President’s Message: Addressing PFAS Proactively, Swiftly, and Fairly
As Orange County’s groundwater authority, the Orange County Water District (OCWD; the District) upholds its commitment to manage, replenish, and protect one of the region’s most valuable assets – the Orange County Groundwater Basin (Basin).
Per- and polyfluoroalkyl substances (PFAS), a group of thousands of manmade chemicals that are used in common everyday consumer materials and products to make them non-stick and/or resistant to water, oil, and stains, has been detected in the Basin. Our staff is doing an incredible job addressing this issue and ensuring that our water continues to meet all state and federal drinking water standards. These efforts include testing treatment techniques, investing in new equipment to support lab analysis, constructing several dozen treatment facilities for impacted water agencies, and holding the responsible parties accountable for releasing these chemicals into our water supply.
We’re doing all that we can to proactively and swiftly address a very costly health threat issue that we did not cause. This is why we’re strongly urging Congress to preserve the polluter pays principal and vote no on bills like the PFAS Action Act of 2021 (H.R. 2467) that impose liability on water agencies unless amended to exclude public water and wastewater agencies from PFAS liability. We recognize certain PFAS chemicals and other constituents of emerging concern should be carefully monitored and treated, but we believe it is inappropriate to treat public agencies cleaning up the problem in the same manner as the polluters who caused the issue.
As passed by the House, H.R. 2467 would expose water agencies with across-the-board liability for PFAS-related cleanup that simply receive and treat water supplies. This would adversely impact the District’s ability to recover the costs of its ongoing PFAS remediation activities by possibly imposing liability on the District in connection with its groundwater replenishment programs and treatment and disposal activities. A water utility that complies with applicable and appropriate federal management and treatment standards should not be responsible for current and future costs associated with PFAS clean-up.
OCWD urges Congress to provide an explicit liability exemption for water and wastewater agencies should federal PFAS legislation designate these chemicals as hazardous under the Comprehensive Environmental Response, Compensation, and Liability Act’s (CERCLA) much like the exemption afforded to airports.
We’re working hard to protect Orange County’s water supply and the Basin which supplies 77 percent of the water supply to 2.5 million people in north and central Orange County. While we continue to stay committed to addressing PFAS in the Basin, we must do so in a way that is cost-effective and fair to our ratepayers.
Director Cathy Green Garners Statewide Support for ACWA VP
OCWD Director Cathy Green is securing statewide support for her nomination as a candidate for Vice President of the Association of California Water Agencies (ACWA)—the largest statewide coalition of public water agencies in the United States.
As a longtime leader in the water industry, Director Green has worked to enhance water management, water quality, and water supply diversity and reliability to sustain our communities and our economy. Additionally, she has helped to effectively advocate for federal and state funding for water infrastructure and treatment projects, including Forecast-Informed Reservoir Operations (FIRO), groundwater cleanup, and water storage projects.
Her experience includes being an active member of ACWA for the past nine years, serving on various ACWA Boards and Committees since 2012. Currently, she is a member of ACWA’s Executive Committee (since 2019) and Board of Directors (since 2012) and is serving her second term as Vice Chair of the ACWA Region 10 Board of Directors. Director Green also serves on ACWA’s Water Quality Committee (since 2012), and its Energy Committee (since 2020). Previously, she served two terms (2014-15 and 2018-19) as Region 10 Chair, and two terms on ACWA’s State Legislative Committee (2012-2015).
“It is an honor to receive such overwhelming support from my colleagues throughout California,” said Director Green. “My vision for ACWA is to embrace its motto, Bringing Water Together, which for me is about unifying ACWA members and working collaboratively to advance statewide issues and policies that ensure a safe, affordable and reliable water supply for all Californians.”
The election for ACWA President and Vice President will take place at the ACWA 2021 Fall Conference. More information about Director Green’s experience and qualifications can be found in the press release and webpage.
FIRO Pilot Program Enhances Water Supply Reliability
Through a partnership with the Center for Western Weather and Water Extremes at UC San Diego’s Scripps Institution of Oceanography, U.S. Army Corps of Engineers (USACE), and California Department of Water Resources (DWR), OCWD is implementing Forecast-Informed Reservoir Operations (FIRO) to increase water supply reliability for the region.
A new report evaluating a pilot program (FIRO) to use advanced weather and streamflow forecasts to enhance water storage capabilities at Prado Dam in Riverside County found that enough water could be conserved to supply an additional 60,000 people per year.
Prado Dam was constructed in 1941 by USACE for flood risk management, with a secondary benefit of stormwater capture for water supply. Many dams in the west, including Prado Dam, are regulated by USACE-issued water control manuals, which do not take advantage of modern precipitation and streamflow forecasting capabilities. FIRO is a research and operations partnership that uses data from watershed monitoring, and modern weather and hydrologic forecasting, specifically the study of atmospheric rivers, to help water managers selectively retain or release water from reservoirs in a manner that reflects current and forecasted conditions.
