EHD required <br /> you to assess the dwelling and septic systems. Samples of the contents of the <br /> septic tanks were obtained and analyzed. The analytical results showed that <br /> disposal of chemicals (toluene, ethyl benzene, xylene, trichlorotrifluoroethane <br /> and 1,4-dichlorobenzene) into the septic system had occurred. San Joaquin <br /> County Ordinance Code Section 9-1110.7 prohibits disposal of solvents and <br /> toxics in a septic system. k <br /> EHD has implemented a Local Agency Groundwater Protection/Underground <br /> Injection Control (UIC) Program in accordance with guidelines prepared by the <br /> United States Environmental Protection Agency (USEPA). The primary focus of <br /> the program is to protect drinking water by identification and evaluation of <br /> subsurface disposal of prohibited substances. The presence of toluene, ethyl <br /> benzene, xylene, trichlorotrifluoroethane and 1,4 dichlorobenzene in your septic <br /> tanks makes it subject to the underground injection control regulations and our <br /> local program. 3 <br /> i <br /> Further investigation to determine whether the chemicals found in the septic <br /> tanks flowed into the soil from the leach lines and/o : seepage pits of the septic <br /> system must be performed to evaluate if there is a threat to drinking water. If <br /> chemicals have been released to the subsurface from the leach lines and/or <br /> seepage pits continued use of the septic system may cause further percolation of <br /> the chemicals, increasing the threat of chemical contamination of the <br /> .groundwater. <br /> The above referenced property has been placed onl-the EHD list of UIC sites and <br /> will remain an open case until the proper investigation has been conducted. <br /> Activities involving site assessment require a professional level of expertise. <br /> Work and reports related to closure of this case must be signed by a California <br /> registered geologist (R.G.) or professional engineer (P.E.). <br /> l i <br />
