RE: Third Quarter 2003 Groundwater Monitoring Report for the
Former Koppers Company Site, Morrisville, North Carolina
RETEC Project No.: BEAZ7-03624-103
Dear Ms. Hudson:

The RETEC Group, Inc. (RETEC), on behalf of Beazer East, Inc. (Beazer), hereby submits the results ·of
the third quarter 2003 groundwater monitoring event at the former Koppers Company Site in Morrisville,
North Carolina (Site). This report documents the field and laboratory results of the groundwater
monitoring event performed on August 25, 2003.
Groundwater Monitoring Program-Third Quarter 2003
Based on the requirements in the Proposed Remedial Action Groundwater Monitoring Program
(ThermoRetec, 1999),1 the third quarter 2003 groundwater monitoring event included the following:
• Gauging of 50 monitoring wells (Figure I): 35 on-site wells and 15 off-site wells
• Sampling of two on-site wells: C-29B and PW-01
Although wells C-14A and M-04 were scheduled to be sampled in this event, RETEC field personnel
determined that the volume of water present in these wells was not sufficient to generate a sample.
Groundwater Elevation and Direction of Flow
Groundwater elevations for the A-, B-, and C-zone wells, as measured on August 25, 2003, are presented
in Table I. The groundwater elevations presented in Table I were used to construct the A-, B-, and C-
zone groundwater potentiometric surface maps shown in Figures 2 through 4.
Historic groundwater elevations for wells C-0 LB and C-lOB differ significantly from the historic
groundwater elevations in the other B-zone wells. These consistently different groundwater elevations, in
conjunction with the fact that these wells are 30 to 55 feet deeper than the neighboring B-zone wells,
indicate that wells C-0IB and C-IOB do not communicate with the rest of the B-zone aquifer. Because of
this lack of communication, wells C-0IB and C-l0B will continue to be gauged, but will not be included
in the data set used to construct the potentiometric surface map for the B-zone (Figure 3).
Figures 2 and 3 show the cone of depression that exists around the pumping well (PW-0 I) and indicate
that, outside of the zone of influence, groundwater flow is generally to the northeast and south-southwest.

The high variability in the C-zone groundwater elevations indicate that these wells are screened m
isolated fracture zones within the bedrock, as seen on Figure 4.
Phenolic Analytical Results
Each groundwater sample was analyzed for 2,4-dichlorophenol and pentachlorophenol using the United
States Environmental Protection Agency (USEPA) Method 8270C-Select Ion Monitoring. RETEC
personnel validated the groundwater analytical results and applied the necessary data qualifiers, as
summarized in Table 2. A complete copy of the laboratory analytical results and data evaluation report is
provided in Appendix A.
The Record of Decision for this Site requires that groundwater meet the following cleanup standards:
• 20 micrograms per liter (µg/L) for 2,4-dichlorophenol
• I µg/L for pentachlorophenol
As shown in Table 2, pentachlorophenol was detected in groundwater sampled from wells C-29B and
PW-0 I. Both of these pentachlorophenol detections exceeded the pentachlorophenol cleanup standard of
l µg/L. However, 2,4-dichlorophenol was not detected in any of the samples analyzed during this event.
In accordance with the USEPA-approved Groundwater Monitoring Program, RETEC will continue to
collect quarterly samples from all wells with pentachlorophenol and/or 2,4-dichlorophenol results above
the specified cleanup standards. This sampling will continue until the concentrations of
pentachlorophenol and 2,4-dichlorophenol meet the cleanup standards for four consecutive sampling
events.
Since pentachlorophenol was detected in groundwater sampled from wells C-29B and PW-0 I above the
cleanup standard, these wells will be sampled as part of the fourth quarter 2003 groundwater monitoring
event.
Wells C-14A and M-04 were scheduled to be sampled in the third quarter 2003 event, but both wells had
an insufficient quantity of water to sample. Therefore, in the fourth quarter 2003 groundwater monitoring
event. RETEC will attempt to sample wells C-14A and M-04. Well C-14A is on the quarterly
sampling schedule and M-04 is on the annual sampling schedule.
Dioxin and Furan Analytical Results
Dioxin and furan sampling by USEPA Method 8290 occurs on a semiannual basis in a subset of
wells. The Groundwater Monitoring Program requires that dioxin and furan samples be collected
semiannually from wells that had concentrations of pentachlorophenol at or above the specified
cleanup levels during the previous sampling event, or wells with two or more quarterly
pentachlorophenol detections in the previous four quarters. Therefore, in agreement with the
USEPA-approved Groundwater Monitoring Program, the next dioxin and furan sampling event will
occur in the fourth quarter of 2003 when wells C-l4A, C-29B, and PW-01 will be sampled for
dioxins and furans.

Operational Summary
The groundwater extraction system is currently pumping at its optimum. The aquifer's low yield will not
support a pumping rate greater than 2 gallons per minute, nor will the low yield of the aquifer support the
"pulsing" of the system.
Quarterly review of the groundwater analytical results indicate that the concentrations of constituents of
interest are fluctuating in groundwater collected from the three remaining wells with groundwater impact
(Cl4A, C-29B, and PW-01). Monitoring will continue in order to determine the rate at which the levels
of impact are fluctuating.
If you have any questions regarding these results, please call Michael Helbling of Beazer at (412) 208-
8858 or Rita Bauer at [phone].
Sincerely,
The RETEC Group, Inc.

Laboratory: Severn Trent Laboratories, Inc. -Pittsburgh
Laboratory Project Number: C3H260301
Analyses: Pentachlorophenol and 2,4-Dichlorophenol by SW-
846 Method 8270 SIM
Evaluator: Gregory A. Malzone
Date: September 5, 2003
The Raleigh Q3-03 data report from Severn Trent Laboratories, Inc. -Pittsburgh was
evaluated using USEP A National Functional Guidelines and USEP A method
specifications. Each issue requiring comment and/or data qualification is addressed
below.
II
Sample Collection, Receipt, and Log-In
Sample Collection: Wells C-14A and M-04 were dry. Samples could not be
collected for these wells.
Sample Receipt: Samples were received by the laboratory in good condition and
within the optimal temperature range of 2-6° C.
Pentachlorophenol and 2,4-Dichlorophenol by SW-846 Method 8270
SIM
Dilutions/Reporting Limits: Samples PW-01, PW-0 l_DUP, and C-29B required
analyses at four-fold dilutions to bring the pentachlorophenol concentrations into
the calibration range. The dilutions caused the reporting limits of 2,4-
dichlorophenol to be elevated.
Matrix Spike Recoveries and RPDs: The PW-01 MS recovery for
pentachlorophenol exceeded the upper advisory limit. In addition the relative
Beazer/Raleigh
QJ-03 Client Work Product
Private and Conji.Jentia/
percent difference (RPD) between the matrix spike recoveries exceeded the
maximum limit. The positive pentachlorophenol results for PW-01 and! PW-
Ol_DUP were qualified as estimated, "J," because of the high bias and
imprecision caused by matrix effects.
Ill Field Duplicate Samples
Samples PW-01 and PW-01_ DUP were the primary and field duplicate samples
collected for this sampling event. No data qualifications are required based on the
RPD of field duplicate sample data. However, the positive results are preseILted in
the table below to evaluate precision and sample homogeneity. An RPD greater
than the advisory limit of 30% is an indication of sample heterogeneity with
respect to that compound, poor field precision and/or poor laboratory precision.
Field and laboratory precision were acceptable.