“We are excited to partner with Scripps and the USACE on this project, which increases water supply and reliability for the region,” said OCWD President Steve Sheldon. “Local stormwater capture is important because it lessens demand on imported water supplies, which are more costly than groundwater.”
More information about the FIRO pilot program, its partners and the report can be found in the press release or by watching the short video below.
EPA Announces $131 Million WIFIA Loan for OCWD’s PFAS Treatment Program
The U.S. Environmental Protection Agency (EPA) announced a $131 million Water Infrastructure Finance and Innovation Act (WIFIA) loan, supporting OCWD’s efforts to remove per- and polyfluoroalkyl substances (PFAS) from drinking water found in local groundwater. By helping finance this project, EPA’s WFIA loan will protect public health from PFAS while reducing dependence on costly imported water for 2.5 million residents in Orange County.
OCWD’s PFAS Facilities Treatment Project is ensuring a safe and reliable drinking water source by building water treatment plants within the county. In 2020, dozens of wells that pump water from the Orange County Groundwater Basin were removed from service after the state of California lowered the Response Level advisories of two PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Consequently, local water suppliers had to rely on more costly imported water from Northern California and the Colorado River in order to meet the needs of their customers.
“OCWD is committed to proactively and swiftly addressing PFAS that have been detected in local groundwater supplies,” said OCWD President Steve Sheldon. “Our staff have done an outstanding job responding to this critical water quality issue by expediting the design and construction of the PFAS treatment facilities.”
OCWD provides regular PFAS updates to community stakeholders to inform them of the proactive measures that the District and its retail water agencies are taking to address PFAS in the Basin and continues to participate in important dialogues and research initiatives with people across the country on developing long-term solutions.

Wild Secrets: Night Prowlers
By Dick Zembal, Natural Resources Director
In this month’s Wild Secrets column, Natural Resources Director Dick Zembal shares his stories about some of the most common large mammals, night prowlers, of the Prado Basin.
The wildlife that OCWD’s Natural Resources Department staffs expend the most effort monitoring and managing are birds and fishes, so you have not heard much in these newsletter stories about large animals, although the Bald Eagle is certainly no small fry. Birds occupy the available niches, environmental cubbies, such that their abundance and diversity is an excellent indicator of environmental health. For example, we track the endangered Least Bell’s Vireo and its habitat as an indicator of riparian health to reveal the strengths and weaknesses in our stewardship, so we can adapt management strategies as needed. The megafauna of the Districts’ wildlands are out there, but how well those populations are doing is positively inferred from the overall health of the Prado ecosystem and incidental observations rather than by detailed study. Many of these species are most active in low light, crepuscular, or darkness, nocturnal.
The Mule Deer is the largest native herbivore in the Prado Basin. Bucks average about 200 pounds, exceptionally to over 400 pounds; does are smaller, weighing in at 95 – 198 pounds. Our deer are browsers of shrubs, trees, and forbs as opposed to grazing mostly on grasses as do cattle, bison, and rabbits. Deer herds are generally multigenerational groups of related females. Males typically are solitary or seen in small groups except during the rutting season in the fall. The males carry antlers (bony in contrast to horns which are keratinaceous) that are dropped annually in winter and regrown, starting immediately after shedding. Females usually birth two spotted fawns in spring following 190 – 200 days gestation. The young are independent after 60 – 75 days. California Mule Deer follow traditional migration routes to take advantage of browse that is seasonally available, usually at higher elevations. That has got to be a bit different in Prado, given the seasonal pool with its log jams, size, and persistence in some years. Also, local habitat adjacent to Prado Basin is confined to narrow corridors along the creeks and river, and up into the Chino hills. A study of the Prado herd’s movements and lineages was proposed by the United States Geological Survey (USGS) but never unfolded.
Deer sightings are sporadic in Prado Basin but became noticeably more abundant in recent years. I have been delighted to come upon them, close enough to see their characteristic predator-escape locomotion, springing away, stiff-legged up and down with all four legs touching the ground at once, then rebounding like on pogo sticks, called stotting or pronging. The trails and roads we rely upon for surveying wildlife and to access project features like the recent Sediment Demonstration Project comprise important travel lanes for large mammals as evidenced by the abundance of sign. Tracks and scat are telltale, but you need to know how to decipher deer from pig. Both are cleft-hooved (two-toed imprint) but the deer toes are more pointed and the dew claw is smaller, round and centered below the toe like the dot in an exclamation mark. Alas, the dew claws often don’t show. Based upon the sign, pigs are generally more abundant than deer.
