During the course of a Site <br /> visit on April of 2000 conducted by San Joaquin County Environrnemal Health Division <br /> (S)CEHD), it was discovered that four dry wells in the evaporation pond were not permitted. <br /> The possibility exists that an unknown substance may have impacted the storm water holding <br /> pond located on the southeastern portion of the subject Property. Based upon this information. <br /> AMES recommends the following. <br /> PROPOSED SCOPE OF WORK <br /> In order to achieve the objectives of this investigation, AMES proposes to perform the following <br /> tasks as part of the Limited Phase H investigation in the area of the storm water holding pond: <br /> • AMES will lower one(1) spoon sampler (3'h")within the four inch french pipe of each of <br /> due four drywells. The boring will be advanced to a maximum depth of 6-8 inches from the <br /> bottom surface. The laboratory will then be instructed to remove their sample extraction <br /> from the bottom portion of the sampling tube. If water is encountered in it drywell,the water <br /> will be removed using a bailer before the sample is collected. <br /> • The soil sample will be collected using a butterfly vale spoon sampler driven in advance of a <br /> 10-pound hand-operated hammer. AMES staff will renmve the tube from the sampler for <br /> analysis. The ends of the soil-filled sample tube will be sealed with Teflon-lined caps and <br /> duct taped The soil sample will be labeled then stored in a chest cooled with ice and <br /> transported to a sorts certified analytical laboratory for analysis under chain-ofoustody. <br /> • A state-certified laboratory will be used to perform chemical analyses on the soil sample <br /> collected. The sample will be analyzed for total petroleum hydrocarbons (TPH) for <br /> 1 art <br /> ASSET MANAGEMENT A ENVIRONMENTAL SERVICES <br /> 62 Avignon Avenue • Foothitl Ranch, CA 92610 • (949) 586-3570 • Fax (949) 586-7315 <br /> e-mail. amesi(Pearthlink.net •web page, hop:/Jwww.earthlink.neV—amast <br />
