The soil conditions from B-4 were similar to borings B-1 and B-3 and consisted of clayey and sandy silt from approximately 4 feet BG to 20 feet BG. No odors or soil dis-colorization was noted in the borehole. Groundwater was not encountered. Soil boring B-5 was also advanced inside the J.F. Donaldson Tire Shop at 240 North Hunter Street and approximately 20 feet south of the onsite underground hoist. B-5 was advanced to approximately 20 feet BG and was sampled continuously beginning at approximately 4 feet BG. The boring was advanced through a 6-inch diameter concrete core hole that extended approximately 6-inches BG. Soil samples were collected continuously for evaluation from approximately 4 feet BG to approximately 20 feet BG. Soil samples were collected from the boreholes using a 2-inch diameter, 4-foot long acrylic sample tube. The sample tube was placed inside a drilling rod and driven into the soil at the desired sampling depths. Upon sample collection the samples selected for chemical analysis were cut from the acrylic tube and lined with non-adhesive Teflon tape and plastic caps and then labeled and placed under refrigerated conditions pending laboratory chemical analysis. The soil conditions from B-5 were similar to borings B-1, B-3, and B-4 and consisted of clayey and sandy silt from approximately 4 feet BG to 20 feet BG. No odors or soil dis-colorization was noted in the borehole. Groundwater was not encountered. After the soil samples had been retrieved, sealed, recorded and placed in the cooler pending analysis, and after Mr. Johnny Yoakum from San Joaquin County Environmental Health Department arrived onsite, the borings were grouted using a Portland cement bentonite grout mixture in accordance with local and State guidelines. The grout extended from the bottom of the borehole to within approximately 6-inches of the ground surface. The remaining 6-inches was filled with concrete or asphalt, as appropriate. 4
