Selected soil samples will be transported to a State-certified laboratory and analyzed for total <br /> petroleum hydrocarbons quantified as diesel (TPH-d) and volatile aromatics (benzene, <br /> toluene, ethyl benzene and total xylenes: BTE&X) in accordance with the appropriate EPA <br /> methods. Additionally, selected soil samples will be analyzed for pH, dry bulk density, <br /> moisture content, porosity and fractional organic content by the appropriate ASTM methods. <br /> 4.2. COLLECTION OF STOCKPILE SOIL SAMPLES <br /> For the collection of soil samples from the excavated soil, both stockpiled at the south end of the <br /> property and in the former excavation area, the following procedures will apply: <br /> 1. Notify the PHS-EHD 48 hours prior to commencement of any work. <br /> 2. Collect approximately (10) soil samples from the existing stockpiled soil at the south end of <br /> the property and five (5) additional soil samples from the upper soils within the backfilled <br /> excavation. All soil samples will be collected with a metric soil sampler, pre-loaded with two <br /> clean, 2- by 3-inch brass sleeves. The proposed stockpiled soil sample locations are depicted <br /> in Figure 2. <br /> 3. Decontaminate all sampling equipment in an alconox solution and rinse twice with water prior <br /> to each sampling event. <br /> 4. Preserve soil in the brass sleeve by covering both ends with Teflon sheets, capping, and <br /> sealing with tape. <br /> 5. Store the samples under ice and transport the samples in a chilled ice chest to a State-certified <br /> laboratory for analysis. <br /> 6. Screen soil samples for the presence of volatile organics (if necessary) using a photo- <br /> ionization detector (FID) pre-calibrated to isobutylene. <br /> 7. Soil samples will be analyzed for TPH-d and BTE&X in accordance with the appropriate <br /> EPA methods. <br /> 4.3. REPORTING <br /> A report detailing the results of the investigation will be prepared. The report will be in a format <br /> acceptable to the PHS-EHD and CVRWQCB. The report will be reviewed and signed by a California <br /> Registered Geologist. <br />
