The Q2-2002 Report included a <br /> summary of findings from drilling three soil borings,converting the borings to water table monitoring wells, and <br /> completing the second quarter groundwater monitoring and sampling event. <br /> The three soil borings were completed in early June,and the results of soil sampling showed gasoline and BTEX <br /> constituents at approximately 15 to 30 feet. First water was encountered at approximately 30 feet,and the depth <br /> to water following well development was approximately 26 feet. The calculated groundwater flow direction was <br /> reportedly to the southeast. The wells were purged and sampled on 13 June 2002, and the following constituents <br /> were identified in groundwater: <br /> • TPH-gasoline at<50 to 2000 micrograms per liter(µg/1); <br /> • Benzene at 1.1 to 92 µg/1; <br /> • MtBE at<0.5 to 2.6 µg/1; and <br /> • 1,2-dichloroethane at 1.2 to 40 µg/l. <br /> Upgradient also completed a cursory well receptor survey, and stated that approximately 100 residences with <br /> wells are located within 2,000 feet of the site. Documentation of well locations and well construction <br /> information was not provided. The nearest water supply well is an abandoned domestic well at the subject site. <br /> Reportedly,this well has been out of use since J&L Market connected to city supplied water more than two <br /> years ago. In our 23 January 2002 letter,Board staff requested J&L Market to purge and sample the on-site <br /> domestic well, and submit results in the second quarter monitoring report. Upgradient stated in the Q2-2002 <br /> Report that an attempt to sample the on-site domestic well was made;however,the pump could not be removed <br /> without special equipment,and the task was deferred. <br /> Upgradient concluded that the extent of soil and groundwater contamination has not been defined,and <br /> recommends drilling eleven additional soil borings to define the extent of contamination. Five of the borings <br /> will be converted into monitoring wells completed in the water table aquifer. Upgradient also recommends <br /> destroying the on-site domestic well in accordance with San Joaquin County Environmental Health Department <br /> (County)regulations. <br /> California Environmental Protection Agency <br /> VoRecycled Paper <br /> The energy challenge facing California is real.
