�1,�Clayton <br /> GROl1P SERVICES <br /> The groundwater samples did not contain TPH-gas, BTEX, and MTBE above analytical <br /> ' detection limits Low levels of diesel were detected in groundwater from each of the <br /> three groundwater monitoring wells at concentrations ranging from 64 µg/L to 530 µg/L <br /> These diesel-range hydrocarbons are within the range detected by analysis of first quarter <br /> 2003 samples Based on the limited diesel fuel impact in the purge water, we recommend <br /> that it be discharged to the local Publically Owned Treatment Works (POTW) through <br /> the onsite treatment system after approval by the PHD/EHD Groundwater flow direction <br />' and gradient are consistent with first quarter 2003 results <br /> The next groundwater monitoring event will be conducted as per the requirements of the <br />' PHD/EHD in the third quarter of 2003 <br /> 1 I <br /> 1 <br />' <br /> 3 <br /> S\Proj\P02263\Q2 Rpt doc <br />
