Correlation of Copper and Lead Field Screening Data vs. Fixed Lab Data Appendix F-1 Field Screening - CLP Data Correlation
EPA directed Brown and Root Environmental to determine the correlation between data analyzed by field screening and CLP methodologies at the Raymark - Ferry Creek site. A strong correlation would allow for the use of field screening data in quantifying risk at the site. Two statistical procedures were used to determine the correlation between data analyzed by field screening and CLP methodologies: linear regression, which evaluates the correlation on a point-by-point basis; and a nonparametric t-test, which compares the means of two data sets for each method. Paired data selected for the correlation determination were collected at the same location and same depth.
For the first statistical analysis, a scatter plot of paired data was generated for each chemical with the field screening results plotted along the x-axis and the CLP results plotted along the y-axis. A linear regression was then performed on the scatter plot and a correlation coefficient was generated. For data that are strongly correlated, the scatter plot will exhibit a linear relationship with a correlation coefficient (r) of slightly less than 1. The copper and lead data had relatively high correlation coefficients of 0.87 and 0.86, respectively. The PCB data had extremely low correlation coefficients. The PCB scatter plots show that some correlation exists at low concentrations (< 1 ppm), but that this correlation weakens as concentrations increase. This may be due to the narrower calibration ranges of the field screening techniques.
For the second statistical analysis, the field screening data was grouped into one population and the CLP data was grouped into a second population. The Wilcoxon Rank-Sum (WRS) test, a distribution-free or nonparametric t-test, was performed on the two populations to determine whether their means were statistically equivalent. The copper and lead data had statistically equivalent means; the PCB data did not.
Based on the results of the two statistical analyses, the use of field screening data to quantify risk at the site is acceptable for copper and lead, but not for PCBs f"

Connecticut 06106-5127 Reference: CLEAN Contract No. N62472-90-D-1298 Contract Task Order No. 0260 Subject: Calculated CTDEP Remediation Standards Lower Subase Remedial Investigation Naval Submarine Base - New London, Groton, Connecticut Dear Mr. Lewis: :n preparation of the Lower Subase Remedial Investigation (Rl) Report. Brown & Root Environmental has calculated Remediation Standards following the State of Connecticut Remediation Standard Regulations of January 1996. Stanaaras were developed for ail cnemicals that were analyzed for during the Rl sampling and analysis program that did not have previously established CTDEP standards. The intent of this memo is to identify the sources of the standards to be used in the Rl Report and to identify those values which have been developed by B&R Environmental using the State guidance. Background information and the calculated Remediation Stanaaras are provided in Table " and Table 2. respectively, which are enclosed. Table 1 summanzes the basis for the chemicai specific remediation standards (i.e., promulgated, calculated, or calculated using a surrogated to be included in the Rl. The calculatea soil Direct Exposure and Pollutant Mobility standards. as well as the Grounawater Stanaard. are provided in Table 2. ;t should be noted that pollutant mobility and groundwater stanaards for GA classified grounawater are proviaed in Table 2 for completeness. The groundwater at the Lower Subase is classifies as G3. therefore standaras applicable to GB classified grounawater will be empnasizea in the Lower Subase Rl Report. Mr. Mark Lewis Connecticut Department of Environmental Protection December 23, 1997 - Page 2 B&R Environmental intends on using these critena. as well as Region III RBCs. as part of the human health risk assessment for the Lower Subase Rl to screen for chemicals of potential concern. Therefore. B&R Environmental, on the behalf of the United States Navy, requests that the CTDEP review and approve the standards in Table 2. It is hoped that pnor approval of the criteria will alleviate unnecessary revisions to the Rl Report in the future and expeaite any additional nsk-related work required by the State (i.e., application for use of alternative critena). Due to the current time constraints for prepanng the Lower Subase Rl, it is requested that the CTDEP complete their review by no later than January 16, 1997. If you have any questions regarding the information provided in the tables or the schedule for the review please contact Mr. Mark Evans at (610) 595-0567 (ext. 162) or me at (412) 921-8244.

