1 <br /> some solvents, and chlorinated compounds According to Vironex, soil samples which are <br /> prepared by EPA Method 5035 and analyzed by EPA Method 8260 with MIP responses <br />' The attached Vironex report (Appendix C) includes graphs showing empirical correlations of <br /> Vironex measurements and from lab measurements using USEPA SW-843 methods <br /> 2.3 Direct-Push Sample Collection and Analysis <br /> p Y <br />' Intact soil was collected from Borings DP-4, DP-6, DP-8 and DP-9 using a Geoprobe° <br /> Sampling locations and specific depths were based on MIP contamination information Discrete <br /> samples were submitted for laboratory analysis, from each of these borings Soil from <br /> Boring DP-9 was also lithologically logged At the completion of sampling all borings were <br /> backfilled with neat cement grout to slightly below existing grade at the client's request <br /> A groundwater sample was collected from boring MIP-1B at a depth of 24-27 feet bgs using <br /> HydroPunch equipment with a four-foot screen The sample possessed a very strong odor of <br /> hydrocarbons when retrieved from the boring Groundwater sample collection was attempted at <br /> boring MIP-3 at two screen intervals, 28-31 ft bgs, 24-27 ft bgs but samples were not collected <br /> because water did not enter the screen in either depth Direct-push groundwater results are <br /> shown in Table 1 and direct-push soil results are shown in Table 2 <br /> All soil and groundwater samples were analyzed for concentrations of <br /> * Total Petroleum Hydrocarbons calculated as gasoline (TPH-g), <br /> o Total Petroleum Hydrocarbons calculated as diesel (TPH-d), <br /> o Total Petroleum Hydrocarbons calculated as waste oil (TPH-wo), <br /> e Benzene, Toluene Eth lbenzene and Xylenes (BTEX compounds), <br /> ), <br /> Volatile Organic Compounds (VOCs) by U S Environmental Protection Agency <br /> (EPA) Methods 8015Mod and 8260B <br /> A copy of the analytical report is included in Appendix D, "Site Investigation Certified <br /> Analytical Report, Field Documentation, and Chain-of-Custody Documentation" <br /> 2.4 Groundwater Monitoring Well Sampling and Analysis <br /> Groundwater samples were collected from site wells MW-4RD, MW-4RS, MW-1RD, VW-2 and <br />' VS-3 on May 18 and tested for the following noncontarrunant parameters <br /> Total Alkalinity <br /> s Bicarbonate (CaCO3 ) <br /> N 78chPub4120221 Don Aod nLRpb6JRlSpm g 2006 SIR{AugusO cbc 2-2 <br />
