MOM 2011 Annual Report

EXECUTIVE SUMMARY

This report presents the results of the sampling and analysis of the April 2011 annual groundwatermonitoring program conducted at the O’Connor Superfund Site (Site) in Augusta, Maine.

Representatives from Central Maine Power Company (CMP) and Woodard & Curran (W&C) performed

this work on April 21, 2011. The sampling was conducted in accordance with the sampling methodology

contained in the O’Connor Site Management of Migration (MOM) Groundwater Monitoring Program

Sampling and Analysis Plan (SAP) dated December 1996 (Revision 4) with amendments.

The O’Connor Site was the former location of salvage processes, including stripping and recycling

transformers that contained polychlorinated biphenyl (PCB)-laden oil. As a result of uncontrolled

releases of PCBs, lead, carcinogenic polynuclear aromatic hydrocarbons (cPAHs), and volatile organic

compounds (VOCs) at the Site, the Site was placed on the National Priorities List. Site remediation

conducted to date has included the installation and operation of a vacuum enhanced product recovery

(VER) system (1996-1997, 2001-2004, and 2006), Source Control (1996-1997), and ongoing passive oil

recovery from observation wells in the former transformer work area II (TWA II). Analytical results for

this sampling event and previous sampling events are summarized in this report. The groundwater

sampling and analysis results obtained during this sampling round will be used to supplement previous

groundwater data collected at the Site.

This report compares the April 2011 groundwater quality data to the groundwater performance standards

specified in the 2002 Record of Decision (ROD) Amendment and 2003 Statement of Work (SOW).

These performance standards are chemical-specific Applicable or Relevant and Appropriate

Requirements (ARARs) based on United States Environmental Protection Agency (USEPA) Maximum

Contaminant Levels (MCLs) and Maine Maximum Exposure Guidelines (MEGs). The purpose of these

comparisons is to evaluate the level of compliance with the clean up standards for the target compounds.

A review of the results of the April 2011 sampling and the historic groundwater data at the O’Connor Site

has led to the following conclusions and recommendations:

 There were no exceedances of groundwater performance standards for the eight VOCs analyzed

for in the MOM monitoring wells in April 2011. VOCs were detected in four out of nine wells

sampled and were well below the groundwater performance standards.

 The concentrations of 1,4-dichlorobenzene in groundwater in the MOM wells are trending

downward.

 PCBs were not detected in MOM monitoring wells in April 2011.

The amount of oil removed from the wells using the VER system has decreased steadily over time. In the

fall of 2006 the VER system was shutdown because the rate of oil recovery using passive recovery was

equal to or greater than with the VER system. The passive oil recovery program will continue on a

quarterly basis.

MOM 2011 Annual Report

1. INTRODUCTION

1.1 PURPOSE AND OBJECTIVES

This document is the annual Sampling and Analysis Report for the MOM component of the Remedial

Design/Remedial Action at the Site located in Augusta, Maine. The requirement for a long-term

groundwater quality-monitoring program was established by the USEPA in the ROD, December 27, 1989

for the Site. In 2002, a ROD Amendment was signed that revised the original remedy. The ROD

Amendment established a waiver of ARARs, federal and state drinking water standards, for a limited

portion of the Site (including the TWA II Area) on the basis of technical impracticability. The ROD

Amendment also revised the ARARs to include a total of eight VOCs and PCBs. The TI waiver applies

to these ARARs within the TI zone of the Site, shown in Appendix A. The 2003 SOW incorporates the

revised ARARs as groundwater performance standards.

The primary objective of this report is to document the April 2011 groundwater sampling event and

present the analytical results. Work was performed in accordance with the MOM SAP dated December

1996 (Revision 4) with amendments. This report satisfies the submittal requirements under Section I.3.b.

(1)(c) of the revised SOW dated October 20, 1994. There were no additional submittal requirements in

the 2003 SOW.

W&C assisted CMP in implementing the MOM water quality-monitoring program. Groundwater

samples were collected from the nine MOM monitoring wells listed below. The locations of these wells

are shown in Appendix A.

Groundwater Monitoring Wells

MW-104B MW-501 MW-507A

MW-106A MW-502 MW-508B

MW-106B MW-503 OW-201B

The groundwater data from these samples provide current groundwater quality data for the ongoing MOM

monitoring program. The April 2011 groundwater quality data has been compared with data collected

from previous groundwater monitoring events. This groundwater data set will be used to identify if any

areas of the Site are not currently meeting groundwater performance standards. In addition, this data will

be used to identify groundwater quality trends for each specific sampling location.

