THE <br /> SOUTHLAND <br /> CORPORATION <br /> March 15, 1991 <br /> San Joaquin County Department <br /> of Health Services <br /> C/o Ms. Laurie A. Cotulla <br /> P.O. Box 2009 n <br /> Stockton, CA 95201q ... � ? <br /> Re: Southland property #20680 MAR f 9 19ol <br /> SJCDOHS site Code #1886 ENVIRONMENTAL HEALTH <br /> 9110 Thornton Road PERMIT/SERVICE5 <br /> Stockton, Ca <br /> Dear Ms. Cotulla: <br /> I am enclosing to you for your review and file a report dated <br /> March 11, 1991 which details the operation of a vapor extrac- <br /> tion system which previously operated at the above referenced <br /> project site. <br /> In response to item number one (1) of your letter dated Feb- <br /> ruary 20, 1991, Southland trusts that the enclosed Vapor Ex- <br /> traction report will satisfy any immediate concern over the <br /> decommissioning of this equipment. <br /> In defense of our action in decommissioning the ground water <br /> treatment system, the following comments are made. Groundwa- <br /> ter samples collected from the recovery well indicate that <br /> drinking water standards were exceeded once during the past <br /> seventeen (17) months. This event occurred on January 25, <br /> 1990 when 1.0 parts per billion of benzene was detected in a <br /> laboratory sample. I cannot personally justify the expense <br /> of operating a remedial system(s) when there is no evidence <br /> that any contaminant exists above state action standards. <br /> A work plan which will be forthcoming to you in the next few <br /> days will include the installation of a single on site boring <br /> and monitoring well. The soil and groundwater results col- <br /> lected from this planned activity should indicate if any fur- <br /> ther remedial effort is necessary or if Southland should pro- <br /> ceed in discussions with your office as the specific <br /> requirements for obtaining case closure on this site. <br /> SOUTHLAND ENVIRONMENTAL SERVICES/ LOCATION 2987 <br /> 5820 STONERIDGE MALL ROAD/SUITE 310/P.O.
