Document Description
The Tule Subbasin Well Installation project consists of installing nested groundwater monitoring wells at two locations. Each well site will be marked by Underground Service Alert, then hand tools will be used to excavate a minimum depth of 5 feet. A driller will use a truck-mounted drill rig to drill a pilot hole while using a mud cleaner to filter out solids and return drilling mud to the drill bit. The pilot hole desired depths below ground surface are 1,200 feet for Pixley ID and 1,550 feet for LTRID. Based on logging results, the driller will expand the borehole to selected depths to a diameter large enough to accommodate nested well casings (approximately 14 inches). Within each borehole PVC casings, sand, and a bentonite seal will be constructed. For a final sanitary seal, neat cement will be pumped from the support truck to fill the annular space between the casings and the borehole wall to a depth required by the local well permitting process. A raised steel well protective cover and concrete pad, approximately four feet by four feet in area and four inches tall with four approximately 3-foot high metal crash posts will be installed at ground level to protect the well from potential damage. See NOE for Full Details.
