of contamination is from the Exxon. Gasso site across the street. <br /> During the three months between the March & June measurements, <br /> the water table has risen almost 2. 5 feet, and slightly over 4 <br /> feet since last October. If residual contamination remaining an <br /> the soil was significant, and not locked up in the pore spaces, <br /> it should have been picked up by the water as it rose through the <br /> sediments. Those chemicals should have been detected in the <br /> downgradient well #2. A review of the above data shows that is <br /> not the case. Measured amounts of all tested components in that <br /> well were significantly lower in June compared to March. This <br /> indicates that any residual contamination remaining in the ground <br /> is not soluble, or only at very minor amounts, and should not <br /> impact the groundwater. <br /> In summary, the data recorded to date strongly indicates that the <br /> source of the contamination detected in the water beneath this <br /> property is from an off-site source, which appears to be located <br /> to the north and/or west. <br /> Water level measurements and sampling will be performed again in <br /> September, and a report prepared for the appropriate agencies. <br /> � If you wish additional information, please contact our office at <br /> j your convenience. <br /> Since <br /> 1 <br /> G� <br /> Wm. ter & Associates <br /> cc: ank Morita <br /> CVRWQCB, Beth Thayer �S�ER4GF�CO <br /> R11A&J.t3tFR <br /> NWO.860 <br /> OF CAU <br /> 5 <br />
