Report Out on Monitoring Chemicals of Emerging Concern

Report on CECs available on Water Resources Control Board site

The State Water Resources Control Board has posted a report by a science advisory panel with recommendations for monitoring chemicals of emerging concern (CECs) in California’s aquatic ecosystems.

The report examines the issues associated with CECs in the state’s aquatic systems that receive discharge of treated municipal wastewater effluent and storm water.  A panel of experts in chemistry, biochemistry, toxicology, chemical and risk assessment, engineering and coastal and marine environmental health sciences convened in October 2009 to examine the issue. The panel’s report makes several recommendations, including monitoring trigger levels (MTLs) for CECs that pose the greatest risk to aquatic systems based on published effects concentrations.

The report is available here.
