. No qualifications were applied. Some positive results were above the sample detection limit but less than the sample reporting limits (“RL” in the l aboratory reports), which correspond to the lowest calibration standard. The laboratory correctly flagged these results “J” to indicate that they are estimated.
VII. Overall Assessment of Data103DI9004L080098000 

### 7 SDG F 8E270182



## Overall dat a quality is acceptable, with some qualificatio n s fo r irregular distributions of some metals within the soil . All data are usable as qualifi ed for their intended purposes.

The data were qualified according to the U.S. Env ironmental Protection Agency (EPA) Region 7 documents entitled "Contrac t Laboratory Program National Functional Guidelines for Superfund Organic Methods Data Review " ( 9240.1

- 48 , June 200 8 and “Contract Laboratory Program National Functional Guidelines for Inorganic Superfund Data Review ” ( 9240.1

- 51 , January 2010 ). In addition, the Tetra Tech document “Review of Data Packages from Subcontracted Laboratories” (February 2002) was used along with other criteria specified in the applicable methods.
The review was intended to identify problems and quality control (QC) deficiencies that were readily apparent from the summary data package. The following sections discuss any problems or deficiencies that were found, and data qualifications applied because of non

- c ompliant QC. The data review was limited to the available field and laboratory QC information submitted with the project specific data package. I, Harry Ellis , certify that all data validation criteria outlined in the above referenced documents were asse ssed, and any qualifications made to the data were in accordance with those documents.

## DATA VALIDATION QUALIFIERS

E

— The analyte was positively identified; however, the value is above the quantitation range

. J

— The analyte was positively identified; the associated numerical value is the approximate

concentration of the analyte in the sample because the analyte was detected below quantitation limits

. S

— The Spike Recovery was outsid e recovery limits.103DI9004L 120316 000 

### 3 SDG 12120260 and 1212041 5 

## DATA ASSESSMENT

Sample delivery group s (SDG) 12120260 and 12120415 included four environmental soil sample s and one (1) aqueous quality control (QC) sample ( a trip blank)

. Samples were analyzed for volatile organic compounds (VOC) by EPA Method 8260B , semivolatile organic compounds ( SVOC ) by EPA Method 82 70C , polychlorinated biphenyls (PCB) by EPA Method 8082A, an d metals by EPA Methods 6010B and 7471 A

. The following summarizes the data validation that was performed.

VOLATILE ORG ANIC COMPOUND ANALYSIS
I. Holding Time and Chain of Custody (COC) Requirements All samples were received by the laboratory and analyzed within the established standard holding time of 14 days from sample collection to analysis. Some samples were receive d at ambient temperature on the day of collection . They were analyzed the next day, well within the 7 day holding time for unpreserved samples so n o data were qualified. No anomalies were found with the COC.
II. Matrix Spike/Matrix Spike Duplicate (MS/M SD)
No MS/MSD analyses were performed

. The duplicate LCS analyses provided adequate informati on on accuracy and precision so no qualifications were applied for this data gap.
III. Blanks No analyte s were found in the aqueous laboratory (method) blank

. However, the soil laboratory blank yielded a low concentration of the common laboratory contaminant methylene chloride. The similar concentration in sample CA

- NW

- 01 is qualified as a laboratory artifact and flagged “U” to indicate that it was undetected. The somewhat larger concentrations of methylene chloride reported in samples CA

- EW

02 and CA

- NW

- 02 may be, in part, the laboratory contami nation so their concentrations we re qualified as estimated and flagged “J” to indicate that.
IV. Laboratory Control Sample (LCS)
Percent recoveries for the duplicate LCS a nalyses were within established control limits with one exception

. Both soil LCS yielded recoveries of acrolein of more than 200 percent, well above the QC limits. That analyte was not detected in any of the associated field samples, so no qualifications were applied.
V. Surrogates
Most surrogate recoveries were within established control limits. However , sample CA

- NW

- 01 yielded a recovery for one (of four) surrogates of 81 percent, below the lab oratory’s limits of 82 to 116 percent. This low recovery is apparently due to interference from the numerous VOC analytes in the sample. Therefore all VOC results for sample CA

- NW

- 01 were qualified as estimated and flagged “J” or “UJ”, as appropriate to indicate that.103DI9004L 120316 000 

### 4 SDG 12120260 and 1212041 5



## VI. Comments Some positive results were above the sample detection limit ( not listed in the laboratory reports) but less than the sample reporting limits ( “RL” in the laboratory reports) , which correspond to the lowest calibration standard . The laboratory correctly flagged these results “J” to indicate that they are estimated.
VII. Overall Assessment of Data Overall data quality is acceptable, with a few qualifications applied . All data are usable as qualifi ed for their intended purpo ses
.

SEMIVOLATILE ORGANIC COMPOUND ANALYSIS
I. Holding Time and Chain of Custody (COC) Requirements All samples were received by the laboratory and analyzed within the established holding time of 14 days from sample collection to extraction and 40 days from extraction to anal ysis. No anomalies were found with the COC. No data were qualified.
II. Matrix Spike/Matrix Spike Duplicate (MS/MSD)
Soil MS/MSD analyses were performed on sample s CA

- NW

- 02 and CA

- TPSL

- 01 and all results were within their establi shed control limit s
. No qualifications were applied.

