El DORADO STREET,STOCKTON,SAN JOAQUIN COUNTY <br /> 1 have reviewed the first quarter groundwater monitoring report for 1998 for your property at 222 <br /> North El Dorado Street in Stockton. My comments on the report are presented below. <br /> 1. Your laboratory uses reporting limits for volatile organic compounds (VOCs)which vary <br /> between 5 and 10 ppb. These limits are too high and should not be greater than 0.2 µg/1 as <br /> specified in your Monitoring and Reporting Program (MRP) No. 98-800. <br /> 2. The monitoring data should be tabulated in the same format as the attached sheet so that <br /> concentration trends are easily discernible. Reporting limits should be shown instead of <br /> "ND". To clarify if testing for halogenated VOCs has been performed for a monitoring <br /> period, the table should show that halogenated VOCs are less than the reporting limits. For <br /> example, for October 1996, only aromatic VOCs are shown on Table 1. Therefore, it is not <br /> clear if halogenated VOCs were tested during this sampling event. Any detected halogenated <br /> VOCs should continue to be reported as before. <br /> During a phone conversation in February 1998, Mr. Santochi, your consultant, requested <br /> eliminating dissolved metals and semi-VOCs. As specified in MRP No. 98-800, if the presence of <br /> dissolved metals and semi-VOCs is not confirmed, no further testing is required for those <br /> constituents. Therefore, Mr. Santochi's request is hereby granted. <br /> Please respond to these comments in your next quarterly monitoring-report which is due by <br /> 30 April 1998.
