(AGE)recommends monthly <br /> sampling of the domestic drinking water well located at 14749 Thornton Road(Three B's Truck Plaza),Lodi,California, <br /> for analysis of methyl tertiary butyl ether(MTBE). <br /> The State of California Department of Health Services has adopted a concentration of 13 µg!1 as an action level for <br /> MTBE in March 1999,and has adopted a concentration of 5µg11 as a secondary maximum contaminant level(MCL) <br /> in January 1999. <br /> The Three B's Truck Plaza domestic drinking water well was previously sampled in April of 1999. MTBE was not <br /> detected at the domestic drinking water well,however MTBE was detected at a nearby ground water observation well <br /> (MW-6) located less than 15 feet away at a concentration of 38 micrograms per liter(µg11). MTBE concentrations <br /> detected at MW-6 exceed the action levels of 13 µg/l and exceed the secondary MCLS of 5 µg11. Due to the close <br /> proximity of MTBF-impact, AGE recommends that a monthly monitoring program be developed for sampling the <br /> domestic drinking water well with respect to MTBE concentrations.Ground water samples will be logged on a chain-of- <br /> custody form, placed In a chilled container and transported to a California Department of Health Services (DHS)- <br /> certified laboratory for analysis of MTBE by EPA Methods 8260. <br /> if you have any questions or comments,please contact me at(209)467-1006. <br /> Sincerely. `y'��PH�NOf eOe <br /> a `1� � <br /> Advanced GeoEnviron mental,Inc. � 3 ` <br /> a3 CP <br /> 7 4 <br /> o.681 <br /> Timothy 7. elh Nuel C.Henderson,Jr. <br /> Project Geologist Senior Project Geologist <br /> California Registered Geologist No. 5837 <br /> cc; Mr.Andy Zarakam- Three B's Truck Plaza - <br /> 4005 North Wilson Way, Stockton,California 95205 <br /> Telephone(209)467-10% FAX(209)467-11.18 <br />