Responses to CTDEP's comments have been prepared and the appropnate revisions have been made to Tables 1 and 2, which were previously enclosed in B&R Environmental^ Decemoer 23. 1997 letter. B&R Environmental, on the behalf of the United States Navy, Northern Division Facilities Engmeenng Command and Naval Submarine Base - New London, has enclosed the Navys responses to CTDEP's comments and the revised tables for your review and approval. If you have any questions regarding the responses or the information provided in the revised tables, please contact Mr. Mark Evans at (610) 595-0567 (ext. 162) or me at (412) 921-8244 It is anticipated that any remaining issues can be resolved during a conference call. Very truly yours. // Project Manager Enclosure(s) c: Mr. Roger Boucher, NORTHDIV (letter only) Mr. Mark Evans, NORTHDIV Mr. Andy Stackpole, NSB-NLON Environmental Mr. John Trepanowski, B&R Environmental Mr. Daryl Hutson, B&R Environmental (letter only) Ms. Karen Smecker, B&R Environmental File: CTO 0260 RESPONSES TO CTDEP'S COMMENTS (2/27/98) ON THE CALCULATED CTDEP REMEDIATION STANDARDS (12/23/97) CTO 260 - LOWER SUBASE REMEDIAL INVESTIGATION NAVAL SUBMARINE BASE-NEW LONDON, GROTON, CONNECTICUT MARCH 20, 1998 I. SURROGATE CHEMICALS USED TO SUPPLY TOXICITY VALUES Comment; 1. Th e Navy has used naphthalene as a surrogate to represent the toxicity of benzo(g,h,l)perylene. As noted in Dr. Ginsberg's memorandum, pyrene (RfD 0.03 mg/kg/d) is a more appropriate surrogate. The RfD for naphthalene has been withdrawn from IRIS. Please recalculate the direct exposure, pollutant mobility, and ground water protection criteria for benzo(g,h,i)perylene using this approach. This approach is appropriate for a screening level risk assessment. However, the uncertainties involved with this approach should be acknowledged if these two chemicals are found to be major risk drivers at the site. Response: The direct exposure, pollutant mobility, and groundwater protection criteria for benzo(g,h,i)perylene will be recalculated using pyrene as a surrogate. Benzo(g,h,i)perylene was detected in soil and groundwater at the Lower Subase but was not found to be a major risk driver at any of the zones that were evaluated in the risk assessment. Benzo(g,h,i)perylene was only identified as a COC in groundwater at Zone 4 where it was detected in one sample at a concentration exceeding the State's Ambient Water Quality Criteria (AWQC) for the protection of human health. Consequently, this does not have any impact on the human health nsk assessment. Comment: 2. It is unclear why the Navy calculated criteria for phenanthrene since the regulations list direct exposure, pollutant mobility, and groundwater protection criteria for this compound. Please use the criteria listed in the Regulations for this compound. The Navy should either withdraw their request for approval of criteria for phenanthrene, or, if the Navy is requesting approval of alternative criteria for this compound under the Regulations, the Navy should so state. Response The Navy retracts its request for approval of cntena for phenanthrene. The promulgated criteria for phenanthrene were used m the selection of COCs in the human health risk assessment Consequently, this does not have any impact on the human health risk assessment. 1 of 4 Comment; 3. Bromodichloromethane should be used as a surrogate for bromochlorom*"hane Please use the criteria calculated for bromodichloromethane in place of those • -ul using chloromethane as a surrogate. Response: Bromodichloromethane will be used as a surrogate for mochloromethane. Bromodichloromethane was not detected in soil and groundwater samples. ;r any of the zones evaluated in the human health risk assessment, consequently this does not have any impact on the analysis. Comment: 4. The Navy's proposal to use 3-methylphenol as a surrogate for 4-chloro-3-methylphenol is not appropriate, due to structural differences between the two compounds. The use of a qualitative risk assessment would be acceptable assuming that concentrations of this chemical do not exceed the low part-per-billion range. Please see Dr. Ginsberg's comments for additional details. Response: No criteria will be developed for 4-chloro-3-methylphenol. Instead, as suggested, 4-chloro-3 methylphenol will be evaluated qualitatively. 4-Chloro-3-methylphenol was only detected in one soil sample at the Lower Subase and at a low concentration (34 ppb), consequently, this does not have any impact on the human health risk assessment. II. INCORRECT OR UNSUPPORTED POTENCY VALUES Comment: 5. Several of the CSFs or RfDs used by the Navy appeared to be incorrect, based on a comparison to the values listed in the EPA Region III Risk Based Concentrations table, IRIS, or HEAST. Please recalculate the direct exposure, pollutant mobility, and ground water protection criteria using correct values for total 1,2-dichloroethene. Please assume that this value pertains to the mixture of c/s and trans isomers. The RfD for the mixture should be 9E-3 mg/kg/d. Response: The direct exposure, pollutant mobility, and groundwater protection criteria for total 1.2 dichloroethene will be recalculated using an oral reference dose of 9E-3 mg/kg/day. This revision does not impact the human health risk assessment since all detected concentrations of total 1.2-dichloroethene are less than the recalculated criteria. 