All Pure's proposal is to clarify the conditions under which these wells may be abandonedin the <br /> future before signing an access agreement with BCID. <br /> I agree with All Pure's proposal to abandon these two wells in the BCID easement under the conditions <br /> stated after a minimum of four quarterly sampling events. These conditions are: <br /> 1) The volatile organic compounds carbon tetrachloride and chloroform,which have been found in <br /> wells at the All Pure site, are not detected at levels of concern in ground water collected from these <br /> two wells, <br /> 2) Chemicals that might be associated with the All Pure site are below health advisory concentrations in <br /> these wells, and the wells are not needed to characterize the edge of any ground water plume created <br /> by these chemical, or <br /> 3) The All Pure site has received approval for no further action from the Board. <br /> We expect All Pure to proceed with its negotiations with the BCID to obtain access for the offsite wells. <br /> Please continue to keep me informed, as you have done in the past, if there are any other delays in <br /> obtaining access for these wells. We expect a schedule for the offsite well installation and submittal of a <br /> ground water investigation report to be submitted after All Pure signs an agreement with BCID, as you <br /> have proposed. <br /> If you have any questions,you may call me at (916) 255-3048. <br /> POLLY LOWRY <br /> Associate Engineering Geologist <br /> PAL:pal/Isb <br /> cc: San Joaquin County Public Health Services, Stockton <br /> Mr. Tim Vickers, All Pure Chemical Company, Tracy <br /> Mr. Noel Lerner, Helmick &Lerner, Sacramento <br /> Recycled Paper Our mission is to preserve and enhance the quality of California's water resources,and <br /> ensure their proper allocation and efficient use for the benefit ofpresent and future generations. <br />
