�I • Collection of soil samples and classification by ASTM D-2488 • Preparation of Boring Logs (refer to Plates 1 thru 13) • Proper containment and labeling of soil cuttings, equipment rinsate and purged groundwater • Preparation of this Data Report to be submitted to Remediation Services. The locations of borings B-101, B-102, B-103 and B-104 are presented on Figure 2, Site Plan I Drilling was accomplished with a Mobile Drill B-53 truck-mounted rig with 8-inch hollow stem I auger. Samples were collected at ten-foot intervals from depths of ten feet to forty-five feet { whereupon samples were collected at approximately five-foot intervals to a depth of 75 feet. The soil samples were collected by driving a two-inch I D sampler fitted with stainless steel liners I18 inches into relatively undisturbed soil The ends of the retained sample were covered with Teflon' film and plastic caps The retained soil samples were stored in a cooler with ice until I delivery to the BSK analytical laboratory The samples were shipped in a cooler with dry ice ` under Chain-of-Custody protocol (see Attachment A) Augers and drill rods were cleaned with a high-pressure, high-temperature cleaner before, between and after each bore hole The equipment was washed in a polyethylene lined containment basin The rinsate from the auger wash was placed into 55-gallon DOT 17 E/H drums and labeled. ISoil cuttings from the borings were contained in 55-gallon DOT 17 E/H drums and labeled Upon completion of the borings, the bore holes were backfilled with neat cement using a tremae method. I4.0 QUARTERLY GROUNDWATER SAMPLING Prior to sampling, the depth to water in the well was measured utilizing an electric sounding tape. The well was then purged of at least three well volumes Purging was accomplished by use of a bladder pump After removal of each well volume, parameters were measured utilizing a field meter The parameters measured included pH, conductivity and temperature Consistency of these measured properties indicate that fresh water is being drawn from the aquifer A well field log was maintained during the purging and sampling activity (sec Well Field Log presented on Plate 14) 3 •ssociates
