1.0 Introduction
ENSR Consulting and Engineering (NC), Inc. (ENSR) has prepared this report on behalf of JFD Electronics
Corporation and CMSS, Inc. for the JFD Electronics/Channel Master NPL Site (the site) located at 620 West
Industry Drive, Oxford, Granville County, North Carolina. This report was prepared to meet the semiannual
reporting requirements proposed in the Final Design Report (FDR) (Geraghty & Miller, 1996). The purpose of
this report is to summarize groundwater sampling results and operation information of the groundwater
remediation system from May 2008 to October 2008. The remainder of this report is organized as follows:
Section 1.0 provides a brief history of the site and the remedial design information; Section 2.0 discusses
groundwater sampling procedures and analytical results; Section 3.0 discusses the performance of the
groundwater remediation system; Section 4.0 summarizes the contents of this report; and Section 5.0 lists the
references used in this report.
1.1 Site history
The site is located in Oxford, Granville County, North Carolina and consists of approximately 13 acres of
property containing the concrete slabs and foundations of two buildings. A site layout is included as
Figure 1-1. Television antennas were once manufactured at the site; a process that involved copper and
nickel electroplating and chrome conversion coating of antenna parts. Manufacturing processes also involved
the degreasing of parts using solvents, including tetrachloroethene (PCE) and trichloroethene (TCE) (Geraghty
& Miller, 1993 and Geraghty & Miller, 1995). Spent solvents reportedly were disposed outside of the main
building near a loading dock. The site is currently owned by CMSS, Inc. and was operated by Avnet EMG for
packaging and distributing electronic parts until February 28, 2003. The main building was demolished in early
2008 to where only the concrete slab and foundation remains. The second building, identified as the former
Bandag Warehouse, was also demolished in early 2008 and only the concrete slab and foundation remain. A
detailed operational history of the site is included in the Remedial Investigation Report and Feasibility Study
reports prepared by Bechtel Environmental, Inc. (Bechtel, 1992a and 1992b}. The FDR was prepared in July
1996 and was approved by the United States Environmental Protection Agency (US EPA) in September 1996.
The groundwater remediation system consists of four (4) deep saprolite recovery wells (up to 60 feet below
ground surface), three (3) shallow recovery wells (up to 25 feet below ground surface), and one shallow tray
air stripper for treatment of volatile organic compounds (VOCs) in contaminated groundwater. The air stripper
discharges treated effluent to the City of Oxford sanitary sewer system. The total depths of the recovery wells
PW-1, PW-2, PW-3, and PW-4 are 60-feet, 37-feet, 24-feet, and 58-feet, respectively. The shallow recovery
wells that form the PW-5 cluster, designated PW-5A, PW-5B, and PW-5C, are each 25-feet deep. The
recovery well locations are presented in Figure 1-1. Details of the remediation system construction can be
found in the Final Construction Report -Revision 1 (ARCADIS G&M of North Carolina, Inc., 2000).
The treatment system startup occurred in late August 1998 and the first weekly samples from the remediation
system were collected on September 2, 1998. The analytical results of this sampling event indicated the
presence of total cyanide in concentrations that exceeded the discharge limits to surface water. Therefore, the
system was shut down when analytical results were received, and an alternative discharge route that accepted
low concentrations of total cyanide was pursued. Based on negotiations with the City of Oxford (City}, an
effluent connection to the City sewer system was installed in March 2000. The treatment system began
operation in April 2000.
On behalf of JFD Electronics and CMSS, Inc., ENSR prepared a draft Five-Year Review report for the site and
submitted it to the USEPA in April 2005. USEPA provided comments on May 31, 2005. ENSR addressed the
comments, revised the Five-Year report, and submitted it to USEPA on June 30, 2005 (ENSR, 2005a). In
addition, ENSR submitted a Technical Memorandum (ENSR, 2005b} to USEPA to address the issues raised