. Blanks No target analytes were detected in the method blank s
. No qualifications were applied

. IV. Laboratory Control Sample (LCS) Percent recoveries for the LCS analyses were with in establishe d c ontrol limits with no exception s
. N o qualifications were applied.
V. Surrogates All surrogate recoveries were within established control limits with no exceptions

. No qualifications were applied.
V I

. Comments
Some of the positive results were ab ove the sample detection limit but less than the sample reporting limits (“RL” in the laboratory reports) , which correspond to the lowest calibration standard. The laboratory correctly flagged these results “J” to indicate that they are estimated.
VI I

. O verall Assessment of Data Overall data quality is acceptable, with no data rejected. No qualifications were applied. A ll data are usable as report ed for their intended purposes.103DI9004L 120316000 

### 5 SDG 12120260 and 12120415 

## POLYCHLORINATED BIPHENYLS ANALYSIS
I. Holding Time and Chain of Custod y (COC) Requirements All samples were received by the laboratory and analyzed within the established holding time of 14 days from sample collection to extraction and 40 days from extraction to analysis. No anomalies were found with the COC. No data were qualified.
II. Matrix Spike/Matrix Spike Duplicate (MS/MSD) MS/MSD analyses were performed on sample CA

- EW

- 02 . All recoveries and RPDs were within established control limits. No data were qualified.
III. Blanks No target analytes were detected in th e method blank. No data were qualified.
IV. Laboratory Control Sample (LCS) Percent recoveries for the LCS analyses were within established control limits. No data were qualified.
V. Surrogates
Most surrogate recoveries were within established contro l limits. The exception was the second surrogate in sample CA

- NW

- 02, with a recovery of 170 percent versus control limits of 5 to 156 percent. This irregularity is probably due to interference from the PCB detected in the sample. No further qualificatio ns were applied.
VI. Comments Some of the positive results were above the sample detection limit but less than the sample reporting limits (“RL” in the laboratory reports), which correspond to the lowest calibration standard. The laboratory correctly fl agged these results “J” to indicate that they are estimated.
VII. Overall Assessment of Data Overall data quality is acceptable, with no qualification s added . All data are usable as reported for their intended purposes.

METALS ANALYSIS
I. Holding Time and Chain of Custody (COC) Requirements All samples were received by the laboratory and analyzed within the est ablished holding time of 6 months (28 days for mercury) from samp le collection to analysis. No anomalies were found with the COC. No data were qualified.103DI9004L 120316 000

## Abbr Definition CCV Continuing calibration verification is a check of a standard to determine the state of calibration of an instrument between recalibration. DF Dilution factor is the dilution performed during analysis only and does not take into account any dilutions made during sample preparation. The reported result is final and includes all dilutions factors. DNI Did not ignite DUP Laboratory duplicate is an aliquot of a sample taken from the same container under laboratory conditions for independent processing and analysis independently of the original aliquot. ICV Initial calibration verification is a check of a standard to determine the state of calibration of an instrument before sample analysis is initiated. IDPH IL Dept. of Public Health LCS Laboratory control sample, spiked with verified known amounts of analytes, is analyzed exactly like a sample to establish intra-laboratory or analyst specific precision and bias or to assess the performance of all or a portion of the measurement system. The acceptable recovery range is in the QC Package (provided upon request). LCSD Laboratory control sample duplicate is a replicate laboratory control sample that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery range is listed in the QC Package (provided upon request). MB Method blank is a sample of a matrix similar to the batch of associated sample (when available) that is free from the analytes of interest and is processed simultaneously with and under the same conditions as samples through all steps of the analytical procedures, and in which no target analytes or interferences should present at concentrations that impact the analytical results for sample analyses. MDL Method detection limit means the minimum concentration of a substance that can be measured and reported with 99% confidence that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the analyte. MS Matrix spike is an aliquot of matrix fortified (spiked) with known quantities of specific analytes that is subjected to the entire analytical procedures in order to determine the effect of the matrix on an approved test method’s recovery system. The acceptable recovery range is listed in the QC Package (provided upon request). MSD Matrix spike duplicate means a replicate matrix spike that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery range is listed in the QC Package (provided upon request). MW Molecular weight ND Not Detected at the Reporting Limit NELAP NELAP Accredited PQL Practical quantitation limit means the lowest level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operation conditions. The acceptable recovery range is listed in the QC Package (provided upon request). RL The reporting limit the lowest level that the data is displayed in the final report. The reporting limit may vary according to customer request or sample dilution. The reporting limit may not be less than the MDL. RPD Relative percent difference is a calculated difference between two recoveries (ie. MS/MSD). The acceptable recovery limit is listed in the QC Package (provided upon request). SPK The spike is a known mass of target analyte added to a blank sample or sub-sample; used to determine recovery deficiency or for other quality control purposes. Surr Surrogates are compounds which are similar to the analytes of interest in chemical composition and behavior in the analytical process, but which are not normally found in environmental samples. TNTC Too numerous to count ( > 200 CFU ) 

