Project No. BEAZ?-03624-103 Dear Ms. Hudson: The results of the third quarter 2000 groundwater monitoring event for the former Koppers Company, Inc. site in Morrisville, North Carolina are submitted by RETEC North Carolina, Inc. on behalf of Beazer East, inc. This report documents the field and laboratory results of the groundwater monitoring event that was performed September 27, 2000. Enclosed is a copy of the third quarter 2000 analytical results (Enclosure I). The third quarter 2000 monitoring event included gauging the water levels in 47 wells and sampling and analyzing six of these wells (C-IOB, C-14A, C-14B, C-29B, M-04 and PW-01) shown in Figure I (Enclosure 2). All groundwater samples were analyzed for pentachlorophenol and 2,4-dichlorophenol by Method 8270C -Select Ion Monitoring. Samples from wells C-14B, C-29B and PW-I were analyzed for dioxins and furans by Method 8290. Groundwater elevations for the A-, B-, and C-Zone wells measured on September 27, 2000 arc presented in Table I (Enclosure 3). These elevations were used to construct the groundwater contour maps shown in Figures 2, 3, and 4 (Enclosure 2). Groundwater flow for the site is generally to the northeast and south-southwest from a ridge that roughly bisects the site. The analytical results of groundwater samples from six wells arc summarized in Table 2 (Enclosure 3) and are reported with any necessary data validation qualifiers: Pentachlorophenol was detected in groundwater samples from C-14A, Cl4B, C-29B, M-04, and PW-01. The detection limit for the sample from well M-04 was elevated because the low yield of water from the well limited the sample volume giving a result of I. I U µg/L for this sample. A review of the laboratory data showed that pentachlorophenol was detected below the analytical detection limit at a concentration of 0.88 J µg/L where the J qualifier indicates that this result is estimated. Dioxins and furans were detected in groundwater samples from wells C-14A, C-29B, and PW-I as shown on Table 2. Table 3 shows the concentrations of dioxins and furans detected rcponcd I I I I I I I I I I I I I I I I I I I Ms. Beverly Hudson December 18, 2000 Revised April 11, 2001 Page 2 .ThermoRetec with their calculated Toxicity Equivalent Quotient (TEQ) concentration. The TEQ concentration is calculated by multiplying the concentration of each dioxin or furan by its respectiYe Toxicity Equivalent Factor (TEP). The resulting TEQ concentrations arc then summed to dctc1minc the total TEQ. The Record of Decision (ROD) for this site requires that groundwater meet the cleanup standards of 1 µ.g/L for pentachlorophenol, of 20 µ.g/L for 2,4-dichlorophenol, and of 30 pg/L for dioxins and furans. Table 3 (Enclosure 3) shows analytical results from the third quarter 2000 sampling event that exceeds these cleanup standards. The cleanup standard for pentachlorophenol is exceeded in samples from wells C-14A, Cl4B, C-29B, and PW-01 but not in well M-04. The sample from well C-14A also exceeds the cleanup standard for dioxins and furans. In accordance with the USEPA-approved Groundwater Monitoring Program, quarterly sampling of all wells with reported results above the specified cleanup levels will continue until four consecutive sampling events indicate that the concentrations of pentachlorophenol and 2,--1- dichlorophenol meet the cleanup levels. Since pentachlorophenol has continued to be detected in groundwater samples from wells C-14A, Cl4B, C-29B, and PW-01, these wells will be sampled during the fourth quarter monitoring event. Well M-04 will be placed on an annual monitoring schedule. Dioxins and furans will be analyzed semi-annually in wells in which pentachlorophenol is detected, so these constituents will not be analyzed again until the first quarter 2001 monitoring event. If you have any questions regarding these results, please call Michael Helbling of Beazer at (41:) 208-8867 or Laura Kelmar at (978) 371-1422. Sincerely, RETEC North Carolina, Inc.

Malzone Date: November 20, 2000 The Raleigh, Morrisville Q3-00 data reports from Severn Trent Laboratory-Pittsburgh and Alta Analytical Laboratory were evaluated using USEPA Nntio,wl Fu11ctio11n/ Guideli11es and method specifications. Each issue requiring comment and/or data qualification is addressed below. Qualified results are listed in balded text. Pentachlorophenol and 2,4-Dichlorophenol by SW 8270C SIM I. 2. Surrogate Recoveries: A 20-fold dilution was required for sample C-29B to bring the Pcntachlorophenol concentration into the calibration range of the GC/MS instrument system. This dilution was sufficiently high to dilute out the surrogates. Method accuracy and extraction efficiency cannot be assessed for this sample. However, there were sufficient acceptable quality control check results to show that the analytical process was in control. No data qualifications were necessary based on professional judgement. Matrix Spike Recoveries: Sample C-1 OB was designated in the field to be processed as the quality control check sample for this round. The C-1 OB MS/MSD recoveries for Pentachlorophenol were 176% and 171 %. Both were greater than upper adviso.ry limit of 140%. USEPJ\ Natio11ai Fu11ctio1wl Guiddi11es do not require global data qualification based on organic matrix spike data alone. However, a high bias attributabk to matrix effects is indicated for sample C-1 OB. The l'cntachlorophenol result for C-1 OB was a non-detect. Nu data qualifications are necessary.
