SOIL SAMPLING <br /> Soil samples for Tank #2 will be taken at 5.0' intervals starting at a bore hole depth of 10.0'. <br /> Standard BX tube samples will be taken from a eight itich hollow stem auger. Push point drilling <br /> may also be used for soil sampling. Each soil tube will be capped with a layer of aluminum foil <br /> secured by plastic caps, sealed with duct tape, labeled for identification, and stored on ice for <br /> transport to the laboratory. All bore holes will be lo gg during the drilling using the standard soil <br /> classification method. Soil samples will be transported mder a chain of custody to Sherwood Labs <br /> of Hilmar, Ca. for analysis or analyzed on site. Sampl s from Tank#2 will be analyzed per EPA <br /> Methods 8020 (BTEX), (MTBE), and 503018015(M) H-Gasoline. Samples from Tank#1 will <br /> anlyzed per EPA Method 8010& 8020. <br /> MONI'T'ORING WELL DEVELOPMENT <br /> After soil sampling is completed, the borehole on T #2 will be developed into two inch PVC <br /> cased monitoring well. Well depth, length of screened ell casing and sand filter,and the location <br /> of a bentonite plug will be determined in the field by a {PHS-EHD) representative and Foothill <br /> Engineering. Permits for the monitoring wells and reholes will be obtained by the drilling <br /> subcontractor from the (PHS-EH).Monitoring wells '11 be developed and purged before gauging <br /> and water sampling. <br /> MONITORING WELL TESTING <br /> The monitoring well will be gauged and water samples obtained and analyzed quarterly. A report <br /> summarizing the quarterly results of gauging and testing of each monitoring well will be prepared <br /> by the site owner's consultant. <br /> SUMMARY <br /> The work plan calls for Foothill Engineering to secure a services of a licenced drilling contractor <br /> to drill slant bore holes sampling on Tank#1. A vertical bore hole with sampling will be made on <br /> Tank#2. The Tank#2 bore hole will be used to instal a 2" PVC monitoring well. A report of the <br /> findings for both tank locations with soil sample analysis will be prepared by Foothill Engineering <br /> for review by all parties. <br /> Please address any questions,corrections or additions to Ery Rifenburg,Foothill Engineering,Phone <br /> 2091368-9381 <br /> Respectfully submitted, <br /> i <br /> Foo ngin <br /> Ery nbtu <br /> cc: Norman Higgins <br />
