STAC Workshop on Contaminants in Urban and Agricultural Settings

A wide range of contaminants of agricultural, human, and industrial origin have degraded water quality, and pose a threat to the health of fish and wildlife populations in the Chesapeake Bay and its watershed. A STAC workshop brought together researchers and water quality managers working in urban and agricultural settings to synthesize the current knowledge on contaminants of concern, and discuss opportunities for their reduction.

Fish Consumption Advisory Project

Joint project with the Chesapeake Bay Program Diversity Workgroup to develop effective communication tools for populations at high risk for PCB exposure through fish consumption in waters impaired by polychlorinated biphenyls (PCBs). These populations include children and those who are pregnant or may become pregnant in communities with high rates of subsistence fishing, and especially linguistically isolated populations or populations who do not have regular access to the publication avenues commonly used by state governments and municipalities.