in their May 31, 2005 comments on the draft Five-Year Review report. North Carolina Department of
Environment and Natural Resources (NCDENR) prepared the final five-year review report for US EPA in
September 2005 (NCDENR, 2005).
1.2 Monitoring and reporting requirements
As proposed in the FDR, groundwater monitoring reports must be prepared and submitted to the US EPA on a
semiannual basis. These reports will include a description of field activities, a summary of groundwater quality
data, and a summary of water-level data. A summary of the system operation and maintenance (O&M)
program must also be included in the report.
An environmental monitoring program is required by the FDR to verify that the remediation efforts meet the
design objectives. The groundwater monitoring wells CMMW04, CMMW05, CMMW07, CMMW10, CMMW15,
CMMW17, CMMW19, CMMW20, CMMW21, CMMW22 (replaced by well CMMW22A), CMMW23, CMMW24,
CMMW26, the Finch water supply well, the recovery wells, and the treatment system influent and effluent must
be sampled periodically in accordance with the FDR. The frequency of monitoring and parameters for
analysis, modified based on the sewer system permit issued by the City, are listed on Table 1-1. Since the
initiation of the remediation system operation, groundwater monitoring reports have been submitted on a semi-
annual basis. This report summarizes the groundwater monitoring and O&M program from May 2008 to
October 2008. •

2.0 Groundwater monitoring
As proposed in the FDR and shown on Table 1-1, groundwater samples were collected from the designated
monitoring wells at the site on a semi-annual basis. In addition, water levels in the monitoring and recovery
wells were collected. Section 2.1 briefly describes the water level measurements and Section 2.2 describes
the monitoring well sampling activities performed in October 2008. Analytical results of the semi-annual
monitoring are discussed in Section 2.3.
2.1 Water level measurement
Prior to collecting groundwater samples, the elevation of the water table was measured in monitoring wells at
the site using an electronic water level meter. Water levels measured on October 20, 2008, in the monitoring
and recovery wells as part of the semi-annual monitoring event are presented in Table 2-1. Potentiometric
surface maps of groundwater at the site were prepared based on depth to groundwater measured during the
sampling event. Figure 2-1 presents the groundwater potentiometric map for shallow and intermediate wells
under pumping conditions at the site. Based on this map, the general direction of groundwater flow is primarily
to the east. As shown on Figure 2-1, groundwater drawdowns were observed in the vicinity of recovery wells
PW-1, PW-2, PW-3, and PW-4 due to groundwater pumping. Water levels throughout the site are generally a
few feet lower than in April 2008 but appear to have rebounded from the drought experienced in the area in
2007.
2,2 Groundwater sampling
The results of groundwater sampling for October 2008 are described in the remainder of this section. The
frequency of the monitoring program is summarized in Table 1-1 . The monitoring events were· performed in
general accordance with the procedures described in the Performance Standard Verification Plan (PSVP),
which was included as Appendix E to the Revised Operation and Maintenance Plan -Groundwater
Remediation (ENSR, 2002). The sampling and analytical procedures are summarized below.
Water levels were measured in the monitoring wells located at the site prior to groundwater sampling. Prior to
sampling, each monitoring well was purged with either a submersible or peristaltic pump while monitoring for
dissolved oxygen (DO), oxidation-reduction potential (ORP), pH, temperature, and specific conductivity for
approximately three well volumes. Field equipment used for sampling was decontaminated according to the
PSVP after use at each well. Decontamination water and purge water was collected in a polyethylene tank for
treatment and disposal through the on-site air stripper system.
As part of the quality control, trip blanks, equipment blanks and field blanks were collected and analyzed for
voes. In addition, one duplicate sample was collected and analyzed for voes. All samples were
immediately preserved and placed in an ice chest after collection. The groundwater samples were shipped to
Test America Laboratories, Inc. (formerly Severn Trent Laboratories) located in Savannah, Georgia, for
analysis.
The October 2008 sampling event was performed on October 20 and 21, 2008. As part of the routine semi-
annual sampling event, a total of 13 monitoring wells (eMMW04, eMMW05, eMMW07, eMMW10, eMMW15,
CMMW17, eMMW19, eMMW20, eMMW21, eMMW22A, CMMW23, eMMW24, and eMMW26) as well as
and pilot-study wells IW-1 and POW-1 were sampled and analyzed for volatile organic compounds (VOes) by
USEPA Method 8260. The sample collected from monitoring well eMMW04 was also analyzed for total and
amendable cyanide by USEPA Method 9010. Figure 1-2 presents the locations of these wells. The data were
validated by ENSR using Level II Data Quality objectives. The field parameters and analytical results are
respectively summarized in Table 2-2 and Table 2-3.

