Pulse of the Bay: Contaminants of Emerging Concern

The Regional Monitoring Program for Water Quality in the San Francisco Bay is an innovative collaboration of the San Francisco Bay Regional Water Quality Control Board, the regulated discharger community, and the San Francisco Estuary Institute. It provides water quality regulators with information they need to manage the Bay effectively. The Program issues a report each year, the Pulse of the Bay, that presents the latest results from monitoring and addresses a theme related to a timely water quality topic. The theme for 2013 is "Contaminants of Emerging Concern".

This edition of the Pulse provides a summary of the current state of knowledge of Contaminants of Emerging Concern (CECs) in the Bay. The report includes profiles of the CECs of greatest concern, which summarize information on their use, properties, recent findings from monitoring in the Bay and elsewhere, and developments in management.
