III. Monitoring Well Inspections, Repairs and Redevelopment <br />Subsequent field reconnaissance and magnetometer survey were <br />conducted on April 25, 2003 in order to pin point and confirm the actual location <br />of MW-1 and 4. The four monitoring wells were repaired and redeveloped on <br />April 25, 2003. Blaine Tech Services performed the work under the supervision <br />of Chris Palmer, R.G., CEG, CHG, retained by TRE Consulting. The following <br />repairs and redevelopment was performed as discussed below (see Appendix A <br />for Blaine Tech field sheets and Table 2). Photographs of all four monitoring <br />wells as well as the repair and redevelopment activities are also presented in this <br />report. <br />111.1. Monitoring Well MW-1: <br />The initial location of monitoring well MW-1 was thought to be at a metal <br />surface mount with an open casing. Upon clearing this metal mount, the metal <br />was apparently a fence post holder, so additional magnetometer sweeps were <br />performed in the immediate vicinity. MW-1 was located a few feet away from the <br />initial position, with the well box partially intact. The well casing expansion plug <br />was in place. The casing had not been filled with soil as initially thought. Blaine <br />Tech proceeded to surge and redevelop the well. The well was a 4-inch <br />diameter casing about 22 feet deep. Blaine Tech surged the casing for about 10 <br />minutes and then removed about 63 gallons of water with a submersible pump. <br />Sand pumping was minimal. The water was turbid initially but continued to clear <br />during the pumping. The well pumped down about 5.4 feet and the water level <br />was rising upon ending redevelopment. <br />A new surface mount (see photograph 1 below) and well box was installed <br />around the MW-1 casing. The box was cemented in position with a new locking <br />expansion cap <br />Photograph 1- A Refinished view of MW-1 with New Well Cover, Cap, and Lock <br />5