Groundwater samples from the treatment system infiuent and effiuent were also collected on October 15,
2008. These samples were analyzed for VOCs and total cyanide. The analy1ical results for the system infiuent
and effluent are discussed in Section 3.2.
2.3 Results and discussion
Table 2-2 and Table 2-3, respectively, summarize the field parameters and laboratory analy1ical results for
groundwater samples collected in October 2008. Historical analy1ical results for monitoring wells in the routine
monitoring program are summarized in graphs in Appendix A. The laboratory report for the October 2008
sampling event is included in Appendix B. Figure 2-2 presents the trichloroethylene (TCE) and
tetrachloroethylene (PCE) concentrations in groundwater samples collected in October 2008. The following
sections briefiy discuss the sampling results for October 2008.
2.3.1 VOCs in on-site monitoring wells
The on-site wells in the routine monitoring program include monitoring wells CMMW04, CMMW05, CMMW10
and CMMW15.
The concentrations of PCE, TCE, cis-1,2-dichloroethene (cis-1,2-DCE) in monitoring well CMMW04 continued
to fiuctuate. PCE and TCE concentrations decreased from the April 2008 concentrations of 480 micrograms
per liter (µg/L) and 4,500 µg/L, respectively, to 450 µg/L and 4,100 µg/L, respectively. Cis-1,2-DCE
concentration in October 2008 was 150 µg/L, above the remediation goal of 70 µg/L. During the October 2008
sampling event, a duplicate sample was obtained from monitoring well CMMW04. Total and amenable
cyanide concentrations in this well have been relatively stable and below the remediation goal of 154 µg/L
since October 2002.
The measured PCE and TCE concentrations in well CMMW05 during the October 2008 sampling event were
12,000 µg/L and 68,000 µg/L, respectively. PCE and TCE concentrations increased in April 1999, after the
initial system startup in August 1998. PCE concentrations have been fiuctuating slightly, but the concentration
trend has been declining since October 2005 (refer to Appendix A for graphs). TCE concentration increased
slightly again in October 2008, but the overall trend is downwards since April 2002. Cis-1,2-DCE
concentration was measured at 990 µg/L in October 2008. Vinyl chloride concentration in well CMMW05 was
below the reporting limit (RL) of 500 µg/L. Presence of cis-1,2-DCE is indicative of reductive dechlorination in
this well.
In October 2008, PCE and TCE concentrations in monitoring well CMMW10 decreased to 120 µg/L and
1,200 µg/L, respectively. PCE and TCE concentrations were 630 µg/L and 4,100 µg/L, respectively, in April
2008. PCE and TCE concentrations have remained at significantly lower concentrations than those found prior
to the enhanced reductive dechlorination (ERO) pilot test (PCE concentration of 7,100 µg/L and TCE
concentration of 160,000 µg/L, respectively, sampled on October 6, 1999). The concentration of cis-1,2-DCE
decreased from 350 µg/L in April 2008 to 250 µg/L in October 2008. Vinyl chloride concentrations increased
from below the RL of 20 µg/L in April 2008 to 170 µg/L in October 2008. The low PCE and TCE
concentrations relative to pre-ERO pilot testing and decreasing concentrations of degradation products
indicate that reductive dechlorination is continuing to occur in this well. To assess whether organic carbon is
present to support continued reductive dechlorination, the groundwater sample from this well was analyzed for
TOC. The result indicated that TOC was 1.4 milligrams per liter (mg/L), which is very low and similar to that
found before the ERO pilot test.
To further assess if ERO has continued to occur in the former ERO pilot test area, groundwater samples were
collected from wells IW-1 and POW-1 (ERO pilot test injection and monitoring wells). The results indicate that
the parent compounds, PCE and TCE were below Rls while vinyl chloride, a degradation product of

