The results of the survey were used by BC to locate <br /> boreholes for soil sampling. Due to a permitting technicality, the <br /> San Joaquin Local Health District has not accepted the survey. <br /> Therefore, the results are not included in this report. <br /> During May 1987, a prelrainary site investigation was conducted <br /> at the station by BC. The objectives of the investigation were to <br /> determine groundwater gradient, groundwater and/or pieziometric <br /> . levels, identify product in soil and or groundwater beneath the site, <br /> evaluate the site geology, identify any product in nearby wells, and <br /> obtain information necessary for evaluating potential remedial <br /> actions at ' the ' site. The work was conducted as described in EC's <br /> workplan (Appendix D) . This report p pp p presents the methods utilized in <br /> and the results of the preliminary site investigation. <br /> r <br /> I <br /> i <br /> f <br />
