Page 5 <br /> Groundwater Monitoring Report <br /> Project No, 750.2 <br /> June 15, 2001 <br /> that biodegradation of the contaminants is at a rate <br /> sufficient enough to keep the <br /> E BTEX/TPH-G plurne in a small area around the source without depleting the oxygen to <br /> a level to slow the reaction process. <br /> Recommendations: <br /> a * Quarterly groundwater monitoring will continue at the site. The next event will occur <br /> by August 31, 2001. <br /> �. * A Vadose Zone Remediation - Corrective Action Plan has been approved by San <br /> Joaquin County PHS/EHD and cost pre-approval is being requested from the USTCFP. <br /> The application for Authority of Construct for the vapor extraction treatment system has <br /> been submitted to the SJVAPCD. We recommend that the vapor extraction system be <br /> operated for a few months to remove the high concentrations of leachable contaminants <br /> and then this site be closed. <br /> 3.0 LIMITATIONS <br /> This report was prepared in accordance with the accepted standards and practices of the <br /> field of environmental geology, groundwater hydrology and good business practices. It <br /> should be recognized that definition and evaluation of environmental conditions is a <br /> difficult and an inexact science. Judgments leading to conclusions and recommendations <br /> are generally made with an incomplete knowledge of the site-specific conditions present. <br /> The tasks proposed and completed during this project were reviewed and approved by the <br /> 1 local regulatory agency for compliance with the law.
