These <br /> samples were collected during a follow-up drilling program after <br /> a geotechnical engineer reported the presence of hydrocarbonsin <br /> the soil and shallow groundwater during foundation test drilling. <br /> Thorne Environmental, Inc. was subsequently requested to assist <br /> King Island Resort personnel in assessing the presence of the <br /> hydrocarbons. <br /> Grab soil and groundwater samples were collected from the . two <br /> y <br /> boreholes in samples containers provided by the laboratory. The <br /> samples were labelled, placed in an ice filled chest and were <br /> delivered under appropriate chain of custody to Anlab Laboratory, <br /> a State certified laboratory. The soil and groundwater samples <br /> were analyzed for Total Petroleum Hydrocarbons using a modified <br /> Method 8015 and for BTXE (benzene, toluene, xylene, and <br /> ethylbenzene) using Methods 8020 and 602 respectively. It was the <br /> intent of the sampling to confirm the presence or absence of <br /> petroleum hydrocarbons, rather than to identify the source of the <br /> product. <br /> Independent of the soil sampling, the domestic well which services <br /> the property had been sampled on March 27, 1989 by California Water <br /> Labs and analyzed for bacteria, inorganics, organics, general <br /> physical, general mineral, and the Title 22 constituents. This <br /> well is located approximately 100 feet away from the nearest soil <br /> boring. The results of this water analysis are attached and <br /> document that no BTXE or other fuel compounds are present in the <br /> drinking water source. <br /> __- There-are three--(3)-underground-tanks on-the-subi ect--property;- one <br /> 6000 gallon leaded, one 2000 gallon unleaded, and one 4000 gallon <br /> diesel (see attached figure) . The tanks and lines of all three <br /> tanks were last tightress tL-sted on July 26, 1988. No leaks were <br /> reported during those tests. Because of the recently discovered <br /> �... hydrocarbons found on the property, the tanks and lines have been <br /> scheduled for a retest at 8:00 a.m. on Thursday, May 11, 1989.
