WHF Environmental Consultants,Inc. <br /> Sampling Protocol <br /> A . <br /> Drilling <br /> r <br /> Permits were obtained for the boring and monitoring well before the drilling <br /> began. The soil borings were accomplished using a mobile mounted drilling rig <br /> 4{ employing the use of a hollow stem flight auger no less than 3 1/4-inch i.d. and <br /> 8 7/8 o.d. <br /> f <br /> All drilling equipment was thoroughly steam-cleaned before drilling began to <br /> prevent the introduction of contamination from off site and between borings to <br /> pmvent cross contamination. <br /> i � <br /> g ' The borings were logged (Appendix A) under the direct supervision of a <br /> registered engineering geologist using the Unified Soil Classification System. <br /> The color, texture, moisture, plasticity(if applicable), consistency of the earth <br /> materials,pertinent soil or bedrock characteristics,and any evidence of <br /> contamination was noted. All water-bearing zones and the depths at which they <br /> were encountered were noted onthese logs. <br /> All borings were drilled in such a manner as to prevent cross contamination <br /> r� <br /> between strata. Exploratory soil borings within the unsaturated zone were <br /> backfilled with a 5% bentonite and cement grout with a bentonite plug at the <br /> base. <br /> E.3 <br /> The cuttings from the drilling operation were contained on-sits during drilling <br /> for proper disposition. The proper method of disposal is dependent upon results <br /> of laboratory analysis. This disposal will be the responsibility of the client <br /> unless other arrangements have been made. <br /> Well Consmcrion <br /> All materials used in well construction were thoroughly cleaned prior to <br /> introduction into the boring.
