Delhi Groundwater

The Delhi Groundwater also named the South Basin Groundwater by Orange County Water District (OCWD), is a two-square-mile portion of the groundwater aquifer located under Irvine, Santa Ana and Tustin. This groundwater is contaminated near the surface with volatile organic compounds (VOCs) left behind from decades-old manufacturing. A community outreach meeting was held on March 29, 2023 to provide a status update on the clean-up and saftey of Santa Ana's drinking water.
