i IL R Select soil samples were analyzed for total petroleum hydrocarbons as diesel (TPH-D), TPH as gasoline (TPH-G), benzene, toluene, ethylbenzene and xylenes (BTEX), MTBE, SVOCs and 17 California Assessment Manual (CAM) metals. Additionally, selected samples were submitted to the laboratory and placed on "hold" for potential analysis at a later date. These samples were ultimately not needed for analysis and were disposed of. i l 4.3 Ground Water Collection and Analysis ii f After soil borings - - - F o s SB O1 SB 02 and SB 03 were completed g p ted to depth, and the water-bearing . zone had been penetrated, the sample barrel el and inner rods were removed from the borehole F F q and one-inch diameter, Schedule 40 polyvinyl chloride (P,,VC) casing with a ten-foot section ., of 0.010-inch slotted well screen was then installed in the casing to facilitate the collection of ground water samples. The drive casing was pulled up approximately ten feet to allow ground water to flow into the boreholes. To allow for sufficient ground water recharge (within the well screen) at each location, and to allow for the collection of representative i R i ground water elevations, ground water elevations were allowed qto stabilize a minimum of one and one-half hours prior to collecting depth to ground water measurements (and prior to collecting ground water samples). Depth to round water was measured to the nearest 0.10 foot using an electronic measuring probe. Ground water;samples were collected from within the PVC casing with a one-inch diameter, stainless-steel Hailer.,F Samples were logged on a chain-of-custody document (following,the same protocol as described for soil sample collection), and delivered to Quanterra for analysis. Select ground water samples were 4 analyzed for TPH-D, TPH-G, BTEX, MTBE, SVOCs an[d dissolved 17 CAM metals. is 808-OO1.rpt104-29-971ulkeydata/reporu 10 i� • IE iE Y l}
