. `..0) Mr. Michael Infurna December 17, 1993 Page 3 Proposed Work In order to fulfill the requirement of the County's letter, the client proposes to perform the following work at the site. ESE agrees with the County that until ground water gradient is , determined at the site that no additional ground water monitoring well locations can be proposed. Therefore, the initial emphasis of the work to be performed is to determine the site ground water flow direction and gradient and determine if the water supply wells at the site influence the gradient and receive water from the upper portion of the aquifer. • Interim remediation, or source control,will be re-initiated at the site. This corrective action task is in compliance with Section 2722 of Article 11, Title 23. the work will be performed by the site owners as a cost saving measure. ESE will report the progress of the interim remediation in quarterly monitoring reports. The interim remediation work to be performed is as follows: Mr. Robert Cecchini will perform at a minimum bi-weekly (twice a month), evacuation of water from Well UST-1 for a an indefinite period of time until a full scale remediation system is required. He will perform the following tasks: • Measure water and product levels in the well using an electric water level sounder and a clear bailer. This information will be recorded. • Evacuate 30 to 50 gallons of water from well UST-1 using an electric submersible pump. If the well should become dry during the purging process, then we will evacuate the well dry a total of three times. The volume of water pumped from the well will be recorded. • The water evacuated from the well will be stored in DOT rated drums in a secure area of the site. • Dispose of all water stored in drums by hauling to a local recycler. • Results of the ground water recovery will be documented in the quarterly monitoring reports to be prepared by ESE. • In order to gain an understanding of the relationship of the water supply wells at the site to the local gradient ESE recommends utilizing a downhole camera to determine the screened interval in the water supply wells at.the site. The purpose of this effort is to determine if these wells are screened in the same interval as the monitoring wells can be utilized for monitoring ground water gradient and possibly water quality. Determination of how these pumping wells affects.the site ground water gradient is necessary before any additional ground water monitoring wells are placed at the site.
