PVC blank will be installed to a few inches from the ground surface and the top will be closed with a PVC cap. The well will be backfilled with 10-20 filter pack sand around and 2 feet below and above the screen. Above the filter pack to 3 feet from the ground surface the annulus between the blank PVC and open drill hole wall will be backfilled with bentonite. In dry portions of the hole, bentonite shall be hydrated at least at every 5 vertical feet of depth by adding about 5 gallons of water per 50 pound bag of bentonite or as recommended by bentonite supplier. The top of the observation well shall be protected in an 1-foot-diameter steel DOT approved man-hole set flush with the asphalt road surface. Concrete shall be used to backfill and secure the man-hole from the bottom the asphalt surface to 3 feet of depth. Cold patch asphalt shall be used to backfill the gap between the man-hole and asphalt road. Within the man-hole, the annulus from ground surface to 1 foot of depth will be left open.

c. Drill hole DH-15-2 shall be constructed as detailed above, except 1.5-inch-diameter PVC schedule 40, square-threaded well materials shall be used.