PCEfTCE, was detected at 130 ug/L and 63 ug/L, respectively, in these wells. TOG was measured at 51 mg/L
and 35 mg/L, respectively in wells IW-1 and POW-1, and these levels are sufficient to continue to support
reductive dechlorination.
The PCE and TCE concentrations in monitoring well CMMW15 were relatively low (1.4 µg/L and 89 µg/L,
respectively). PCE and TCE concentrations decreased from those measured in April 2008 (2.5 µg/L and 160
µg/L). PCE and TCE constituents have been fluctuating since significant reduction in 2002 and 2003.
2.3.2 voes in off-site wells
The key offsite wells routinely monitored include monitoring wells CMMW07, CMMW17, CMMW19, CMMW20,
CMMW21, CMMW22a, CMMW23, CMMW24 and CMMW26. Table 2-3 presents the October 2008 results.
The following sections briefly discuss the VOC trends in these wells.
The PCE and TCE concentrations in monitoring well CMMW07 are relatively stable compared to April 2008.
The PCE concentration decreased from 21 to 17 µg/L and the TCE concentration increased from 220 to
230 µg/L. The concentration of cis-1,2-DCE decreased from 38 to 30 µg/L (see Appendix A). The overall
trend since 2001 has been downwards for these constituents in this well.
The PCE, TCE, and vinyl.chloride concentrations in the off-site monitoring well CMMW17 (deep bedrock well)
were below the laboratory RL of 1.0 µg/L, similar to April. The cis-1,2-DCE concentration decreased slightly
from 130 µg/L in April 2008 to 99 µg/L in October 2008. The overall trend for PCE and TCE is downwards,
while that for cis-1,2-DCE is slightly upward which indicates likely attenuation of parent compounds.
. PCE and TCE concentrations in well CMMW19 have been fluctuating slightly after a strong decline in 2000.
PCE and TCE concentrations decreased slightly compared to April 2008. PCE, TCE and cis-1,2-DCE
concentrations measured in April 2008 were 16 µg/L, 22 µg/L and 90 µg/L, respectively. PCE, TCE and cis-
1,2-DCE concentrations measured in October 2008 were 10 µg/L, 18 µg/L and 68 µg/L, respectively. Vinyl
chloride was detected at 2.2 µg/L in October 2008. Chlorobenzene was also detected at 54 µg/L in this well.
The VOC concentrations in monitoring well CMMW20 decreased slightly compared to the April 2008 levels,
with an overall downward historical trend of both PCE and TCE. PCE, TCE, and cis-1,2-DCE concentrations
measured in April 2008 were 470 µg/L, 26 µg/L, and 14 µg/L, respectively. PCE, TCE, and cis-1,2-
concentrations measured in October 2008 were 330 µg/L, 19 µg/L, and 12 µg/L, respectively. Vinyl chloride
concentration was below RL of 5.0 µg/L. 1, 1-DCE was also present in well CMMW20 in October 2008 at
6.7 µg/L.
In monitoring well CMMW21, the PCE and cis-1,2-DCE concentrations continue to increase (1,100 µg/L and
320 µg/L, respectively) since October 2006. TCE decreased slightly from 140 µg/L in April 2008 to 120 µg/L in
October 2008. Vinyl chloride concentration was below RL of 5.0 µg/L in October 2008. Although no longer
term trends are evident from the data gathered so far (see Appendix A), the historical presence of vinyl
chloride and cis-1,2-DCE as well as low ORP and DO concentrations indicate that reductive dechlorination is
a potentially important attenuation mechanism at this well.
All VOCs in well CMMW-22A were below the RL of 1.0 µg/L in October 2008. Historically, this well has
contained low levels of VOCs since it was installed in 2000.
Concentrations of PCE, TCE and cis-1,2-DCE in monitoring well CMMW23 increased since April 2008. PCE,
TCE, and cis-1,2-DCE concentrations measured in October 2008 were 320 µg/L, 71 µg/L, and 150 µg/L. PCE,
TCE, and cis-1,2-DCE concentrations measured in April 2008 were 200 µg/L, 41 µg/L, and 80 µg/L,
respectively and were consistent with concentrations observed in this well prior to the large decrease in April
2007. The October 2008 TCE and cis-1,2-DCE concentrations are the highest measured concentrations in
CMMW23 since monitoring began, and the PCE concentration is the highest it has been since 2001.

However, all VOC concentrations are well within an order of magnitude of the lowest detected concentrations
over the monitoring history. Therefore, as proposed in our response to EPA comments dated July 31, 2008 on
the additional data collected as part of the 5-year review, no additional soil gas monitoring is warranted at this
time.
The PCE and TCE concentrations in well CMMW24 decreased slightly from 1.6 µg/L and 4.7 µg/L,
respectively, in April 2008 to 1.3 and 4.5 µg/L in October 2008. Cis-1,2-DCE and vinyl chloride remained
below Rls.
The concentrations for PCE, TCE, cis-1,2-DCE and vinyl chloride in well CMMW26 have remained below Rls
. since April 2002 with the exception of a low level PCE detection of 2.5 µg/L in April 2007.

