Kaweah Subbasin Groundwater Monitoring Well Installation Project

NOE - Notice of Exemption
Document Description
In 2014, the Sustainable Groundwater Management Act (SGMA) was signed into law, requiring local Groundwater Sustainability Agencies (GSAs) to manage groundwater in their service area. This necessitated the development of an adequate network of appropriately spaced groundwater monitoring wells. With secured funding, DWR has established the Technical Support Services (TSS) program to help GSAs meet their SGMA requirements by providing services to install groundwater monitoring wells, conduct downhole video logging, and give training on methods to accurately monitor groundwater levels. The Kaweah Technical Support Services (TSS) Well Installation Project consists of installing four separate nested groundwater monitoring wells at four locations. All well sites will be marked by Underground Service Alert, then hand tools will be used to excavate to a minimum depth of 5 feet. Next, a truck mounted drill rig will drill a pilot hole in the excavation while a mud cleaner is used to filter out solids and return the drilling mud to the drill bit. When the pilot hole is at the desired depth, the bore hole will be expanded to a diameter of approximately 14 inches. Each well cluster will consist of two or three PVC casings, and the base of each well, from the bottom up, will consist of sand, a filter pack, and a bentonite seal. Cement will be pumped from the support truck to form a sanitary seal in accordance with state and county requirements. A raised well monument and concrete pad that is approximately four square feet and four inches tall, with four approximately 4-foot high metal crash posts will be installed at ground level to protect the well from potential damage; alternatively, the well can be installed in a flush-mounted vault in accordance with Tulare County road ordinances.
