GeotogicaC?ecfmics Inc. • • Page 2 George's Service Project No.: 425.2 April 10, 1998 Copies of the Work Plan, PHSEHD correspondence, bids and an itemized budget spread sheet of costs for performing this work are enclosed for your review. In planning for this next work we have developed: • a summary of the work completed to date, • a proposed direction of the project from this point, • a proposed mechanism for bidding work for the USTCFP, • a tentative schedule for implementing the work. Summary of Work to Date On January 25, 1995, Del-Tech and GTI prepared a work plan for the preliminary soil and groundwater investigation. On February 17, 1995 PHSEHD made comments and requested modification to work plan which was submitted in an addendum to the work plan on February 23, 1995. The plan and addendum were approved with additional comments. On April 25, 1995, GTI, Del-Tech, and V&W installed 3 groundwater monitoring wells, 2 drilled boreholes, and 6 hand auger soil borings in an attempt to evaluate the lateral extent of soil and groundwater impacted by the release of gasoline on this property. The wells were monitored on May 4, 1995 and soil and groundwater samples were tested for TPH-G and BTEX compounds. On August 11, 1995, GTI prepared a report of the geologic activities of this investigation and Del-Tech prepared a summary report including the chemical testing results. Mary Meays of PHSEHD called on August 29, 1995 with comments on the report and requested that GTI provide conclusions and recommendations. This was immediately prepared and submitted for review. Copies of the report and addendum are attached. On November 9, 1995, PHSEHD requested additional soil and groundwater investigation be performed and that a work plan be submitted proposing the work to be performed. On January 29, 1996 GTI prepared a work plan for additional site characterization and on February 23, 1996 PHSEHD approved the plan with comments and modifications. Before the additional borehole and wells would be drilled, the site would undergo additional groundwater monitoring establish a trend in groundwater gradient. On January 20, 1997 GTI prepared an addendum to the January 29, 1996 work plan. On February 3, 1997 Mary Meays approved the plan with comments. Five additional water table groundwater monitoring wells and one deeper monitoring well were installed on April 29 & 30, 1997. GTI prepared a report Soil and Groundwater Investigation, August 5, 1997, summarizing this work and the data obtained. Proposed Direction of Proiect The additional site characterization work plan details the work outlined below. As this work is being performed and information is being obtained, we will evaluate it to determine if modifications should be made to streamline the investigative process and bring cost savings to the client and the Fund.
