The California Division of Drinking Water (DDW) recently lowered the Response Levels (RL) for PFOA and PFOS on February 6, 2020. The new RL for PFOA has been set to 10 parts per trillion and 40 parts per trillion for PFOS. As a result of the lower RL, we have taken one of our wells out of service in order to continue serving safe, clean drinking water to our residents we have taken one of our wells out of service. All water being served continues to meet or exceed all state and federal standards.
The Orange County Water District (OCWD) is responsible for managing groundwater in the Orange County area. OCWD contracted with Carollo Engineers to prepare individual Planning Study reports for ten impacted Orange County water agencies. The Planning Study evaluated several alternatives to reducing PFOA and PFOS levels in the groundwater including blending with import water, blending with other sources and engineered treatment. Carollo Engineers has met with individual agencies to determine the best alternatives for their unique circumstances and a final report is expected to be complete in June 2020.
The newly-released film “Dark Waters” has drawn attention to the effects of PFAS in water. The plot centers on a corporate defense attorney taking on a lawsuit against DuPont to fight PFAS and their effect in the environment. It focuses on contaminated drinking water caused by manufacturing plants leaking chemical waste, specifically PFOA, into the environment.
The movie highlights very high levels of PFOA in water supplies as a result of direct pollution by manufacturers into the local environment. In Orange County, very low levels of PFOA and PFOS have been detected in the groundwater basin. The levels are in no way comparable to those featured in “Dark Waters.” The City of Fullerton is partnering with Orange County Water District, along with the other producers in the basin affected by PFAS to ensure we continue to provide safe, high quality drinking water. This is our top priority.
