However, no soil <br /> contamination was documented or visually observed during the <br /> 19 April 1990 underground storage tank removal. <br /> The CVRWQCB Agricultural Regulatory Unit determined that the <br /> "pesticide contamination at the site has been reduced to <br /> levels which will not pose a threat to other surface or <br /> groundwaters" and referred the underground storage tank issue <br /> to the CVRWQCB Tank Unit, which in turn referred the case to <br /> PHS/EHD on 20 October 1992. <br /> The presence of toluene-was detected during the construction <br /> of the monitoring wells throughout the site between the depths <br /> of 10 - 15 feet below grade (fgb) . Toluene is a common <br /> constituent of many compounds used in industrial applications. <br /> This presence of toluene was not interrupted by the CVRWQCB <br /> Agricultural Unit as being a significant threat to water <br /> quality. <br /> A Mision of San Joaquin County Health Care Services <br />
