a eolo icaC7eies Inc. cfm Fiore Development Soil&Groundwater Report April 19, 1999 1.2 Soil Laboratory Analyses Two soil samples and the groundwater sample were submitted to Kiff Analytical of Davis and tested for the following analysis: • Benzene, Toluene, Ethylbenzene and Xylene (BTEX) by EPA method 8020 • Gasoline (TPH-G)by EPA method 5030/8015(m) r • The oxygenated fuel compounds (MTBE, DIPS, ETBE, TAME, TBA) by EPA method 8260 • EDB & EDC by EPA method 8260 1.3 Site Geology The geologic log prepared during drilling of this borehole is attached. The subsurface geology is primarily fine to coarse grained sand. A silt layer was encountered from 13 to 16 feet bgs. The excavation backfill extended down to 9 feet bgs. Groundwater was encountered at 16 feet. 1.4 Distribution of Contaminants I Laboratory tests show that the soil samples collected from 10 and 15 feet bgs and the groundwater sample collected from 17-20 feet bgs.,.were non-detect for all analytes. Observations in the field by OVM. and sensory queues corroborates with the lab data and I shows contamination is not present in the soil samples collected from the surface to 18 feet j bgs. 2.0 CONCLUSIONS The following conclusions can be made: • The laboratory test results show that the soil and groundwater beneath the tank pit are not impacted by gasoline compounds. • No further investigative activities should take place at this site and it should recive a letter of closure. L 3.0 LIMITATIONS This report was prepared in accordance with the accepted standards and practices of the field of environmental geology, groundwater hydrology and good business practices. It should be recognized that definition and evaluation of environmental conditions is a difficult and inexact science. Judgments leading to conclusions and recommendations are generally made with an incomplete knowledge of the site-specific conditions present. The tasks proposed and completed during this project were reviewed and approved by the local regulatory agency for`compliance with the law. No warranty, expressed or implied, is made.