3.0 Remediation system performance
In accordance with the FDR, the performance of the recovery system was evaluated to verify if the
performance standards were being met. The recovery system was evaluated with respect to the groundwater
drawdown and groundwater quality. The remainder of this section describes the recovery system evaluation.
3.1 Recovery system performance
Potentiometric surfaces based on water level measurements in October 2008 are presented on Figure 2-1.
The PSVP in the FDR proposed monitoring hydraulic parameters to evaluate if the predicted capture zone is
maintained during operation of the groundwater recovery system. The approach proposed in the PSVP was to
compare the predicted drawdown with actual drawdown in selected monitoring wells. A comparison of
predicted versus actual drawdown is presented in Table 3-1. Based on the data in this table, actual
drawdowns in selected wells were found to be greater than the predicted drawdowns in the FDR. Drawdown
in key extraction and monitoring wells indicates likely establishment of capture zones as predicted in the FDR.
Water levels across the site appear to have rebounded from drought conditions experienced in 2007.
3.2 Treatment system performance
The treatment system infiuent was sampled in October 2008. Table 3-2 summarizes the detected constituents
in the air stripper infiuent. Concentrations of VOCs were generally higher than April 2008 detections but lower
than October 2007 detections, with PCE, TCE, and cis-1,2-DCE at 340 µg/L, 3,100 µg/L, and 72 µg/L,
respectively in October 2008 compared to 410 µg/L, 4,300 µg/L, and 66 µg/L in October 2007 and 110 µg/L,
34 µg/L, and 31 µg/L in April 2008. Total cyanide concentration in the influent was 0.0057 mg/L, consistent
with recent detections. A summary of the analy1ical data for the effluent is included as Table 3-3. The air
stripper effluent results have been previously reported to the City of Oxford. The analy1ical results in this table
indicate that the treatment system has been consistently reducing VOCs to below their respective Rls.
Total cyanide concentration in the effluent in October 2008 was 0.0061 mg/L, below the permit limit of 0.05
mg/L.
As part of the routine monitoring, flow totalizer data were collected from recovery wells PW-1 through PW-4.
Flow from the three recovery wells, PW-5A, PW-5B, and PW-5C, are recorded by a common totalizer. These
wells, which make up the PW-5 group, are controlled by water level sensors in the wells and only run
intermittently depending upon groundwater recharge. Using the totalizer data and the sampling dates,
average fiow rates were calculated. Table 3-4 presents a summary of the recovery well fiow data and
estimated extraction system flow rates. Reported flow rates are recorded at the time of sample collection and
represent instantaneous flow rates for that particular time. The calculated (estimated) flow rates are based on
totalizer readings averaged over the time between sampling events and are less affected by short-term
variations in pump performance that may occur at any given time. Based on data in this table, slight
fiuctuations in the groundwater extraction rates were observed but do not appear to be seasonal.
3.3 Operation and maintenance
O&M was performed in general accordance with the Revised Operation and Maintenance Manual (ENSR,
2002). As part of the monitoring, pressure readings from the individual recovery system headers were
recorded monthly to monitor the performance of the recovery pumps. Pressure readings were also monitored
and recorded monthly to evaluate the performance of the air blower and to identify trends that might indicate
scale build up inside the air stripper that could impact the unit's treatment efficiency. Table 3-5 presents a
summary of the air stripper blower pressure data and calculated air fiow rates from May 2008 to October 2008.
The static pressure was steady and fluctuated between 19 to 22 inches of water column indicating no

significant scale build-up in the air stripper. The calculated air flow rates ranged between 677 and 7 47
standard cubic feet per minute.
The system experienced no recorded instances of unscheduled system-wide downtime. However, PW-5 wells
were not operational from June 3 through 7, 2008 due to a damaged fiange. The PW-5 wells were back online
and the system operated normally after the flange was replaced on June 7, 2008.

4.0 Summary
Since operation of the recovery system began, a total of 66,088,990 gallons of groundwater have been treated
at the site. The treatment system has been performing as anticipated and has been effective in treating the
voe impacted groundwater. voes in the ERO pilot test area have continued to undergo reductions likely due
to the remaining organic carbon from the pilot injection program. In addition, voes at other locations (e.g.,
near wells eMMW17, eMMW19, eMMW21, etc.) show evidence of natural attenuation.