1.2 SUMMARY OF PREVIOUS GROUNDWATER INVESTIGATIONS

Two significant groundwater migration pathways have been identified at this Site during previous studies.

The till/bedrock interface is the primary migration pathway of contaminants. The secondary migration

route is within the fractures in the bedrock. The monitoring wells with an “A” designation and MW-501,

MW-502 and MW-503 monitor the primary till/bedrock migration pathway; whereas the monitoring

wells with a “B” designation monitor the fractured bedrock aquifer. For a more detailed discussion of the

current hydrogeologic understanding of the Site, refer to Section 2.4 of the Draft Proposed Final MOM

Remedy report (12/97) or the June 2002 TI waiver Evaluation Report.
Central Maine Power (222350) 1-2 August 2011

MOM 2011 Annual Report

A comprehensive evaluation of the available groundwater analytical data from the Site was completed in

August 1997. The results of the MOM comprehensive evaluation indicated that the contaminants were

not continuing to migrate in groundwater and the contaminant levels in groundwater were not increasing.

PCB’s had not been detected in any of the MOM monitoring wells from May 1996 through September

1997 and, therefore; PCBs were not believed to be mobile in the groundwater flow system. Continued

monitoring has proven that no PCBs are migrating in the groundwater monitored in the MOM monitoring

program. The groundwater data suggested that contaminants are not moving in the principle till/bedrock

migration pathway due to low hydraulic conductivity. For a complete summary of historic groundwater

analytical results, refer to the MOM Comprehensive Evaluation (June 1997). Additionally, the Draft

Proposed Final Management of Migration Remedy report also summarizes the existing contaminant

distribution at the Site.

Two groundwater-monitoring wells (MW-507A and MW-508B) were installed at the Site southeast of

TWA-II in October 1997. The location of these two wells is shown in Appendix A. These wells were

installed to evaluate the groundwater within the area of the previously identified bedrock trough. These

two wells monitor different depth, zones (overburden and bedrock) at the same location.

Monitoring well MW-507A is a shallow well and is screened (approximately 10-20 feet below the ground

surface) in the till soils immediately above the bedrock surface. Monitoring well MW-507A is

constructed with a bentonite seal above the screen to prevent the vertical migration of surface water into

the well. Monitoring well MW-508B is a bedrock well screened 32-42 feet below the top of the PVC

riser to monitor the groundwater in the bedrock flow system. The depth of the screen zone in MW-508B

was chosen based upon an inspection of the bedrock cores collected during the drilling. MW-508B is

constructed with bentonite chips and a bentonite grout seal above the screen so that only the bedrock

groundwater will be available to recharge the well during purging and sampling. The groundwater

recharge to this well is very slow indicating a bedrock aquifer with low hydraulic conductivity.

Three monitoring wells, MW-509A, MW-510A and MW-511A and a piezometer MW-512A, were

installed north and west of TWA-II in July 2001. These wells were installed to provide additional

monitoring points for groundwater quality and groundwater elevation in the MOM monitoring network.

Piezometer MW-512A was installed to gather additional groundwater elevation data from the site. These

wells and piezometer were decommissioned on September 2, 2008. Decommissioning activities are

detailed in the Monitoring Well Decommissioning Summary (October, 2008).

2. SAMPLING PROCEDURES

During the April 2011 sampling event, groundwater samples were collected from the nine MOM

monitoring wells at the Site. Prior to the sampling activities each day, a health and safety meeting was

conducted for the field personnel. Health & Safety topics specific to the O’Connor site were presented

and discussed. The health and safety meetings are documented in the field notes for each work day. The

April 2011 monitoring event was completed without a health and safety incident.

2.1 GROUNDWATER PURGING AND SAMPLE COLLECTION

The MOM groundwater monitoring wells were purged and sampled using low-flow purging and sampling

techniques on April 21, 2011. Two MOM monitoring wells (MW-104B, and OW-201B) were sampled

with Grundfos Redi-Flo2 dedicated submersible pumps. The other MOM monitoring wells were sampled

with a Masterflex or Geopump peristaltic pump and dedicated tubing. The depth to groundwater and total

depth of each well were measured at each well. The depth to groundwater and groundwater elevations are

included in Appendix B.

