South Basin Groundwater Protection Project

The South Basin Groundwater Protection Project (SBGPP) focuses on a two-square-mile portion of the groundwater aquifer located under Irvine, Santa Ana, and Tustin.

Chemicals left behind from decades-old manufacturing have contaminated the shallow groundwater. A water supply well has been removed from service because contaminants reached elevated levels.

OCWD is working closely with the California Department of Toxic Substances Control and Regional Water Quality Control Board to map the occurrence of the contaminants, select a remedy, and implement groundwater cleanup.
