INVESTIGATION STATUS AND RESULTS <br /> AEMC was hired by Beck Development on August 5, 1986, to confirm <br /> or deny the presence of the concrete impoundment and to take soil <br /> samples to determine if any contamination exists . <br /> The impoundment was initially located by superimposing the 1953 <br /> air photograph onto an existing site map, shown on figure 1. In <br /> August 1986, using this site map, AEMC had the impoundment <br /> location determined by Dick Cecchi, a licensed surveyor with <br /> George S. Nolte and Associates. The perimeter of the impound— <br /> ment, the four quadrants of the impoundment, and the center of <br /> each quadrant were all located. These locations were marked on <br /> the ground surface by stakes . <br /> On September 2, 1986, AEMC drilled five borings at the site at <br /> the locations shown on figure 1. Boring logs are included as <br /> Appendix 1. These borings were drilled with a hollow stem auger <br /> until drilling was prevented by concrete, thus confirming the <br /> presence of the impoundment. Concrete was encountered from 7.0 <br /> to 8.5 feet below the surface . <br /> Soil samples were taken at various depths in each boring (see <br /> Appendix 1). Petroleum odors were detected from samples taken at <br /> 5.5 to 8 feet in the 3 southernmost locations, BB, C and D. All <br /> samples taken were transported, on ice, to Eureka Laboratories <br /> for analysis or storage. The samples which gave off petroleum <br /> odors, and the deepest samples from borings A and B were selected <br /> A <br />
