President’s Message: Water Infrastructure Projects Help Ensure Water Supply Reliability for Orange County

You may have heard about the California drought in recent news and headlines. Most recently on May 11, Governor Newsom expanded on the April 21 drought emergency proclamation which includes 41 total counties under the drought state of emergency. While this number may seem high, keep in mind this represents only 30% of the state’s population.

A statewide drought has not yet been declared and, so far, Southern California counties are not under the drought state of emergency.  Recurring drought is a feature of California’s climate and rest assured that OCWD and its 19 retail water agencies plan and prepare for an occasion such as this.

For decades, OCWD’s professional staff and Board have carefully planned and invested in long-term solutions to ensure that Orange County residents and businesses have enough water for their everyday needs – drought or no drought. I’m humbled and proud to highlight a few of those water supply projects:

Enhanced Stormwater Capture at Prado Dam: Following approvals by the U.S. Army Corps of Engineers (Corps) for the Prado Basin Ecosystem Restoration and Water Conservation Feasibility Study (Study), OCWD is planning for increased water storage behind Prado Dam.

This historic project announcement highlights the importance of water supply reliability and will add an additional 6,000 to 12,000 acre-feet of water annually into the Orange County Groundwater Basin (Basin) —creating a new water supply for approximately 60,000 people per year. Stormwater captured at Prado Dam is recharged into the Basin, which provides 77% of the drinking water that our 19 member agencies rely upon.

Without key partners like the Corps, water supply projects like this would not be possible. I want to thank the Corps for their longstanding partnership to collaborate with OCWD on innovative solutions. Whether it is public agencies working together or public-private partnerships, we need these strong alliances working together to make good investments that ensure water supply reliability for the region.

PFAS Pilot Project Recognized by ACWA as Exemplary Program

At the Association of California Water Agencies’ (ACWA) 2021 Virtual Spring Conference and Exhibition, OCWD received the Clair A. Hill Agency Award for Excellence, which recognized the District for launching the nation’s largest per- and polyfluoroalkyl substances (PFAS) pilot testing program.

Every year, ACWA identifies exemplary programs that demonstrate success in creatively addressing water industry issues, leadership in broad water-related issues, and excellence in agency management and operations.

“This award highlights our regional leadership and comprehensive approach to proactively and swiftly address 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 implementing projects like the PFAS pilot testing program. As always, we are committed to sharing our research results and best practices with the broader water industry so that everyone can benefit from this exemplary program.”

As part of the first phase of its pilot program, OCWD has successfully completed more than a year’s worth of testing and data collection where 14 different types of granular activated carbon and ion exchange products, as well as novel adsorbents, have been tested to determine the most cost-effective and best treatment solution to remove PFAS in the groundwater supply. The District recently began the second phase of the pilot program that will test new treatment media.

OCWD Completes 2019-2020 Engineer’s Report

The 2019-2020 Engineer’s Report on the Groundwater Conditions, Water Supply and Basin Utilization in the OCWD service area is now online on the District’s website. This annual Engineer’s Report has been prepared in accordance with the requirements of OCWD’s Act.

A summary of some key findings and highlights of this annual Engineer’s Report includes the following:

  • • Total water demands within the OCWD service area for the 2019-2020 water year that commenced on July 1, 2019 and ended on June 30, 2020 were 397,419 acre-feet.
  • • Precipitation within OCWD’s boundaries for the 2019-2020 water year averaged 13.38 inches, which was 99% of the long-term average rainfall.
  • • The average discharge of Santa Ana River flow past Prado Dam for the 2019-2020 water year was measured to 161,434 acre-feet, which represented 70% of the 30-year average flow.
  • • Groundwater stored in the OCWD groundwater basin increased by 36,000 acre-feet for the 2019-2020 water year.
  • • Despite dry conditions, the Basin continues to be reliable and plentiful. Through appropriate management, OCWD has successfully increased the yield of the Basin over time.

READ THE REPORT: View the 2019-2020 Engineer’s Report on the District’s website to learn more about the District’s water supply, annual and accumulated overdraft, recommended basin production percentage, water production costs, and much more.

Producer’s Corner: $1.6 Million DWR Grant to Help Mesa Water Enhance Local Groundwater Production Capacity

Mesa Water District (Mesa Water) will receive a $1.6 million grant to help improve water supply reliability in the region.

