0 • <br /> Description and Identification of Sods) One brass sleeve with soil from each interval <br /> will be capped, sealed, labeled in accordance with EPA protocols, recorded on a <br /> chain-of-custody form, placed in a cooler at 4° centigrade or less, and transported to a <br /> California Certified Laboratory with the chain-of-custody for the specified analyses <br /> 43 Feld Screening of Soil Samples <br /> Soil samples will be collected using three six-inch brass tubes installed inside a <br /> split-spoon sampler The middle sample tube will be immediately capped and stored <br /> in an iced cooler upon collection The bottom tube will be used for lithologic <br /> description, and the top tube will be used for field screening The material from the top <br /> tube will be placed in a mason lar to approximately 50 percent capacity, shaken, and <br /> stored for a period of 15 minutes. A standard headspace reading will be collected at <br /> this time and noted on the boring log Field screening will be accomplished using a <br /> Foxborough 128 GC/OVM flame-ionizing detector <br /> 4.4 Soil Analyses <br /> Approximately thirty (30) soil samples will be analyzed by Smith Emery <br /> Company, a California State Certified Laboratory in accordance with state guidelines <br /> and EPA protocols <br /> The samples will be analyzed for fuel hydrocarbons as gasoline and volatile <br /> aromatics using DOHS LUFT/EPA Methods 8015 modified and 8020, respectively. <br /> The detection limits for TPH as gasoline will be 0 5 mg/kg and for BTEX the detection <br /> limas will be 0 005 mg/kg <br /> 45 Report of Findings <br /> A report of findings will be prepared which will detail field activities, analytical <br /> results, discussion of analytical results, conclusions and recommendations The <br /> recommendations section will include a brief analysis of at least three mitigation <br /> alternatives, if mitigation of the site is required The report of findings will be certified <br /> by a California Registered Geologist. <br /> 50 Quality Assurance Plan <br /> This section describes field and analytical quality-assurance procedures to be <br /> followed during the investigation and remediation <br /> 51 Sample Collection and Handling Protocol <br /> Proper sample collection and handling are essential to assure quality of data <br /> obtained from a sample Each sample, therefore, will be collected in a brass tube, <br /> • preserved correctly for the intended analysis and stored for no longer than permissible <br /> 6 of 12 <br />
