Given the new Response Levels for PFOA and PFOS, retail water agencies throughout Orange County have voluntarily taken drinking water wells out of service.
Not having all of our local water supplies available this year will temporarily result in increased reliance on costlier water supplies imported from Northern California and the Colorado River. Long-term, water agencies in Orange County are planning on constructing and operating new treatment systems that will remove PFAS from drinking water wells.
To read OCWD’s response to the state’s recent action, please see the District’s
OCWD’s pilot program to test methods for removing PFAS from water is well underway. The pilot has been operating for approaching three months and to date, all results have been non-detect. The first Rapid Small Scale Column Tests (RSSCT) have been completed using water from the pilot test well and we have begun individual RSSCT assessments of impacted water retailer wells. Still to be loaded are the novel adsorbents, and we’ll continue to update you as the pilot progresses.
Last November, the OCWD Board of Directors approved a PFAS Treatment Policy.
The policy outlines key principles for addressing PFAS, including how the District will support retailers in paying for capital and operation and maintenance costs to treat for PFAS, and policies related to cost recovery efforts. The District continues to work with retailers to revise the policy and the draft agreements that will accompany it.
he Santa Ana Watershed Project Authority (SAWPA) Emerging Contaminants Task Force met this week to discuss the results from emerging contaminants sampling, including PFAS, that was conducted in the Santa Ana Watershed last August. It is anticipated the report will be finalized by this spring and will be presented by SAWPA at a public meeting of the Santa Ana Regional Water Quality Control Board later this year.