Turbidity, pH, specific conductance, dissolved oxygen and temperature measurements were collected

from each well at three to five minute intervals during well purging. Field parameters with the exception

of turbidity were measured in a YSI 600XL multi-meter with flow-through cell. Turbidity measurements

were made with a Hach turbidity meter. The field parameter instruments were calibrated prior to use on

each day of sampling. Calibration checks were conducted a minimum of two (2) times per day during the

sampling activities. After determining that the groundwater elevation stabilization and field parameter

stabilization criteria had been achieved according to the stabilization criteria outlined in the SAP, samples

were collected for VOC and PCB laboratory analysis. The samples were collected at the same flow rate

used during purging. The flow cell was disconnected prior to collecting the sample. The field data sheets

are included in Appendix C.

A duplicate sample, MW-106AD, was collected from monitoring well, MW-106A. A matrix spike and

matrix spike duplicate, MW-503MS and MW-503MSD were collected from MW-503. Other quality

control samples included a trip blank, a field blank (FB-1) and an equipment blank (EB-1). All of the

samples were stored in a cooler at approximately 4-6 degrees Celcius from the time of sample collection

until delivery to the laboratory. Information concerning the sample custody and sample analysis is

included in Appendix D.

There were no PID readings collected during the April 2011 sampling event.

The depth to groundwater measurements were made prior to the purging of the wells and during the well

purging. The depths to groundwater measurements are included in the field data record sheets and in

Appendix B.

An inferred overburden groundwater contour map has been produced for the shallow groundwater aquifer

from the April 2011 groundwater elevation data. The inferred overburden groundwater contour map

shows generally south-eastward groundwater flow. The map does not show small variations in

groundwater flow due to a limited number of monitoring points. The April 2011 overburden groundwater

contour map is included in Appendix E.

MOM 2011 Annual Report

2.2 FREE PRODUCT OIL MONITORING

Four observation wells (OW-202B, OW-204B, OW-301B and OW-302B), the Phase II VER system

recovery well (RW-101), and piezometer UM-1, are not included in the current MOM groundwater SAP.

Prior to 2007, these wells were previously monitored monthly, and then quarterly for groundwater

elevation and free product thickness as part of a MOM Free Product Oil (FPO) monitoring study. Two

observation wells OW-204B and OW-301B and piezometer UM-1 are no longer monitored as they were

decommissioned in September 2008.

The results of the December 1997 to April 2011 FPO monitoring are shown in Appendix F. In January

2011, measurable oil (0.05 feet) was removed from OW-202B. Between 2006 (decommissioning of the

VER system) and 2010, measurable oil was removed from the following wells:

 2010: 0.06 feet OW-202B, RW-101

 2009: 0.07 feet OW-202B

 2008: 0.02 feet OW-202B, RW-101

 2007: 0.15 feet OW-202B, RW-101

Prior to that, the last measurable amount of oil removed from RW-101 and OW-202B was 0.11 and 0.24

feet, respectively, removed during the VER in 2006. Occasional skim coats of oil were observed at OW302B in 2007 and 2008. Prior to that, OW-302B has been clear of free product, as have the other

decommissioned TWA-II wells OW-204B and OW-301B and piezometer UM-1.

The VER system was operated on the four observation wells and RW-101 during the following periods:

August to October 2001, August and September 2002, August to October 2003, August to September

2004 and August 2006. Oil thickness monitoring conducted at each well during the operation of the VER

system showed that a decreasing quantity was recovered: approximately 20 gallons of oil were recovered

by the VER in 2001, 7.4 gallons in 2002, 2.5 gallons in 2003, and about 0.3 gallons in 2004 and 2006.

The VER process recovered a low volume of oil-product (0.29 gallons) in 2006. The amount of oil

removed from the wells using the VER system has decreased steadily over time to minimal amounts. In

December 2006, the VER system was decommissioned because the rate of oil recovery using passive

recovery was equal to or greater than with the VER system. The passive oil recovery program is

continuing on a quarterly basis.

3. ANALYTICAL RESULTS

The April 2011 groundwater field data records, which record the field parameter measurements and field

observations during the groundwater purging as well as other information, are included in Appendix C.

Copies of the chain-of-custody forms and other laboratory information are included in Appendix D. The

analytical results of the April 2011 MOM groundwater-sampling event are included in Table 1 and the

laboratory report is included in Appendix G. The data storage and data management functions are being

conducted using GIS/KEY software. This program facilitates data management and data reporting.

1,3,5-trichlorobenzene had not been included in the original scope of work and was not included in the

original VOC analyses prior to September 2004. From September 2004 to April 2011, there have been no

detections of 1,3,5-trichlorobenzene in groundwater from any of the monitoring well samples collected.

