Hwy. 132 <br /> Vernalis CA 95385 <br /> San Joaquin County Public Health Services, Environmental Health Division (PHS/EHD) <br /> has reviewed the "Quarterly Report— February 2000", dated April 26, 2000, that was <br /> submitted by Advanced GeoEnvironmental, Inc. (AGE) on behalf of the above <br /> referenced site and has the following comments. <br /> The report documents the installation of five on-site groundwater-monitoring wells and <br /> one soil boring which took place on February 8-9, 2000, and the subsequent <br /> development and sampling of the wells which took place on February 28, 2000. <br /> Results from analysis of the collected soil samples indicate one area of significant <br /> contaminant impact. The former dispenser island area had methyl tertiary butyl ether <br /> (MtBE) to a maximum depth of 25-feet below surface grade (bsg), and a maximum level <br /> of 2,700 parts per billion. Results from the water samples analyses were non-detect for <br /> all petroleum hydrocarbon constituents tested for. The report recommends that another <br /> monitoring event be performed, and that a well receptor survey be conducted. <br /> A second groundwater-monitoring event was conducted in June 2000. Quarterly <br /> groundwater monitoring should continue at this site until further direction from PHSIEHD. <br /> In correspondence dated June 16, 1999 PHSIEHD requested that a well survey be <br /> conducted to identify the locations of all agricultural, industrial, domestic, municipal and <br /> other wells within a 2000-foot radius of the site. Please proceed with submittal of the <br /> survey.
