Recycled Water Research Program
Recycled Water Research Program
The State Water Board works with members of the recycled water community to identify knowledge gaps in recycled water research areas, for both potable and non-potable applications. Staff use this input to develop recycled water research funding priorities. Recycled water research funds are authorized through the Safe Drinking Water, Clean Water, Watershed Protection, and Flood Protection Act (2000 Water Bond, Proposition 13), the Water Quality, Supply, and Infrastructure Improvement Act of 2014 (Proposition 1), and the California Drought, Water, Parks, Climate, Coastal Protection, Outdoor Protection for All Act of 2018 (Proposition 68).
The State Water Board may dedicate up to three percent of the Bond funding allocated to recycled water, as well as three percent of repayments from Bond-funded water recycling construction loans, to recycled water research and development as set forth in Water Code section 79144. The availability of Proposition 1, 13, and 68 funding has provided the State Water Board with the opportunity to continue to facilitate recycled water research to advance the use of recycled water in California. The State Water Board authorized the Deputy Director of the Division of Financial Assistance to enter into agreements for recycled water research for the use of these funds in Resolution No. 2023-0009.

| Recipient | Regents of the University of California, Office of the President |
| Grant Funds | 2,500,000 |
| Status | Active |
Purpose:
This grant is for the National Alliance for Water Innovation (NAWI), which has an existing contract with the United States Department of Energy (U.S. DOE) to act as its Energy-Water Desalination Hub, and is for the purpose of conducting research to lower the cost and energy of desalination for reuse applications. Research focuses on improving efficiency by identifying new processes to reduce energy use, improve brine management, increase the longevity of system components, or develop methodologies to optimize operational efficiency.
The Regents of the University of California, Office of the President (UCOP) is the Recipient for the funds and will act as NAWI’s contracting authority. Specifically, the Research Grants Program Office (RGPO) within UCOP, working directly with NAWI, will manage the agreement for NAWI.

2021 Panel on Constituents of Emerging Concern (CECs) in Ambient Ecosystems
The State Water Board and Ocean Protection Council are jointly funding the Southern California Coastal Water Research Project to reconvene the Science Advisory Panel on Constituents of Emerging Concern (CECs) in Aquatic Ecosystems (Panel) to update its recommendations for monitoring and management of CECs in marine, freshwater, and estuarine ecosystems. The Panel will update the risk prioritization framework developed in the 2012 report, Monitoring Strategies for Chemicals of Emerging Concern (CECs) in California’s Aquatic Ecosystems, to address classes of chemicals, structurally-related chemicals, and data-poor chemical classes. The Panel will also provide the State Water Board with guidance on which classes of CECs have the potential to adversely impact marine, estuarine and freshwater wildlife, ecosystems, and beneficial uses, and will recommend management actions for the Water Boards to take to better address CECs in the aquatic environment.
The Panel began its deliberations with four two-hour public webinar meetings Oct 12-15, 2020. The Panel plans to deliberate through summer 2021 and will produce its final report in December 2021. For more information, please visit the SCCWRP website.
2018 Panel on Constituents of Emerging Concern (CECs) in Recycled Water
In accordance with the provisions of the Recycled Water Policy, Resolution 2016-0061, and Resolution 2017-0034, the State Water Board provided a grant to the Southern California Coastal Water Research Project (SCCWRP) to reconvene the 2010 Science Advisory Panel for Recycled Water that presented recommendations for monitoring CECs in recycled water. The Panel reviewed the conceptual framework developed in the 2010 report, evaluated the scientific literature since the Panel last met, and assessed the potential health risks associated with CECs in various water recycling qualities allowed under the California Code of Regulations, Title 22, and use of recycled water for augmentation of surface water reservoirs used to supply drinking water.

Recycled Water Research Needs in California
October 2015 Workshop
The State Water Board held a workshop on October 27-28, 2015 in Costa Mesa focused on the state of the science, monitoring techniques, and water treatment reliability for constituents of emerging concern (CECs) in recycled water. The goal of the workshop was to help the State Water Board identify knowledge gaps to identify and prioritize CEC monitoring and treatment activities that will ensure water supplies from recycled water, including potable reuse, are protective of public health and the environment. The workshop included presentations from experts regarding monitoring and treatment performance for CECs, as well as breakout sessions intended to review and discuss the most important CEC research needs. At the conclusion of each day, a summary of recommendations based on the breakout discussions was developed by the participants.
October 27-28, 2015 Workshop Summary
October 2014 Workshop
The California State Water Resources Control Board (State Water Board) held a workshop on October 29, 2014 to enhance interaction among the many water quality management agencies affected by transition of drinking water oversight from the California Department of Public Health to the newly created State Water Board Division of Drinking Water. The workshop focused on developing shared research priorities for water reuse and stormwater capture, and included 57 invited leaders from stormwater, wastewater treatment and drinking water entities, as well as staff from the State Water Board and Regional Water Quality Control Boards (collectively, Water Boards). The workshop considered issues associated with direct potable reuse, indirect potable reuse and surface water augmentation, and was organized around four research themes: (1) water quality and human health, (2) performance reliability (treatment, operations and training), (3) ambient water effects and (4) financial, environmental and social considerations. Participants were provided summaries of present knowledge and research needs within each theme area and were asked to help prioritize those needs.

2012 Panel on Constituents of Emerging Concern (CECs) in Aquatic Ecosystems
In April 2012, the State Water Board and the David and Lucile Packard Foundation jointly funded a scientific advisory panel to provide recommendations for monitoring CECs in aquatic ecosystems. The Panel provided recommendations in a report titled, “Monitoring Strategies for Chemicals of Emerging Concern (CECs) in California’s Aquatic Ecosystems.” In the report, the Panel recommended using a risk-based screening framework to identify an initial list of CECs to monitor in aquatic ecosystems. The Panel also recommended implementing an adaptive, phased monitoring approach to assess the presence of the CECs and their potential risk to the environment.

2010 Panel on Constituents of Emerging Concern (CECs) in Recycled Water
In accordance with the provisions of the Recycled Water Policy, a Science Advisory Panel was established to address questions about regulating CECs with respect to the use of recycled water. The Panel’s primary charge was to provide guidance for developing monitoring programs that assess potential CEC threats from various water recycling practices, including groundwater recharge and urban landscape irrigation. Under contract with the State Water Resources Control Board and using advice from a diverse stakeholder group, SCCWRP convened the Science Advisory Panel.
