• 2 2 1 Soil Sampling and Analysis <br /> During drilling, soil samples were collected from each soil boring at 5-foot intervals using a modified <br /> California split-spoon sampler lined with brass sleeves A field geologist logged all soil samples for <br /> hydrogeologic and lithologic characteristics according to the Unified Sod Classification System and <br /> screened each sample for any hydrocarbon vapors using an organic vapor monitor, equipped with a <br /> photoionization detector (PID) The soil boring for MW-2 was continuously cored for detailed <br /> logging and soil sampling Soil samples from the continuously cored soil boring were collected by <br /> manually filling a brass sleeve with the cored soil The sod boring and monitoring well logs are <br /> included as Appendix A <br /> Two soil samples from each of the 6 soil borings were selected for laboratory analysis The soil <br /> sample selection was reviewed with PHSIEHD, prior to laboratory submittal The selected soil <br /> samples were packaged in an iced cooler and transported under chain-of-custody documentation to <br /> American Environmental Network (AEN), a state of California-certified hazardous waste testing <br /> laboratory (DOHS #1172) AEN analyzed each of the soil samples on a standard turn-around time <br /> of 7 working days for TPH-as-diesel, TPH-as-gasoline, BTEX and MTBE by Modified EPA Methods <br /> 8015 and 8020 AEN also analyzed 2 of the soil samples for Total Organic Carbon and 2 of the soil <br /> samples for Total Lead <br /> • Two soil samples were also analyzed for physical parameters by BSK &Associates (BSK) BSK <br /> tested the sod samples for permeability, porosity, dry bulk density and moisture <br /> 2 2 2 Groundwater-Grab Sampling and Analysis <br /> At the top of the groundwater-bearing zone in each of the three, 6-inch diameter soil borings (SB-5, <br /> SB-6 and SB-7), a push driven groundwater sampling device (Hydropuncho) was deployed From <br /> the Hydropuncho, groundwater-gran samples were collected using a bailer <br /> Each of the groundwater-grab samples were analyzed by AEN on a standard turn-around time 7 <br /> working days for TPH-as-diesel, TPH-as-gasoline, BTEX and MTBE by Modified EPA Methods <br /> 8015 and 8020 <br /> Fallowing the groundwater-grab sampling, each of the 3 soil borings not to be converted to <br /> monitoring wells (SB-5, SB-6 and SB-7) was sealed with neat cement, placed by the tremae method <br />