This compound will continue to be included in the MOM monitoring in future sample events.

3.1 GROUNDWATER RESULTS FROM THE MOM MONITORING PROGRAM

Groundwater clean-up standards established in the 1989 ROD include total PCBs at 0.5 ug/L, benzene at

5 ug/L, and 1,4-dichlorobenzene at 27 ug/L. The 2002 ROD Amendment incorporated the Maine MEGs

for PCBs of 0.05 ug/L, and chemical-specific ARARs based on USEPA MCLs and MEDEP MEGs for

additional VOCs. These are established as groundwater performance standards in the 2003 SOW and are

listed in Table 1. The results of the April 2011 water quality monitoring indicate:

 PCBs were not detected at any MOM monitoring wells. The practical quantitation limit

(detection limit) for PCBs was lowered from 0.1 to 0.05 ug/L, to be able to detect PCBs down to

the Maine MEG of 0.05 ug/L.

 Benzene was not detected at any MOM monitoring wells.

 There were no exceedances of the performance standard for 1,4-dichlorobenzene (27 ug/L) in

MOM monitoring wells in April 2011. 1,4-dichlorobenzene was detected below the performance

standard in groundwater samples collected from two monitoring well locations; MW-104B, and

OW-201B, at concentrations of 0.8, and 3 ug/L, respectively.

 1,3,5-trichlorobenzene was not detected in the groundwater in the MOM monitoring wells in

April 2011.

 Other target VOCs were detected including 1,2,3-trichlorobenzene in MW-104B; 1,2-

dichlorobenzene in MW-104B, MW-501 and OW-201B; 1,3-dichlorobenzene in MW-104B,

MW-507A and OW-201B; and chlorobenzene in OW-201B. Concentrations were well below

associated performance standards in all samples.

 The individual VOC results in the groundwater from MW-106A, MW-106B, MW-502, MW-503,

and MW-508B, were all below the detection limit of 1 ug/L.

Quality control results associated with the April 2011 VOC and PCB data were reviewed to determine

representativeness and usability. A Tier II validation procedure in which tabulated results are reviewed

was used for this assessment. Based on the results of validation, qualifiers, if any, were added to sample

concentrations to identify potential bias or false positive results.
Central Maine Power (222350) 3-2 August 2011

MOM 2011 Annual Report

All quality control parameters were compliant for VOC results; therefore, no sample qualifiers were

applied. Trip, field and method blank results were non-detect for all target VOCs indicating that there

were no interferences from shipping and laboratory processing.

Percent recoveries of the surrogate tetrachloro-m-xylene (TCX) on one of two GC columns are below

control limits of 62-111 in samples MW-508B, MW-502 and OW-201B. The non-compliant percent

recoveries of TCX in these samples of 50, 59 and 58, respectively, indicate a potential slightly low bias.

Since PCB concentrations for these samples were taken from the second column that had compliant

recoveries of TCX, there was no impact on the sample data. The non-detected results for MW-508B,

MW-502 and OW-201B were reported unqualified.

The closing calibration verification had high responses for Aroclor 1016, Aroclor 1260 and tetrachloro-mxylene (TCX) on one column. These responses resulted in Percent Differences (%D’s) that were outside

method acceptance limits indicating a potential high bias. However, sample concentrations were taken

from the second column which had compliant continuing calibration results. Therefore, there was no

impact on the sample data, and Aroclor 1016 and Aroclor 1260 results were reported unqualified.

Percent recoveries of Aroclor 1260 in the laboratory control sample (LCS) are above the control limits of

62-104. However, because percent recoveries of Aroclor 1260 in the LCSD are within control limits,

there was no impact on sample data and the associated samples were reported unqualified.

Overall, the quality control results for VOC and PCB analyses are compliant and indicate that the

associated data are acceptable for monitoring groundwater conditions at the O’Connor Site.

3.2 COMPARISON WITH PREVIOUS MOM RESULTS

There have been no PCBs detected in MOM monitoring wells since September 2005 and from 2002-

2005, PCB concentrations ranged from 0.06-0.91 ug/L.

There have been no detections of the eight site-specific VOCs above groundwater performance standards

since September 2004, and between 2002-2004 the only VOCs to exceed performance standards were

1,2-dichlorobenzene and 1,4-dichlorobenzene. There have been no exceedances of the performance

standard for benzene (5 ug/L) in the MOM wells in the last twelve years.

