(AGE) for the above referenced site. <br /> In a letter dated June 6, 2002, EHD agreed with the AGE recommendation for a <br /> deep soil boring in the former UST area with collection of water samples to�deflne <br /> the vertical extent of the hydrocarbon impact to ground water. This <br /> recommendation was proposed again in the Fourth Quarter 2002 report. EHD <br /> agreed with the recommendation of a boring because it would allow for collection <br /> of ground water samples from more than one permeable zone if determined <br /> necessary. <br /> The Site Assessment Work Plan, however, proposes to install a depth-discrete <br /> ground water monitoring well (screen interval from 45 to 50 feet below surface <br /> grade): The boring logs from previous investigations at the site show fine- <br /> grained material to a depth of 26 feet and sand from 26 to 30 feet below surface <br /> grade (bsg). None of the investigations at this site have been beyond 30 feet <br /> bsg, so the lithology beneath this depth is unknown at this site. The monitoring <br /> well screen interval must be placed in a zone of permeable material. The work <br /> plan must reflect this, not propose placement of the well screen at an arbitrary <br /> depth of unknown lithology. <br /> The September 2002 Site Assessment Work Plan is not approved. Please <br /> submit a work plan for a deep soil boring as proposed in quarterly reports or <br /> construction of a monitoring well that will be based on site lithology beneath 30 <br /> feet and will be screened in the next permeable zone by February 5, 2003. <br /> 1 <br />
