Our updated research in 2022 found more than 120,000 such wells across 30 states. California could receive hundreds of millions of dollars to plug the 5,063 currently documented orphan wells in the state.
As many as two million water wells tap California's groundwater, with approximately 7,000 to 15,000 new wells constructed each year. They range from hand-dug, shallow wells to carefully designed large -production wells drilled to great depths.
The Department of Water Resources (DWR) has established well construction standards (well standards). Domestic wells must be drilled by a licensed well contractor and must meet applicable local and/or state well standards.
This year, nearly 1,400 household wells have been reported dry — a nearly 40% increase over the same period last year, and the highest annual number reported since 2013, when the California Department of Water Resources launched the Dry Well Reporting System.

Twenty seven platforms lie along the Southern California coast from Huntington Beach to Point Conception in Santa Barbara County. Twenty-three offshore drilling and production platforms are in federal waters at depths that range from 100 to 1,200 feet.
