Equipment to include sufficient hollow-stem auger flights to complete each soil boring/monitor well without having to decon- taminate equipment. Depending upon type of coring equipment and casing size, augers will be either 8 1./4" OD or 10 1/4" OD. 2. Rig will be equipped with either a conventional rod driven assembly or wireline operated continuous coring device designed to hold a standard California Modified split spoon sampler. The core barrel will be thoroughly decontaminated between cores with Alconox or TSP, rinsed with clean tap water, and a final rinse with distilled or deionized water. Metal tubes used for con- taining core material will either be new or have been thoroughly cleaned prior to use. 3 After retrieving the core barrel, it will be placed on a clean surface & carefully opened. Approximately 4 ounces of the cored material will be placed in a sealed plastic bag, and set aside for 5 - 10 minutes to allow any vapors to volatize The 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_ Soil borings A & B will be advanced to within 5' of the water table, at which point a final core will be taken. While that core is being analyzed, described, & preserved, a hydropunch or BAT tool will be made up preparatory to obtaining a water sample. The tool will be thoroughly decontaminated before use as directed by the geologist in charge. It will then be lowered into the auger flights, and pushed into the soil beneath the augers far enough to penetrate the water table The tool will then be opened, and will remain open long enough to allow the collection of a discrete water sample. The tool will then be retrieved, carefully opened, and the contained water will be placed in properly treated glass vials, sealed and preserved pending transport to the laboratory for analysis_ Any remaining water will be placed in suitable containers, properly labeled, and stored on site pending laboratory results. 6. Soil borings C & D are planned to go to approximately 25' bgl or as determined by field observations It is not planned to penetrate the capillary fringe or take discrete water samples , however, equipment will be on site in the event it is decided to do so. 7
