In the past , water samples from MW1 and MW6 were tested using EPA <br /> method 8240 and were below detection limits for these compounds, <br /> see Update Status Report 21, September, 1993 Water samples <br /> obtained on March 4 , 1994 from MW1, MW6, MW9 and MW11 were tested <br /> using EPA Method 8010 and were below detection limits for these <br /> compounds Water and vapor samples obtained from MW1, MW6 and <br /> MW9 on April 19, 1995, were tested using EPA Metod 8260 . All <br /> priority compounds were below detection limits . <br /> WEGE changed the BACT from Thermal Oxidation (REMOX unit) to <br /> vapor phase Carbon Adsorption on March 6, 1996 This <br /> modification to the BACT was approved by San Joaquin Valley <br /> Unified Air Pollution Control District on May 3 , 1995 . Currently <br /> WEGE is conducting the weekly emission screening of the carbon <br /> units and LTT is continuing the weekly venting of MW8 <br /> TIME FRAME <br /> July, 1996 MW8 venting, ground water gauging <br /> and vapor extraction system air <br /> monitoring <br /> August, 1996 MW8 venting, ground water gauging <br /> and vapor extraction system air <br /> monitoring <br /> September, 1996 Quarterly Ground Water Sampling <br /> (select wells; MW1, MW2 , MW3 , MW8, <br /> MW10 and MW12) MW8 venting, <br /> ground water gauging and vapor <br /> extraction system air monitoring <br /> HEALTH AND SAFETY <br /> This site is being treated as a class D site, normal common sense <br /> be used <br /> LIMITATIONS <br /> Ine conclusion and recommendations presented in this report are <br /> based upon the following <br /> A The exploratory test borings drilled at the site . <br /> B The Bouwer and Rice Slug test . <br /> U.
