To date, this well receptor survey has not been rcceivcd <br /> by County or Regional Board staffs. Your on-site water supply well is impacted with gasoline and <br /> methyl tertiary butyl ether(MTBE), and may be acting as a conduit for shallow contamination to pollute <br /> the deeper groundwater aquifer(s). <br /> The high concentration of gasoline range petroleum hydrocarbons and MtBE, documented in <br /> groundwater at your site, threatens public health and beneficial uses of the groundwater resource. There <br /> are numerous domestic use water supply wells and surface water features in the vicinity of your site, <br /> which may facilitate human exposure to the contamination or more rapid contaminant migration. <br /> In accordance with Section 13267 of the California Water Code, you are directed to: <br /> 1_ Submit a plan and schedule to replace the water supply at the Speedy Mart with an alternate <br /> (potable) water supply by 26 May 2000, <br /> 2. Submit a complete sensitive receptor survey of all water supply wells and sensitive receptors <br /> located within 2,000 feet of your site boundaries by 26 June 2000. <br /> 3. Complete Quarterly Groundwater Monitoring and Sampling of the four on-site monitoring wells, <br /> and provide a report of quarterly groundwater monitoring and sampling activities and analytical <br /> results by 26 dune 2000. All wells must be sampled and analyzed for TPHg and BTEX by EPA <br /> Methods 8015/8021 or 8260B, and for all fuel oxygenates, ethanol, methanol, 1,2-DCA, and <br /> EDB by EPA Method 8260B. <br /> 4. Subunit a workplan to define the vertical and lateral extent of the contamination both on-site and <br /> off-site by 26 dune 2000, <br /> California Environmental Protection Agency <br /> 0 Recycled Paper <br />
