(BEM) herein presents its Preliminary Draft Summary of Findings from the <br /> Limited Phase II Groundwater Investigation conducted by BEM at the R. M. Holz Rubber Co., Inc. (Holz)facility <br /> located in Lodi, California. <br /> Groundwater sampling was conducted at the subject property on 18, 19 and 20 September 1996. The objective of <br /> the sampling was to evaluate water quality in the uppermost portion of the regional groundwater table. To-date, <br /> the scope of services has included: utility clearance, subsurface drilling permit procurement, drilling and <br /> installation of five (5) temporary wells, groundwater sampling and analysis, analytical services procurement and <br /> management,data management,and data evaluation. <br /> The groundwater sampling and analysis plan(SAP)is included as an attachment to this report;minor deviations in <br /> approach and sampling locations will be presented in the complete version of this report. Five groundwater <br /> samples, collected from each of the temporary wells, were submitted to Inchcape Testing Services (ITS) <br /> Environmental Laboratories, Inc. of Dallas, Texas, a California certified laboratory, and were analyzed for full <br /> target list analytes (see attached groundwater SAP for specific analytical scope and methodologies). <br /> Comprehensive Analytical Data Summary Tables are provided as an attachment to this report. <br /> Based on the data, it is indicated that: three (3) of the five (5) groundwater samples collected at the subject <br /> property contain elevated concentrations of trichloroethene (TCE) and tetrachdoroethene (or perchlorethylene <br /> [PCE]). TCE and PCE in sample B-1 (25.2 micrograms per liter [ug/L] and 53.1 ug/L, respectively) and sample <br /> B-2 (414 ug/L and 17.7 ug/L, respectively)and TCE in sample B-3 (7.6 ug/L) were detected [substantially] above <br /> (up to a factor of 83 times above)the USEPA/California State Maximum Contaminant Levels(MCLS)for drinking <br /> water(5 ug/L of TCE and/or PCE). The presence of TCE and PCE in groundwater is consistent with the detailed <br /> investigation of the"Lodi Groundwater Site" that has been conducted by the California Environmental Protection <br /> Agency(CAL/EPA)Department of Toxic Substances Control(DTSC). <br /> As documented in Northeast Research Institute LLC's (CAL/EPA contractor's) Final Summary Report entitled <br /> "Potential Responsible Parties Search and Sources Investigations, Lodi Groundwater Site, Lodi, California," <br /> drinking water supply wells within the 600-acre area of investigation have been contaminated with the same <br /> chlorinated solvents(TCE and PCE)as those that were detected at the subject property. PCE is primarily used as a <br /> cleaning agent by the dry cleaning industry and TCE is most often used as a degreasing solvent by manufacturing <br /> and metal finishing industries;groundwater contamination in this region is attributed to the waste disposal <br />
