OCWD’s pilot program for PFAS treatment options continues to move forward. It’s anticipated both the lab- and pilot-scale testing will be conducted in parallel, with the pilot testing likely to begin later in October and the bench/lab testing in late October or November. For the pilot, building and pilot skid preparation are underway. Piloting will be conducted at an OCWD-owned well near Warner Basin in Anaheim. OCWD’s consultant, Jacobs, has completed a draft test plan for the lab-scale Rapid Small-Scale Column Testing (RSSCT). The lab testing will evaluate the same GAC and novel products as the pilot and will run on OCWD’s pilot test well water supply and on 10 individual retailers well water sources. Jacobs has recommendations for which well and/or blend is to be used from each of the participating water retailers. Once this planning is finalized, OCWD will ensure concurrence of the well/blend choices with each retail agency, as well as coordinate the sampling and delivery of required volumes of water.
OCWD reviewed submissions received from its Request for Proposals for a PFAS Treatment Systems Planning Study. Staff will bring a recommendation to the October 9 Water Issues Committee meeting. The Water Issues Committee will also be continuing discussions about a potential program to assist OCWD’s water retailers with treating groundwater supplies to remove PFAS.
OCWD continues to engage with legislators, regulators and elected officials on this important issue. On September 24, representatives from OCWD, Santa Clarita Valley Water and Intertox met with staff from CalEPA, the State Board, DDW, and California Office of Environmental Health Hazard Assessment (OEHHA) to ask technical questions about the OEHHA report and findings that DDW used to recently lower drinking water Notification Levels and will likely use when lowering Response Levels later this year.
OCWD also continues to work with other stakeholders throughout the state to share information and updates on PFAS issues. Upcoming presentations include:
San Bernardino Valley MWD Advisory Commission on October 10
ACWA PFAS Regulatory Summit on October 17
SAWPA EC Task Force on October 22
