(CASE NO. 3032) <br /> P r -hr-/ <br /> We have reviewed the Exceedances of Water Quality Protection Standards and Maximum <br /> Contaminant Levels, Fourth Quarter 2003 Monitoring Period submitted on 13 February 2004 by <br /> GeoLogic Associates on behalf of Allied Waste Industries, Inc. The report provides results of retest <br /> samples from MW-4 (toluene,benzene, ethylbenzene, MTBE and xylenes), MW-9B, and MW-l0A <br /> (barium and beryllium). Barium and beryllium were detected during the 5-year constituent of concern <br /> testing. The VOC detections in MW-4 and the elevated beryllium in MW-9b and-1Oa were not <br /> confirmed. However,barium concentrations greater that the state MCL were confirmed at MW-9A. <br /> Barium should be added to the list of quarterly groundwater monitoring constituents for each well in <br /> the French Camp monitoring system. Because barium has not previously been systematically sampled <br /> at this site,there is insufficient background data to determine if this represents a release from the <br /> landfill. <br /> Regional Board staff anticipates revising the facility WDRs in the Fall of 2004 when the landfill is <br /> closed. Until the WDRs are revised Forward Inc. should include barium in the list of groundwater <br /> monitoring constituents. <br /> If you have any questions please call me at (916) 464-4614. <br /> - <br /> Ross D.
