Wilson Way <br /> Stockton, CA. 95205 <br /> During monitoring well installations at U-Haul on March 17, 2003, San Joaquin <br /> County Environmental Health Department (EHD) discovered a public water <br /> system (well) at Frontier Motel, located adjacent to the U-Haul site. EHD advised <br /> the U-Haul consultant, Blaes Environmental Management (BEM), to gain access <br /> to the well and sample the groundwater for petroleum constituents associated <br /> with the leaking underground storage tank investigation. <br /> On April 14, 2003, BEM advised EHD that 1,2-dichloroethane (DCA) was <br /> detected in the groundwater sample from the Frontier well. A confirmation <br /> sample collected on April 15, 2003 confirmed the presence of DCA above the <br /> maximum contaminant level (MCL) for drinking water wells and Frontier Motel <br /> was advised that the well was impacted and should not be used. <br /> Frontier Motel management posted notification notices in each room and BEM, <br /> on behalf of U-Haul, provided potable water tanks and a pump to Frontier Motel <br /> as a temporary solution until a permanent potable water supply could be <br /> provided. <br /> U-Haul has been in contact with California Water Service, the public water <br /> supplier for the area, and connection to this public water supply for Frontier Motel <br /> is being investigated. <br /> DCA has been detected in groundwater samples from monitoring wells located at <br /> Harry's Auto Mart and U-Haul and both sites are suspect in contributing to the <br /> impact to the Frontier Motel well. EHD will continue to communicate with all <br /> parties and ensure that Frontier Motel has a water supply that meets drinking <br /> water standards. In addition, EHD will ensure each site investigates and <br /> mitigates the petroleum impact to the groundwater. <br />
