probe of a properly field calibrated PID meter will be inserted into the bag; any readings will be recorded on appropriate forms . 4 The retrieved core will be quickly described, and the ends of one metal tube promptly covered with teflon tape & plastic end caps , thoroughly sealed with duct tape, labeled, & placed on ice pending transport to a State certified laboratory for analysis All unused core material & drill cuttings will be placed in properly labeled drums, firmly sealed, and stored on site pending results of laboratory analysis . 5 The monitoring wells will be drilled & sampled in the same manner as the soil borings down to the water table . After obtaining a core from the capillary fringe, each well be advanced to a minimum of 10 feet into the aquifer preparatory to com- pleting as a groundwater monitoring well . Recent data indicates that the water table is about 25 ' bgl . 6 After augering operations are completed, and depth to water has been verified, 2" or 41, internal flush, screw-3oint blank & slotted PVC casing will be installed, sand packed, sealed & grouted as shown on the attached schematic, EXHIBIT B. The top of the perforated screen will extend a minimum of 10 ' above & 10 , below, the water table. 7 Each well will be fitted with a preformed surface vault, thoroughly cemented in place, casing will extend into vault a sufficient distance to allow installation of an expandable locking cap. The casing will be notched on the north side to facilitate measurements A metal cover rated for heavy traffic will be securely attached to the vault ; it will be properly identified for future reference 8 . Drill solids & unused core material will be placed on plastic in a remote location on the property and covered with plastic pending the results of soil analyzes . 9 After completion of augering operations, the preserved soil & water samples will be transported under proper chain of custody to a State certified testing laboratory with instructions to analyze soil samples for BTEX (EPA 8020, ) TPH-G (EPA 5030/8015M, ) and TRPH (EPA 3540/8015M ) 10 Within 18-24 hours after completion, each well will be developed by swabbing with a hard rubber disc or suitable device for at least 15 minutes, or until returns are clear Fluids removed will be placed in properly labeled drums, securely sealed & stored on site Method of disposal of contents will depend 7
