1 <br /> 30 March 1999 <br /> AGE-NC Project No 96-0263 <br /> Page 3 of 7 <br /> Collected samples preserved for laboratory analysis were placed in a chilled container, under ice, <br />' and transported to under chain-of-custody McCampbell Analytical, Inc , (MAI) a Sate of California <br /> Department of Health Service (DHS)-certified analytical laboratory The sampling equipment was <br /> washed in an Alconox solution and rinsed with water prior to each sampling run to avoid cross- <br />' contamination <br />' 32 SOIL LOGGING <br />' After sample preservation, soil was extruded from the remaining portions of the sleeve and was <br /> screened for organic vapor utilizing an organic vapor meter(OVM) equipped with a photo-ionization <br /> detector(PID Thermo Environmental 580A, 10 0 eV, calibrated to isobutylene), the readings were <br />' recorded on the Boring Logs The soil was visually described in accordance with the Unified Soil <br /> Classification System A soil profile is depicted in Appendix A <br />' 3 3 GRAB GROUND WATER SAMPLE COLLECTION <br /> Grab ground water samples were collected and analyzed from probe borings B1, B3, B5, B6, B7, <br /> B8 and B9, using a temporary PVC screen The probe iods were advanced to their total depth or a <br /> minimum of fifteen feet bsg The screened casing was inserted into the saturated zone Ground water <br /> was allowed to enter the casing, and samples were retrieved using a modified PVC tubing bailer <br /> After sample retrieval, the water sampler screen was disassembled and cleaned New PVC tubing <br /> was used to collect each sample Water samples were collected into 40-m1 EPA-approved VOA vials <br /> containing 0 5 ml 18% hydrochloric acid for sample preseivation The samples were placed in a <br /> chilled container under ice and transported under chain-of-custody to MAI for analysis <br /> 34 LABORATORY ANALYSIS OF SOIL SAMPLES <br /> Selected soil samples were analyzed for <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> Method 8015 Modified, <br /> • Volatile aromatic hydrocarbons (benzene, toluene, ethylbenzene and total xylenes, BTEX) <br /> in accordance with EPA Method 8020 and <br /> • Volatile organic compounds(VOCs)and oxygenated compounds(di-isopropyl ether[DIPE], <br /> ethyl tertiary-butyl ether [ETBE], methyl tertiary-butyl ether [MTBE], tertiary-amyl methyl <br /> Advanced GeoEnviron mental,Inc <br /> 1 <br />