## Qualifiers # - Unknown hydrocarbon B - Analyte detected in associated Method Blank E - Value above quantitation range H - Holding times exceeded J - Analyte detected below quantitation limits M - Manual Integration used to determine area response ND - Not Detected at the Reporting Limit R - RPD outside accepted recovery limits S - Spike Recovery outside recovery limits X - Value exceeds Maximum Contaminant Level

## Abbr Definition CCV Continuing calibration verification is a check of a standard to determine the state of calibration of an instrument between recalibration. DF Dilution factor is the dilution performed during analysis only and does not take into account any dilutions made during sample preparation. The reported result is final and includes all dilutions factors. DNI Did not ignite DUP Laboratory duplicate is an aliquot of a sample taken from the same container under laboratory conditions for independent processing and analysis independently of the original aliquot. ICV Initial calibration verification is a check of a standard to determine the state of calibration of an instrument before sample analysis is initiated. IDPH IL Dept. of Public Health LCS Laboratory control sample, spiked with verified known amounts of analytes, is analyzed exactly like a sample to establish intra-laboratory or analyst specific precision and bias or to assess the performance of all or a portion of the measurement system. The acceptable recovery range is in the QC Package (provided upon request). LCSD Laboratory control sample duplicate is a replicate laboratory control sample that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery range is listed in the QC Package (provided upon request). MB Method blank is a sample of a matrix similar to the batch of associated sample (when available) that is free from the analytes of interest and is processed simultaneously with and under the same conditions as samples through all steps of the analytical procedures, and in which no target analytes or interferences should present at concentrations that impact the analytical results for sample analyses. MDL Method detection limit means the minimum concentration of a substance that can be measured and reported with 99% confidence that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the analyte. MS Matrix spike is an aliquot of matrix fortified (spiked) with known quantities of specific analytes that is subjected to the entire analytical procedures in order to determine the effect of the matrix on an approved test method’s recovery system. The acceptable recovery range is listed in the QC Package (provided upon request). MSD Matrix spike duplicate means a replicate matrix spike that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery range is listed in the QC Package (provided upon request). MW Molecular weight ND Not Detected at the Reporting Limit NELAP NELAP Accredited PQL Practical quantitation limit means the lowest level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operation conditions. The acceptable recovery range is listed in the QC Package (provided upon request). RL The reporting limit the lowest level that the data is displayed in the final report. The reporting limit may vary according to customer request or sample dilution. The reporting limit may not be less than the MDL. RPD Relative percent difference is a calculated difference between two recoveries (ie. MS/MSD). The acceptable recovery limit is listed in the QC Package (provided upon request). SPK The spike is a known mass of target analyte added to a blank sample or sub-sample; used to determine recovery deficiency or for other quality control purposes. Surr Surrogates are compounds which are similar to the analytes of interest in chemical composition and behavior in the analytical process, but which are not normally found in environmental samples. TNTC Too numerous to count ( > 200 CFU ) 

## Qualifiers # - Unknown hydrocarbon B - Analyte detected in associated Method Blank E - Value above quantitation range H - Holding times exceeded J - Analyte detected below quantitation limits M - Manual Integration used to determine area response ND - Not Detected at the Reporting Limit R - RPD outside accepted recovery limits S - Spike Recovery outside recovery limits X - Value exceeds Maximum Contaminant Level

Client Name : Tetra Tech, Inc Site : Ellisville-Callahan Site Project No. : 103X9004L120316.000 6601 Kirkville Road East Syracuse, NY 13057 Date Sampled : 29-NOV-12 Account No.: 21870 (315) 432-5227 Date Received: 04-DEC-12 Login No. : L279555 FAX: (315) 437-0571 Date Analyzed: 05-DEC-12 www.galsonlabs.com

Unless otherwise noted below, all quality control results associated with the samples were within established control limits. Unrounded results are carried through the calculations that yield the final result and the final result is rounded to the number of significant figures appropriate to the accuracy of the analytical method. Please note that results appearing in the columns preceeding the final result column may have been rounded in order to fit the report format and therefore, if carried through the calculations, may not yield an identical final result to the one reported. The stated LOQs for each analyte represent the demonstrated LOQ concentrations prior to correction for desorption efficiency (if applicable). Unless otherwise noted below, reported results have not been blank corrected for any field blank or method blank. L279555 (Report ID: 762770):

The Lead results are considered accurate to within +/-6.6% based on a 95% confidence interval (k=2). This method has an average recovery of 98%. The estimated uncertainty applies to the media, technology, and SOP(s) referenced in this report and does not account for any uncertainty associated with the sampling process. Reported results reflect elemental analysis of the requested metals. Certain compounds may not be solubilized during digestion, resulting in data that is biased low. SOPs: MT-SOP-9(22), im-mwvfilt(17)
