I <br /> 29 September 2000 <br /> AGE-NC Project No 96-0254 <br /> Page 2 of 4 <br />' ground water parameters were measured with a Hydac water analyzer Logs of the field data are <br /> included in Appendix A Purged water was stored on-site in labeled 55-gallon drums <br />' 2 2 COLLECTION AND ANALYSIS OF GROUND WATER SAMPLES <br />' Water samples were collected from each well using a new disposable plastic bailer Each water <br /> sample was transferred into one 1-liter amber bottle and three 40-ml VOA vials containing 0 5 ml <br /> 18% HCL as a sample preservative After collection, the samples were labeled and placed in a <br /> Ichilled container for transportation under chain-of-custody to McCampbell Analytical, Inc (MAI), <br /> a California Department of Health Services (DHS)-certified analytical laboratory in Pacheco, <br />' California Duplicate ground water samples collected from MW-5 and MW-6 were labeled and <br /> placed in a chilled container for transportation under chain-of-custody to Precision Enviro-Tech <br /> (PET),a California Department of Health Services(DHS)-certified analytical laboratory in Stockton, <br />' California The ground water samples were analyzed for the following <br /> • Total petroleum hydrocarbons quantified as gasoline and as diesel (TPH-g and TPH-d) in <br />' accordance with EPA Method 8015 Modified <br /> • Volatile aromatic compounds (benzene, toluene, ethylbenzene and total xylenes BTE&X) <br /> in accordance with EPA Method 8020 <br /> • Samples MW-3, MW-5 and MW-6 were analyzed for fuel oxygenates, including, di- <br /> isopropyl ether(DIPE), ethyl tertiary butyl ether(ETBE), MTBE, tertiary amyl methyl ether <br /> I (TAME) and tertiary butyl alcohol (TBA) in accordance with EPA Method 8260 Modified <br /> • Samples MW-5 and MW-6 were also analyzed for total dissolved solids (TDS) and anions <br />' in accordance with EPA methods 2540 and 300, respectively <br />' 3.0. FINDINGS <br /> 3 1 GROUND WATER ELEVATION AND GRADIENT <br />' The depths o h t ground water from wells MW-1 MW-2 MW-3 through MW-7 on-site and MW-3 <br /> gr gh <br />' from the 2420 Grant Line Road site were measured between 6 92 feet and 23 15 (MW-7) feet below <br /> the tops of well casings <br />' The ground water flow direction during this monitoring event is towards the north with an average <br /> gradient of 0 005 ft/ft in the area of the former UST area and 0 006 feet/feet to the north of the site <br /> Ground water elevation contours are illustrated on Figure 3 <br /> 1 <br /> Advanced GeoEnvironmentu!inc <br /> I <br />
