During volatile hydrocarbon analysis of an existing monitoring well (MW2), an unknown peak <br /> was identified between benzene and toluene. Additional analysis detected halogenated volatile organic <br /> compounds. These results have been subsequently confirmed during sampling on April 8, 1993. <br /> An onsite non-community public water system well, which supplies water to several businesses, was also <br /> tested on April 8th and significant levels of halogenated volatile organic compounds were detected. Follow <br /> up testing of this well on May 5, 1993, again showed significant contamination. <br /> Copies of the analytical results on the public water well are enclosed for your reference, along with a site <br /> map showing the location of the former UST and well locations. Also included are excerpts from the <br /> consultant's report regarding their findings and the initial MW2 analytical results. As noted in the <br /> consultant's report, the source of this contamination has not been clearly identified nor has the possible <br /> extent. There are private domestic wells in the immediate vicinity. <br /> Please notify us as soon as possible of the action your agency will take on this matter. Our office has <br /> instructed the purveyor (who is also the property owner) to provide bottled water to his tenant businesses. <br /> If you have any questions, please contact me at (209) 468-3431. <br /> Jogi Khanna, M.D:, M.P.H. <br /> Health Officer.' <br /> Laurie A.