As part of a California Department of Water Resources (DWR) $55 million multi-year grant that was awarded to five regional water agencies in the Santa Ana Watershed Project Authority, Mesa Water is eligible to receive funding for the construction of Croddy Well 14, one of two new wells that will increase local groundwater production capacity.

Construction for Croddy Well 14, which can produce approximately 4,000 gallons per minute, is scheduled for completion in winter 2022. The funds will be available to Mesa Water once construction is completed and terms of the grant agreement have been met.

The DWR $55 million grant was awarded to OCWD, Inland Empire Utilities Agency, Western Municipal Water District, San Bernardino Valley Municipal Water District, and Eastern Municipal Water District. OCWD received $8 million of the DWR grant and selected Mesa Water along with four other water agencies to receive $1.6 million each to support the construction of new groundwater production wells.

Wild Secrets: Living on the Water's Edge

By Dick Zembal, Natural Resources Director

In this month’s Wild Secrets column, Natural Resources Director Dick Zembal shares a story about the various habitat that live and thrive in the OCWD watershed. Read his story below.

The idea of living on a river or lake appeals to many people but should you be so lucky you probably also know that your scenic ambiance is shared space. The water that OCWD manages for the residents of Orange County, on its way to people, grows habitat and fuels the lives of countless fellow creatures. The conveyance system, the river itself is a wildlife highway from the mountains to the ocean. The river gets more urbanized as it courses coastward but sustains wildlife along its entire length, all part of a healthy riverine system. You really cannot put water on the land for long without growing something. A wetted river channel is going to grow plants and insects, supporting fish, birds, and other life. If it does not, it is either quite ephemeral or something is seriously wrong. The closer you live to the water, the more your property functions as an extension of the riverbank and the more likely you are to experience riverine creatures, some quite pesky.  

It is May and the temperatures this season have already hit the 90s. The Santa Ana River flows full, bank to bank because there were late rains and there is nowhere else to put the water. In the early light, a tiny, winged creature emerges from the water and takes flight. By early morning, there are millions of them swarming in the micro-thermals just above the river and banks. These are breeding clouds of midges, mostly males attempting to attract a female. The swarms waft with the breeze and finally alight to rest on whatever plant life happens to be handy. They are drawn to the light, white, the bright. A porch light on a warm evening could attract thousands of them. A lighted pool in a nearby backyard has a film of them that clouds the water. A white wall is coated and darkened, a dark brown wall next door, nearly barren of them.

Midges do not bite but they do annoy with their swirling swarms, often at perfect head-height in massive abundance because of their synchronous emergence. They do fly lower and higher but there are so many of them. An early morning runner could cough in the tiny-bodied cloud if not careful. On the slightly more positive side, if this were Michigan, where they do bite, such a swarm would strike fear, fight, or flight in all within view of it.

PFAS Update

Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are chemicals that are prevalent in the environment and were once commonly used in many consumer products. They are part of a larger group referred to as per-and polyfluoroalkyl substances (PFAS). Due to the prolonged use of PFOA and PFOS, the chemicals are now being detected in the environment, including water sources throughout the United States.

PFAS have been detected in the Orange County Groundwater Basin. Despite playing no role in releasing PFAS into the environment, we must find ways to remove it.

OCWD provides regular PFAS updates to community stakeholders to inform them of the proactive measures that the District and 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.

PFAS INFORMATION: For the most recent updates and information or to sign up for our email updates, please visit OCWD’s PFOS/PFOA Resources page.

Quarterly North and South Basin Groundwater Cleanup Update

OCWD manages and protects the Orange County Groundwater Basin that underlies north and central Orange County, from which 19 cities and water agencies draw their water supply. OCWD implements a proactive groundwater and surface water monitoring program to protect the quality of the Orange County Groundwater Basin and ensure the water it provides meets or exceeds state and federal drinking water standards.

Industrial chemicals have impacted areas in the northern and southern parts of the groundwater basin; North Basin (near Fullerton, Anaheim, and Placentia) and South Basin (near Santa Ana, Tustin, and Irvine). OCWD is proactively seeking ways to clean up the pollution in a united effort with local and national regulatory agencies.

READ QUARTERLY UPDATE: OCWD has published its April 2021 update on activities in and around the North and South Basin sites. OCWD will continue to update stakeholders as the need arises.
