November 22, 1988 THE <br /> SOUTHLAND Y <br /> CORPORATION <br /> San Joaquin County Dept. of Env. Health - I <br /> c/o Ms. Diane Hinson C' <br /> 1ty <br /> P.O. Box 2009 � 5 <br /> Stockton, Ca 95201 <br /> Re: 7-Eleven Property ##20680 <br /> 49'TO--Thornton Road <br /> - P Stockton, Ca <br /> Dear Ms. Hinson: <br /> I am enclosing the latest project activity summary for the <br /> above mentioned location. Since the report was published <br /> Southland has directed Groundwater Technology to provide <br /> a work plan which will include installation gf addit ' <br /> round water m torin wells. Southland has already authorized <br /> t e installation of an ORS Catalytic Scavenger. When installed, <br /> vapor extraction capabilities at the site will be increased <br /> from the current level of 100 CFM to 300 CFM and a number of <br /> additional extraction points will be connected. GTI is <br /> currently attempting to permit the unit with the appropriate <br /> local agencies. Any assistance on your part which might make <br /> installation of this equipment become a reality would be <br /> appreciated. Our goal is to have the unit in and operating <br /> by mid December. <br /> As to the additional work plan, we will provide it to you and <br /> the Regional Water Quality Control Board as soon as it is received <br /> by our office. <br /> On July 21, 1988 I sent a letter to you (copy enclosed) requesting <br /> a reduced domestic well sampling frequency and that two (2) <br /> of the domestic wells not be sampled further. I requested that <br /> Southland discontinue providing bottled water service to five <br /> (5) area residences. To date, I have not received a response <br /> from you. I would appreciate a phone call or note as soon as <br /> it is convenient. <br /> I have an additional request in the sampling frequency of our <br /> ground water monitoring wells (non-domestic) . The current <br /> sampling frequency is every two weeks ; I request that visual <br /> observations and water level measurements continue to occur every <br /> two weeks. I request that samples be collected for laboratory <br /> analysis every two months. The air stripper influent effluent <br /> would continue to be sampled every two weeks as required by our <br /> City of Stockton discharge permit. <br /> SOUTHLAND ENVIRONMENTAL SERVICES/ LOCATION 2987 <br /> 5820 STONERIDGE MALL ROAD /SUITE 310/P.O.
