Roy's Towing <br /> Page 4 <br /> The small sump inside the building will be investigated by a hand auger boring indentified on <br /> Figure 2 as location "E". Soil samples will be collected at depths of 1 foot and 5 feet below the <br /> bottom of the sump. <br /> Soil samples will be collected at depths of 1 foot and 5 feet below the drain line/leach line at <br /> the locations identified on Figure 2 as "F" and "G". <br /> A soil boring will be drilled with a hollow stem auger drill rig beside the leach field seep pit as <br /> shown on Figure 2 (location "H"). Samples from the depths of 27, 35 and 40 feet will be <br /> submitted to the laboratory. Analysis of the two deeper samples will be contingent upon the <br /> analytical results of the sample collected from 27 feet. <br /> Sampling locations "I", "J" and "K" are randomly placed throughout the uninvestigated portion <br /> of the property. Samples at these locations will be collected at depths of 1 foot and 5 feet. <br /> Sample Collection Methodology <br /> The samples to be collected from beneath the sump (location E) will be obtained with a hand <br /> auger and drive sampler attachment. Soil samples from all outdoor locations except for location <br /> "H" will be collected using a backhoe to open small trenches to a depth of 5 feet. Brass soil <br /> tubes will be driven into the sides or floor of the trenches at depths of 1 foot and 5 feet in order <br /> to collect the samples. Should any of the proposed sampling locations be inaccessible to the <br /> backhoe, a hand auger/drive sampler will be used. <br /> The soil boring to be advanced next to the seepage pit will be drilled using a hollow stem auger <br /> rig. Soil samples will be collected at five foot intervals for classification and field screening <br /> purposes. Three samples will be submitted to the laboratory for possible analysis. Inasmuch <br /> as the seepage pit is 25 feet deep, it is expected that the samples submitted will be from the <br /> depths of 27, 35 and 40 feet. <br /> Laboratory Analysis <br /> Selected soil samples will be analyzed by a State-certified laboratory. All samples from the <br /> sump/leachline investigation (locations E, F and G), the 1-foot-bgs soil samples from other <br /> locations and the sample collected from the drilled boring (location H) at 27 feet bgs will be <br /> analyzed for TRPH using EPA method 418.1 and total lead using EPA method 6010. If total <br /> lead is detected at concentrations between 50 and 1000 parts per million, soluble (STLC) lead <br /> will be analyzed. The samples collected from the sump/leachfield and seepage pit area will also <br /> be analyzed for HVOCs using EPA method 8010. <br /> groundu\roysmp <br />
