1 <br /> City of Stockton Redevelopment Agency B34604.01a <br /> ' February 16, 2001 Page 6 <br /> groundwater sample analytical results are expected to provide data on the possible presence of <br /> ' chlorinated solvents in groundwater beneath the SITE. This data may also be used to evaluate <br /> potential remediation methods. <br /> Soil cuttings from the monitoring well borehole,rinsate from the decontamination of drill tools,and <br /> purge water will be sealed in United States Department of Transportation(DOT)-approved drums <br /> labeled and stored in a secured location. Based on the characterization of the soil Twining will <br /> ' recommend an appropriate method for disposition of the cuttings based on the analytical results. <br /> Disposal will be the responsibility of the client. <br /> 4.3 Laboratory Testing Program Selected soil and groundwater samples collected from the <br /> SITES will be chemically analyzed in the laboratory. Proposed preparation and analytical methods <br /> for the laboratory analyses and corresponding method detection limits are summarized in Table 1. <br /> TABLE 1 <br /> ' PROPOSED PREPARATION AND ANALYTICAL METHODS <br /> Analytes Preparation Analytical DLR <br /> Method Method mg/kg <br /> Soil Sample Analyses <br /> Total Recoverable Petroleum Hydrocarbons(TRPH) 5520F 552OF 10 <br /> Metals: Cadmium(Cd),Chromium(Cr),Lead(Pb), 6010 6010 5 <br /> Nickel(Ni),and Zinc(Zn) <br /> Ethylene Glycol 8015B 8015B 1 <br /> Groundwater Sample Analysis <br /> Chlorinated Solvents 8260 8260 5 <br /> mg/kg = milligrams per kilogram <br /> DLR = Detection limit for reporting purposes <br /> Twining is a California Department of Health Services certified hazardous waste laboratory <br /> ' (Certificate No. 1371) for the analyses outlined herein. A description of laboratory quality <br /> assurance/quality control procedures proposed for the analyses are described in the SOPs presented <br /> in Appendix A. <br /> 4.4 SummaEy Report: Upon completion of field and laboratory activities, a summary report <br /> will be prepared presenting results and findings (including the final logs of soil borings and <br /> laboratory analytical reports). The report will include an evaluation of the findings and <br /> recommendations for either; further site assessment, remedial action, or a statement of"no further <br /> action necessary" as appropriate. <br />
