Mi Ron Rowe Apid 30, 1998 CAMBRIA . Well Materials Well MW-1 was constructed using two-inch diameter, schedule 40 PVC well casing and 0 010-mch slotted well screen (Attachment B) Screened Interval Well MW-1 was screened from 13 5 to 33 5 ft below grade (Attachment B) Well Development The monitoring well will be developed, purged, and sampled by Blame Tech Services, Inc (Blaine) of San Jose, California during April 1998 The SJCPHS will be given 48-hour notice before the well is developed Soil Chemical Analyses Based on Cambna's work plan and field observations, soil samples from the following depths were selected for chemical analysis 5 5'-6 5', 20'-21 5', 23 5'-24 5', 27 5'-29', and 33 5'-35' The soil samples were analyzed for • Total Purgable Petioleum Hydrocaibons (TPPH) by modified EPA Method 8015, • Benzene, toluene, ethylbenzene and xylenes (BTEX) by EPA Method 8020, • Methyl tort-Butyl Ethel (MTBE), Tertiary Amyl Methyl Ether (TAME), di-Isopropyl Ether(DIPS), Ethyl tent-Butyl hthey(ETBE), tort-Butanol, and ethanol using EPA Method 8260, and, • Methanol by modified EPA Method 8015 Soil Physical Analyses Based on Cambria's work plan and field observations, soil Samples from the following depths were selected for physical analysis 9 5'-11', 25'-26', and 32 5'-33 5' The soil samples were analyzed for permeability, poiosity, density, and organic carbon content Ground Water Analyses The grab ground water sample was analyzed for • TPPH by modified EPA Method 8015, • BTEX by EPA Method 8020, • MTBE, TAME, DIPS, ETBE, tert-Butanol, and ethanol using EPA Method 8260, and, • Methanol by modified EPA Method 8015 Soil Disposal Soil cuttings produced from the well installation were stockpiled and sampled for disposal Upon review of the analytical results, Shell will arrange for transportation of the stockpile to an approved disposal/recycling facility 0 3