There has been a significant improvement in meeting the performance standard for 1,4-dichlorobenzene at

the site. Concentrations of 1,4-dichlorobenzene in groundwater have been below the performance

standard (27 ug/l) since September 2003, when the performance standard was exceeded at two MOM

wells, MW-104B and OW-201B.

Prior to December 1997, the concentration of 1,4-dichlorobenzene in OW-201B was in the range of 42-57

ug/L. Between March 1998 and October 2003, the 1,4-dichlorobenzene concentration at MW-201B

decreased to 25-36 ug/L, except for 47 ug/L in May 2002. The concentration of 1,4-dichlorobenzene at

OW-201B in 2004-2006 ranged from 8-24 ug/L, 8-13 ug/L in 2007-2009 and 3 ug/l in both 2010 and

2011. A time series plot showing the historic concentrations of 1,4-dichlorobenzene for several wells is

shown in Appendix H and suggests that the concentration is decreasing.

The 1,4-dichlorobenzene concentrations at MW-104B were relatively stable at 20-33 ug/L from

December 1998 to September 2001 and the range was slightly higher at 28-44 ug/L between September

2002 and September 2003. The concentration of 1,4-dichlorobenzene at MW-104B in 2010 (15 ug/L)

was consistent with historic results between 2004-2009 (3-20 ug/L). The concentration of 1,4-

dichlorobenzene at MW-104B decreased to 0.8 ug/L in 2011. A time series plot showing the historic

concentrations of 1,4-dichlorobenzene for several wells is shown in Appendix H.

The VOC concentrations in groundwater at MW-106A and MW-106B have been relatively consistent

over the past five years. The VOC results for MW-106A have been non-detect since April 2005. From

April 2002-2005, the total VOC concentration at MW-106A decreased from 2 ug/L to less than the

quantitation limit. The total VOC concentration at MW-106B has decreased from 22.7 ug/L in April

2002 to not detected above the quantitation limit. MW-106B flows under artesian conditions most of the

year. MW-106A monitors the overburden aquifer at this location and flows under low artesian conditions

during periods of high groundwater.

In the area of MW-507A and MW-508B, historically the VOC concentrations have been higher in the

overburden groundwater (MW-507A) than in the bedrock groundwater (MW-508B). For the April 2011

sampling event, the total VOC concentration at MW-507A was estimated at 0.4 ug/L and was non-detect

at MW-508B. Monitoring well MW-507A is an overburden well located in a bedrock trough and

screened in the till/bedrock surface migration pathway where contaminated groundwater from the former

TWA source areas flows slowly in a southeasterly direction. These wells were placed at this location to

monitor VOC concentrations in the primary, till/bedrock migration pathway (MW-507A) and the

secondary bedrock migration pathway (MW-508B).

Monitoring wells MW-501, MW-502 and MW-503, are shallow wells located down gradient of MW104B and OW-201B. In April 2011, the concentration of VOCs at MW-501 was estimated at 0.2 ug/L
Central Maine Power (222350) 3-5 August 2011

MOM 2011 Annual Report

and concentrations of VOCs at, MW-502 and MW-503 were non-detect, which is consistent with historic

results.

4. CONCLUSIONS AND RECOMMENDATIONS

The April 2011 groundwater-sampling event was conducted in accordance with the current SAP and

Quality Assurance Project Plan (QAPP). The results of the April 2011 sampling and a review of historic

groundwater data at the O’Connor Site has led to the following conclusions and recommendations:

 There were no exceedances of groundwater performance standards for the eight VOCs analyzed

for in the MOM monitoring wells in April 2011. VOCs were detected in four out of nine wells

sampled and were well below the groundwater performance standards.

 The concentrations of 1,4-dichlorobenzene in groundwater in the MOM wells are trending

downward.

 PCBs were not detected in MOM monitoring wells in April 2011.

Following operation of the VER system in the fall of 2006, it was decommissioned because the rate of oil

recovery using passive recovery was equal to or greater than with the VER system. The passive oil

recovery program will continue on a quarterly basis.

The samples were logged in for the analyses specified on the chain of custody form. All 

problems encountered and resolved during sample receipt have been documented on the 

applicable chain of custody forms. 

We certifY that the test results provided in this report meet all the requirements of the NELAC 

standards unless otherwise noted in this narrative or in the Report of Analysis. 

Sample analyses have been performed by the methods as noted herein. 

Should you have any questions or comments concerning this Report of Analysis, please do not 

hesitate to contact your Katahdin Analytical Services Project Manager, Ms. Shelly Brown. This 

narrative is an integral part of the Report of Analysis. 

