About
The Toxic Contaminants Workgroup (TCW) was established in 2014 after the signing of the Chesapeake Bay Watershed Agreement. This workgroup exists to accomplish the agreement's Toxic & Emerging Contaminants Outcome, working to reduce the amount and effect of toxic contaminants, such as PCBs, plastics, mercury and PFAS, on the waters, lands, fisheries, wildlife and communities of the Chesapeake Bay watershed through an increased understanding of their impacts and mitigation options.
While Management Strategies to support the 2025 Watershed Agreement are being developed, work by the TCW will be guided by member priorities and past workplans. Learn more:
