Recycled Water – Constituents of Emerging Concern (CECs)
Advisory Panel on Constituents of Emerging Concerns (CECs)
In accordance with the provisions of the Recycled Water Policy, a CEC Advisory Panel has been established to address questions about regulating CECs with respect to the use of recycled water. The Panel’s primary charge is to provide guidance for developing monitoring programs that assess potential CEC threats from various water recycling practices, including groundwater recharge/reuse and urban landscape irrigation. On June 25, 2010, the CEC Advisory Panel provided recommendations to the State Water Board and California Department of Public Health in their Final Report.
Under contract with the State Water Resources Control Board (State Water Board) and using advice from a diverse stakeholder group, the Southern California Coastal Water Research Project (SCCWRP) convened the CEC Advisory Panel. The panel members are Dr. Paul Anderson (human health toxicologist), Dr. Nancy Denslow (biochemist), Dr. Jörg Drewes (civil engineer), Dr. Adam Olivieri (epidemiologist/risk assessor), Dr. Daniel Schlenk (environmental toxicologist), and Dr. Shane Snyder (analytical chemist).
Information on the Advisory Panel on CECs in recycle water is presented on the SCCWRP Website.
Public Hearing: Recommendations for Monitoring CECs in Recycled Water
The State Water Board will hold a public hearing on December 15, 2010 to accept comments on the recommendations for monitoring CECs in municipal recycled water used for groundwater recharge/reuse and landscape irrigation as presented in the Staff Report. The Staff Report is based on the recommendations presented in the CEC Advisory Panel’s report and provided by the California Department of Public Health (CDPH). The Staff Report also presents recommendations for additional research on CEC monitoring.

Additional CECs Information
Many of the questions to be addressed by the Advisory Panel on CECs in recycled water are also relevant to the ambient environment. The David and Lucile Packard Foundation has partnered with SCCWRP to support a second panel that will provide the State with recommendations on how to best limit the impact of CECs on our oceans, estuaries and wetlands. Information on the Science Advisory Panel for CECs in California’s Coastal and Marine Ecosystems is also available on the SCCWRP Website.