Organics Analysis 

The samples of work order SE2119 were analyzed in accordance with "Test Methods for 

Evaluating Solid Wastes: PhysicaVChemical Methods." SW-846, 2nd edition, 1982 (revised 

1984), 3rd edition, 1986, and Updates I, IT, ITA, and ill 1996, 1998 & 2004, Office of Solid Waste 

and Emergency Response, U.S. EPA, and/or for the specific methods listed below or on the 

Report of Analysis.

Sample SE2119-10 was used for the Matrix Spike (MS) and Matrix Spike Duplicate (MSD), as 

per client request. 

8260B Analysis 

There were no protocol deviations or observations noted by the organics laboratory staff for this 

analysis. 

8082 Analysis 

Samples SE2119-5, 7 and 8 had low recoveries for the surrogate TCX on channel A which were 

outside of the laboratory established acceptance limits. Since the recoveries for TCX on channel 

B and DCB on both channels were acceptable, the samples were not reextracted. 

The opening CV (file 7ED685) had a high response for TCX on channel A and a low response for 

Aroclor 1260 on channel B which resulted in %D's that were outside of the method acceptance 

limit of 15%. Since the responses were acceptable on the confirmation channels, the associated 

samples were not reanalyzed. 

The opening/closing CV (file 7ED700) had high responses for TCX and Aroclor 1016 on channel 

A and a low response for Aroclor 1260 on channel B which resulted in %D's that were outside of 

the method acceptance limit of 15%. Since the responses were acceptable on the confirmation 

channels, the associated samples were not reanalyzed. 

The opening/closing CV (file 7ED715) had high responses for TCX on both channels and a high 

response for Aroclor 1016 on channel A which resulted in %D's that were outside of the method 

acceptance limit of 15%. Since the Aroclor 1016 response was acceptable on the confirmation 

channel, the associated samples were not reanalyzed. The associated samples may be biased high 

forTCX. 

The closing CV (file 7ED730) had high responses for TCX and DCB on both channels and a high 

response for Aroclor 1016 on channel A which resulted in %D's that were outside of the method 

acceptance limit of 15%. Since the Aroclor 1016 responses were acceptable on the confirmation 

channel, the associated samples were not reanalyzed. The associated samples may be biased high 

for TCX and DCB. 

The LCS WG90706-2 had a high recovery for Aroclor 1260 which was outside of the laboratory 

established acceptance limits. Since the LCSD had acceptable recoveries, the associated samples 

were not reextracted. 

There were no other protocol deviations or observations noted by the organics laboratory staff.

PACKAGE 
Katahdin Analytical Services A0000002

KATAHDIN ANALYTICAL SERVICES -ORGANIC DATA QUALIFIERS 

The sampled date indicated on the attached Report(s) of Analysis (ROA) is the date for which a grab 

sample was collected or the date for which a composite sample was completed. Beginning and start 

times for composite samples can be found on the Chain-of-Custody. 

U Indicates the compound was analyzed for but not detected above the specified level. This 

level may be the Limit of Quantitation (LOQ)(previously called Practical Quantitation Level 

(PQL)), the Limit of Detection (LOD) or Method Detection Limit (MDL) as required by the client. 

* 

D 

E 

J 

Note: All results reported as "U" MDL have a 50% rate for false negatives compared to those 

results reported as "U" PQULOQ or "U" LOD, where the rate of false negatives is <1 %. 

Compound recovery outside of quality control limits. 

Indicates the_cesult was obtained. from analysis of a diluted.sample. Smmgate recoveries may 

not be calculable. 

Estimated value. This flag identifies compounds whose concentrations exceed the upper level 

of the calibration range of the instrument for that specific analysis. 

Estimated value. The analyte was detected in the sample at a concentration less than the 

laboratory Limit of Quantitation (LOQ)(previously called Practical Quantitation Limit (PQL)), but 

above the Method Detection Limit (MDL). 

or 

J Used for Pesticide/Aroclor analyte when there is a greater than 40% difference for detected 

concentrations between the two GC columns. 

B Indicates the analyte was detected in the laboratory method blank analyzed concurrently with 

the sample. 

N Presumptive evidence of a compound based on a mass spectral library search. 

A Indicates that a tentatively identified compound is a suspected aldol-condensation product. 

P Used for Pesticide/Aroclor analyte when there is a greater than 25% difference for detected 

concentrations between the two GC columns. (for CLP methods only).
