The monitoring holes at each site were spaced approximately 10 feet from one another. <br />The pilot hole site at each site was plugged and reclaimed in accordance with DRMS <br />regulations. (See Figure 1) After the hole was drilled to total depth, bentonite gel was <br />pumped down the drill pipe to the surface. Each pilot hole was subsequently plugged by <br />pouring two 50 pound bags of 3/8" bentonite chips down the hole. Drill cuttings were <br />shoveled into the hole to ten feet from the surface. The final ten feet was filled with <br />concrete and a survey cap marking the hole was set in the concrete at the surface. Holes <br />EP-08 and SWP-08 had left a two-foot gap from the surface to the top of the concrete that <br />was filled with native soil. Both of these locations have been used for agricultural <br />purposes and the landowners expressed their wishes not to have concrete to the surface. <br />At all sites, excess cuttings were raked out and all debris was removed. Each monitoring <br />well was capped with a protective 6" PVC casing set in the concrete about a foot and a <br />half above the surface. Each site was seeded by a manual broadcaster using a dry-land <br />pasture seed mix. <br />Map 1 shows the as-built monitoring sites. Figure 1 shows the method of plugging the <br />three pilot holes. Figure 2 shows completion diagrams for each monitoring well.
