Division of Drinking Water (DDW) recently lowered the Response Levels (RL) for PFOA and PFOS. The new RL for PFOA has been set at 10 parts per trillion and 40 parts per trillion for PFOS. As a result of the lower RL, data collected from fourth quarter monitoring and 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 meets or exceed all state and federal standards.
OCWD’s PFAS Planning Study is well underway and slated to conclude in May. District staff and Carollo Engineers met with each of the 10 impacted water agencies and presented a project update this week to OCWD and its member agencies, providing an overview of the various alternatives and analysis of options for getting wells back online, including relying on imported water to blend, blending with groundwater and engineered treatment. In the coming weeks, Carollo will meet again with individual agencies to determine the best alternatives for their unique circumstances.
The newly-released film “Dark Waters” has brought 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.
