Contaminants in bed sediment from surface waters collected in the Chesapeake Bay Watershed, 2021-24

This data release provides contaminant data from bed sediment collected from small streams between 2021 and 2024 in the Chesapeake Bay Watershed. These data are part of a larger study designed to determine how conservation practices are affecting local stream ecosystem health, which stressors are negatively impacting streams, and which landscape characteristics are associated with better or worse conditions in local streams. Samples were analyzed at RTI Laboratories Incorporated, Livonia, Michigan and The U.S. Geological Survey, Florence Bascom Geoscience Center, Wetland Ecosystem Ecology and Biogeochemistry Lab, Reston, Virginia. Exact site location information for these sites is not available as a result of privacy concerns.
