Constituents of Emerging Concern (CECs) in Aquatic Ecosystems

Advisory Panel on Constituents of Emerging Concern (CECs)

In April 2012, a scientific advisory panel named the “Ecosystems Panel (Panel)” provided recommendations for the monitoring of CECs in aquatic ecosystems. The recommendations are presented 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. The Panel also recommended implementing an adaptive phase monitoring approach to assess the presence of the CECs and their potential risk to the environment. The Panel was funded by the State Water Resources Control Board and the David and Lucile Packard Foundation. Water Board Staff has prepared a report that presents the Panel’s recommendations.

CEC Monitoring Dashboard

The CEC Dashboard summarizes data for 16 CECs downloaded from the California Environmental Data Exchange Network (CEDEN) database from 1993 – 2016 for all matrices (water, sediment, and tissue). The dataset originated from 50 different agencies and over 80 projects. The dashboard includes an interactive map and several interactive graphics. In the map, monitoring locations are shown by circles and identified by colors if CEC is detected or not detected at specific location. The graphics show the number of samples detected and not detected by year and CEC category. The features are interactive and more information can be displayed by clicking on the circle symbols or the graphics bar.
