Description The objective of this project is to analyze a suite of conventional and toxic chemicals in samples collected from pretreated wastewater from industrial facilities in the Puget Sound region. The selected facilities operate under State Waste Discharge permits to discharge pretreated wastewater to a publicly owned treatment works (POTW). The Washington State Department of Ecology will visit each facility once to collect water samples.

The first purpose of this project is to conduct compliance monitoring required under the National Pretreatment Program, a component of the National Pollutant Discharge Elimination System (NPDES) program. The second purpose is to screen for supplemental parameters that are not required to be monitored in order to advance research on chemicals of emerging concern (CECs) and other lesser studied chemicals. These pollutants can make their way to POTWs and, ultimately, to the Puget Sound. The supplemental parameters include organophosphate flame retardants (OPFRs), per- and poly-fluoroalkyl substances (PFAS), phenolic compounds, polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and semivolatile organic compounds (SVOCs).

This project supports efforts to protect and improve water quality in the Puget Sound, which plays a vital role in maintaining the region’s ecological and economic health.
