Health Protection Zone Water Sampling

When drilling or reworking oil and gas wells, Senate Bill 1137 (Gonzales, 2022) requires oil and gas operators to offer groundwater and surface water sampling in areas within 3,200 feet of the wellhead if it is located in a Health Protection Zone (HPZ). A HPZ is an area within 3,200 feet of a sensitive receptor. Sensitive receptors can include residences, schools, health care facilities, community centers, and other public buildings.

The California Geologic Energy Management Division, California Air Resources Board, and State Water Resources Control Board are called to collaborate in the implementation and enforcement of HPZs by the 2026 Memorandum of Understanding to protect public health, safety, and water of beneficial use
