(EA) has completed the removal of certain coal tar contaminated soil encountered at the 1 CambridgeSide Galleria site. This report describes the identification, characterization and removal of the contaminated soil. BACKGROUND On June 29, 1988 Goldberg-Zoino and Associates, Inc. (GZA) I identified a zone of potentially contaminated soil during excavation near the elevator shaft along the western edge of the Lechmere construction site (refer to Figure 1). According to specifications developed by GZA, the soil was excavated, stockpiled on and covered by polyethylene sheeting, and physically isolated from other excavated soils by a bermed area. I GZA collected samples from the suspect soil and submitted them to a certified laboratory for petroleum hydrocarbon analysis and gas I chromatography (GC) fingerprinting. The results, presented in Appendix A, indicated that the soil contained petroleum hydrocarbons in excess of 3,000 parts per million (ppm) with a GC I fingerprint similar to that of coal tar. The soil was classified by GZA as hazardous waste thereby mandating regulated off site disposal. IThe stockpile was sampled by EA on July 8, 1988 and the samples were submitted to Skinner & Sherman Laboratories for a RCRA hazardous waste characterization analysis. The waste stream I characterization analysis included tests to determine the following: leachable metals, pH, ignitability, reactivity, volatile organic compounds (VOCs), PCB concentration and semi- i volatile organic compounds.

Ignitability (flash point) of the sample exceeded 200OF and the I pH value of 7.85 is within the range for urban environments. The analysis indicated the presence of semi-volatile compounds typically associated with coal tar, however, the soil was not a federally listed hazardous waste or hazardous by characteristic. 1 The soil was considered a hazardous waste in Massachusetts due to the concentration of petroleum hydrocarbons. On August 1, 1988 an additional pocket of coal tar contaminated soil was encountered during excavation associated with the elevator shaft construction. Per the project specifications, I this material was separately stockpiled on and covered by polyethylene sheeting, and was physically isolated from other excavated material by a bermed area. Subsequent laboratory I analysis performed by Skinner & Sherman Laboratories, presented in Appendix C, indicated contaminant type and concentrations similar to the previously identified contaminated soil. This additional volume of soil was classified in the same manner as * the previously excavated coal tar contaminated soil. CONTAMINATED SOIL DISPOSAL U From October 28 to November 10, 1988, the stockpiled contaminated soil was loaded and transported off site to a lined landfill. Licensed hazardous waste transporters were used to deliver thirty four vehicle loads of contaminated soil to Chemical Waste Management (CWM) Chemical Services, Inc. in Model City, New York. Vehicle loading was conducted by the site excavation contractor, A.J. Welch, under the direction of EA's Environmental Specialist, Mr. Stephen Hamburger. I Based on actual weight measurements of vehicle loads, (Appendix D), 629.68 tons of coal tar contaminated soil were transported to CWM Chemical Services, Inc. Landfill. Appendix E contains Scompleted copies of the Uniform Hazardous Waste Manifest for each load. EA has mailed the appropriate copies of the waste manifests to the designated states on behalf of Lechmere.

APPENDIX A ANALYTICAL DATA Erco Laboratory I TEnseco I July 11, 1988 I I Mr. Ted Pickering Goldberg-Zoino & Associates, Inc. 320 Needham Street Newton, MA 02164 Dear Ted: Enclosed are the results of the analyses performed on the one soil sample for Lechmere at Cambridgeside Galleria, Cambridge, MA (Project No. J-7088.8; Purchase Order No. 25092). This project was I received under chain of custody at Enseco - Erco Laboratory on June 30, 1988, and was processed for a one-week turnaround time. A brief description of the Quality Assurance/Quality Control and methods employed iby Enseco are contained within the report. This letter authorizes the release of the analytical results and should be considered an integral part of this report. Please refer to this project by the Erco Laboratory Identification 1 No. 8352 to help expedite any future discussions. We will be happy to answer any questions or concerns that you may have. Sincerely, I 6 Clyde E. Tressler I Client Service Representative I 12 Thomas R. Copeland, Ph.D. I Technical Director Encl.

Reagent or analytical blanks are analyzed to assess the level of contamination which exists in the analytical system. An analytical blank, analyzed with every batch of samples, consists of reagents specific to the method. This blank is carried through every aspect of the procedure, including preparation, cleanup, and I analysis. Ideally, the concentration of an analyte in the blank is below the reporting limit for that analyte. However, some common laboratory solvents and metals are difficult to eliminate to the part-per-billion levels commonly reported I inenvironmental analyses. Therefore, analytical data are corrected for blank contamination before they are reported to the client. 3Laboratory control samples (LCS) are used to monitor the laboratory's day-to- day performance of routine analytical methods. An LCS consists of a standard, I control matrix which is spiked with a group of target compounds representative of the method analytes. The LCS is analyzed with environmental samples to provide evidence that the laboratory is performing the method within accepted QC I guidelines. An LCS has been established for most routine analytical methods. Reagent I water is used as the control matrix for the analysis of aqueous samples. The LCS compounds are spiked into reagent water and carried through the appropriate steps of the analysis. As stated in SW-846 (third edition), a universal blank matrix Sdoes not exist for solid samples and therefore no matrix is used. The LCS for solid samples consists of the LCS compounds spiked into a reagent blank and carried I through the appropriate steps of the analysis. The data thus obtained are used to set the LCS control limits. As sufficient laboratory data become available, the control limits are redefined based upon the most recent six months of LCS data. E Control limits for accuracy are based on the historical average recovery of the LCS plus or minus three standard deviation units. I Surrogates are organic compounds that are similar to the analytes of interest in chemical behavior but which are not normally found in environmental samples. Enseco routinely adds surrogates to samples requiring GS/MS analysis and reports these surrogate recoveries to the client. These surrogates are added to samples to monitor the effect of the matrix on the accuracy of the analysis. Results are I reported in terms of percent recovery.