CMMW-22 has been destroyed, probably due to site clearing activities by the site owner
Therefore, a replacement well CMMW-22A was lnstalled in July 2000.
Top of the well covers are used as measuring points for recovery wells, whereas the
measuring point elevations for monitoring wells are top of the casing.

Total pressures are collected from a port located in the sump near air inlet to the air stripper.
Velocity pressure is the difference between the total pressure and static pressure.
Air fiow rates (standard cubic feet per minute or SCFM) were calculated using formula for a Dwyer Model 200-130
air fiow meter using a single point insertion pitot tube (Dwyer Instruments Bulletin No. H-11)

Data validation was performed on one data package from Test America, Savannah for water samples. The
samples were collected October 20-21, 2008 at the Channel Master Site and were reviewed for conformance to
the requirements of SW-846, Test Methods for Evaluating Solid Waste Physical/Chemical Methods. Test
America·, Savannah processed the samples and reported the results under sample delivery group (SDG) 680-
41549. The following analytical methods were requested on the chains-of-custody (COC) and/or by the project
manager:
• Method 8260B -Volatile Organic Compounds by Gas Chromatography/ Mass Spectrometry;
• Method 415.1 -Total Organic Carbon;
• Method 335.1 -Amenable Cyanide; and
• Method 335.4 -Total Cyanide.
Data were validated using the United States Environmental Protection Agency ( USE PA) Contract Laboratory
Program National Functional Guidelines for Organic Data Review (July 2007) and USEPA Contract Laboratory
Program National Functional Guidelines for Inorganic Data Review (October 2004), modified for method-specific
requirements.

• Agreement of analyses conducted with the chain of custody (COC) requests;
• Holding times and sample preservation;
• Gas chromatography/mass spectrometry (GC/MS) tunes;
• Initial and continuing calibrations;
• Method blanks/trip blanks/equipment blanks;
• Surrogate recoveries;
• Matrix spike/matrix spike duplicate (MS/MSD) results;
• Field duplicate results;
• Laboratory control sample/laboratory control sample duplicate (LCS/LCSD) results; and
• Quantitation limits and sample results.
Samples
ENSR collected seventeen (17) water samples, one (1) equipment blank, one (1) field blank, one (1) field
duplicate, and one(1) trip blank on October 20-21, 2008.

Analytical Results
In general, the data are valid as reported and may be used for decision making purposes.
The following samples required a dilution to minimize matrix effects and/or bring the analyte concentrations into
the calibration range. The dilutions caused the sample detection limits to be elevated.
Sample ID Method Sample ID Method
Sys-Inf 8260B CMMW-04 8260B
CMMW-07 8260B CMMW-10 8260B
.CMMW-21 8260B CMMW-05 8260B
It was noted that Test America, Savannah needed to reanalyze several of the samples with a dilution in order to
meet instrument calibration limits. Test America, Savannah reported both diluted and undiluted results. As a
result, some data points were qualified as estimated "E" by the laboratory. The ENSR validator rejected these
results because they were over the calibration range. The diluted sample results were qualified as diluted "D" by
the laboratory. These qualifiers were removed by the ENSR data validator. See Table 1.
DISCUSSION
Agreement of Analyses Conducted with COC Requests
Sample reports were checked to verify that the results corresponded to analytical requests as designated on the
COC and subsequent communications with ENSR.

Sample coolers were all received within the 4±2 °C requirement for all analyses.
All samples were chemically preserved to the proper pH.
Tunes and Calibrations
Gas chromatography-mass spectrometry hardware tune summaries were not submitted for validation in this Level
II data package. Initial and continuing calibration data were not submitted for validation.
Blanks
No target analytes were detected at concentrations exceeding the reporting limits in the laboratory blanks for the
analyses requested on the COC.
Surrogates
All surrogates were within the quality control limits.
MS/MSD Recoveries
All MS/MSD recoveries were within the advisory limits.
Field Duplicate Results
A field duplicate sample was collected on sample CMMW-04. See Table 2 for the Relative Percent Difference
(RPD) for the compounds with detections. The RPDs between the original and field duplicate results were less
than the maximum advisory limit of 30%, or the difference between the original and field duplicate results was less
than the reporting limit for results less than five times the reporting limit with the exception of Ammenable
Cyanide. See Table 1 for qualifiers.
LCS/LCSD Results
All LCS/LCSD recoveries were within the QC acceptance limits.
