present at 3 feet , becoming light olive-brown at 6 feet <br /> feet , and olive at 8 ft . The soil was damp at 3 ft , and at <br /> 6 ft , and moist at 8 feet . Soils were stiff between <br /> approximately 1 ft and 7 ft , and soft at 8 ft . A slight <br /> ' odor , consistent with that of fuel hydrocarbons , was <br /> present in the sample acquired at 8 feet 40 parts per <br /> million (ppm) combustible vapors were also present in this <br /> ' sample Groundwater was encountered at approximately 9 <br /> feet A slight odor, also consistent with that of fuel <br /> hydrocarbons , was present in the moderately turbid grab <br /> water sample acquired from SBR-5 <br /> The soil profile encountered while advancing boring SBR-6 <br /> consisted of 3 inches of asphalt underlain by inorganic , <br /> ' slightly moist , gray-black clay exhibiting an odor <br /> consistent with that of oil to 1 foot . Slightly moist , <br /> inorganic dark-colored clay was present to 2 feet . This <br /> ' was underlain by slightly moist , plastic , inorganic light- <br /> brown clay to approximately 4 5 feet . Slightly moist, <br /> inorganic brown clay with greenish streaks was present <br /> between approximately 4 . 5 and 6 5 feet . A faint gasoline- <br /> like odor was present in this layer Moist , inorganic <br /> olive-colored clay was encountered between approximately <br /> 6 5 and 8 5 feet . A gasoline-like odor was also present in <br /> this interval Water saturated, dense, brownish silty clay <br /> was present between approximately 8 5 and 9 feet <br /> Imported gravel fill was encountered immediately beneath 3 <br /> ' inches of asphalt at SBR-7 Although efforts were mae to <br /> made to advance the boring through the gravel , the hole <br /> would not remain open and the boring was abandoned, In <br /> ' consideration of observations made at other borehole <br /> locations and the proximity of borings SBR-3 , SBR-4 , SBR-8 , <br /> and SBR-10 to SBR-7 , it is proposed that SBR-7 be deleted <br /> t from the drilling schedule . Should PHS/EHD advise upon <br /> review of this report that they wish samples acquired from <br /> SBR-7 , EPM will return to the site and acquire samples by <br /> excavating <br /> 1 The soil profile encountered while advancing boring SBR-8 <br /> consisted of 3 inches of asphalt underlain by sand and <br /> ' gravelly fill to 1 foot Light olive-brown sandy clay was <br /> present at 3 feet , becoming olive at 6 feet feet and 8 ft <br /> The soil was damp at 3 ft , moist at 6 ft , and wet at 8 <br /> ' feet Soils were stiff between approximately 1 ft and 5 <br /> ft , firm between approximately 5 ft and 7 ft , and soft <br /> between approximately 7 ft and 10 ft . A slight odor , <br /> consistent with that of fuel hydrocarbons , was present in <br /> the samples acquired at 6 ft and 8 feet . 30 parts per <br /> million (ppm) combustible vapors were present in the sample <br /> acquired at 8 feet Groundwater was encountered at <br /> approximately 8 feet A slight odor , also consistent with <br /> that of fuel hydrocarbons , was present in the moderately <br /> Page 6 <br />
