Contaminants of Emerging Concern

Contaminants of emerging concern (CECs) are chemicals that have entered the environment through human activities and are not routinely monitored for and are currently unregulated. They have been detected in humans or other organisms and have been found to persist in the environment. Examples include pharmaceuticals and personal care products (PPCPs), hormones, flame retardants (PBDEs), and flame repellents/non-stick surface coatings (PFASs).

A number of efforts have been undertaken within the Delaware River Basin to identify, understand, and prioritize CECs, including work that the commission does with the basin states and the U.S. EPA to assess the main stem Delaware River. A three year effort by DRBC to investigate the presence and concentration of PPCPs, PFASs, and PBDEs in the ambient waters of the tidal Delaware River concluded in 2009. The commission has an ongoing monitoring program for PFAS/PFC in the main stem Delaware River, examining surface water, fish tissue, and sediment.