2 of 4 Comment: 6. The Department was unable to verify the potency factors listed by the Navy for several chemicals. Please either provide references to support the listed potency factors, or derive criteria using acceptable surrogates for the following compounds: chloroethane, 4,6-dinrtro-2-methylphenol, 2-hexanone, and 2-methylnaphthalene. Please note that naphthalene is not an appropriate surrogate for 2-methylnaphthalene as the RfD for naphthalene has been withdrawn from IRIS. Please refer to Dr. Ginsberg's memo for additional guidance. Response: The toxictty criteria for chloroethane, 4,6-dinitro-2-methylphenoi, 2-hexanone,. and 2 methylnaphthalene were obtained from the current U.S. EPA Region III Risk-based Concentration (RBC) Table dated October 22, 1997. The RBC table crtes EPA's National Center for Environmental Assessment (NCEA) as the source for the values for chloroethane, 4,6-dinitro 2-methylphenol, and 2-methylnaphthalene. Although not cited in the RBC table, EPA Region III stated in telephone call on March 12, 1998, that NCEA is also the source for the toxicity crrtena for 2-hexanone. Therefore, there are no changes necessary to the proposed values. Comment: 7. The Department was unable to verify the RfD listed by the Navy for 4-nitrophenol (8.00E-3 mg/kg/d). Please either provide a reference for the listed value, or use the default RfD currently listed in the RBC tables (6.2E-2 mg/kg/d). Response: The current RBC table lists 8.00E-3 mg/kg/day as the oral RfD for 4-nitrophenol and cites EPA's NCEA as the source for the value. The value of 6.2E-2 mg/kg/day was listed in the previous, outdated version of the RBC table. Therefore, there are no changes necessary to the proposed cntena. III. POLLUTANT MOBILITY CRITERIA FOR METALS Comment: 8. The ground water protection criterion for cobalt was calculated correctly by the Navy. However, the approach used by the Navy in calculating pollutant mobility criteria for cobalt is unacceptable. Rather than using the calculated ground water protection criterion (420 ^g/l) to establish a pollutant mobility criterion for cobalt, the Navy used the EPA Region III Risk Based Criteria for tap water (2,200 ^g/L) as the GAA/GA pollutant mobility criterion. This approach is less conservative than using the calculated ground water protection criterion. The correct pollutant mobility criteria for cobalt, based on the groundwater protection criteria calculated by the Navy, are 420 ng/L for a GAA/GA area, and 4,200 ng/L for a GB area (measurement by TCLP or SPLP). 3 Of 4 Response: The pollutant mobility criteria for cobatt will be changed to 420 ^g/L for a GAA/GA area and 4,200 (AQ/L for a GB area. This revision has no impact on the human health risk assessment because of the following reasons: (1) none of the histoncal soil samples that were analyzed by TCLP had leachates that were analyzed for cobalt, and (2) only the soil samples from Zone 6 had SPLP leachates that were analyzed for cobalt and all of the results were nondetects. Comment: 9. Th eground water protection criterion for manganese was calculated correctly by the Navy. Rather than using the calculated ground water protection criterion (160 u.g/1) to establish a pollutant mobility criterion for manganese, the Navy used the EPA Secondary MCL for drinking water (50 ^g/L) as the GAA/GA pollutant mobility criterion. This approach is acceptable as it is more conservative than using the calculated ground water protection criterion. Response: No response required. IV. GB POLLUTANT MOBILITY CRITERIA FOR DIMETHYLPHTHALATE Comment: 10. The GB pollutant mobility criteria listed for dimethylphthalate (1,400 mg/kg) in the Navy's Table 2 appears to be a typo. The correct value should be listed as 14,000 mg/kg. Response: The GB pollutant mobility criteria for dimethylphthalate will be corrected to 14,000 mg/kg. "his revision has no impact on the analysis since dimethylphthalate was not detected in soil samples in any of the zones that were evaluated in the human health risk assessment. V. BIS(2-CHLOROETHOXY)METHANE Comment: 11. Th eNavy proposes a qualitative risk assessment for this compound. This approach is acceptable provided that the compound is not present at concentrations above the low part-per-billion range. As noted by Dr. Ginsberg, if it is present above this range, a more quantitative risk assessment may be required. Response: Bis(2-chloroethoxy)methane was not detected in soil or groundwater samples for any of the zones evaluated in the human health risk assessment, consequently this does not have any impact on the analysis. 4 of 4 Appendix F.3 Background Concentrations in 10 o , o, S i 1 OOOOOCDOOC5 o e> o OOOC5OC3 O C9 O Q I 8! a _ Q _ Q O" 88 o o oo o o oooo o o o o o ~ D D Q O O II o o 888 88 tu §O Q O O •» •» 55: 55 fclUJ UJ UJ Li) IS 33 13 i O O 00 O O _ 00 m. to wJM m\ CD CD CD CD CD CD cc; -G 88 5CM ' S 88 88! ,888 88 5050, CD CD CD 11 Sb; CD ssCD s <. o UJ Z LU < O CoC i CO 9Kg Q LU : |3 Z I CC Q o 51 O Q tr .
