The highest total xylene <br /> isomers concentration is 0.0024 ppm in well MW-3. In well MW-5, total xylene isomers <br /> were reported as 0.0008 ppm which is 0.0003 pilin above the detection limit for the <br /> constituent. With the exception of total xylene isomers in well MW-5, water samples <br /> from wells MW-5 and MW-7 indicate TPH as gasoline and BTEX constituents are <br /> f <br /> below the detection limits for the tests used in the two wells. <br /> 26 <br /> A, p/ieod GeoSystems - --- <br />
