Environmental Health - Toxic Substances Hydrology Program
Environmental occurrence and distribution studies are conducted on environmental contaminants prioritized based on their likelihood of entering, and persisting in, the environment, and their potential environmental health consequences. These studies focus on environmental settings likely to be vulnerable to point and non-point source contamination. These studies address a wide range of environmental media (groundwater, surface water, sediment, soil, and air), and yield datasets on contaminant concentrations, including non-detections, and mixtures, which provide a foundation for additional research on contaminant sources, transport, persistence, fate, and effects.
The Toxic Substances Hydrology Program's bibliography has 322 publications with environmental contaminant data from our investigations. Most are online reports with data tables from the U.S. Geological Survey (USGS).
The Sediment-bound Contaminant Resiliency and Response (SCoRR) Mapping Application was developed to allow users to visualize and view information generated during this study. Additional datasets including Census data, the National Land Cover Database, and National Hydrography data are also provided for users to generate custom maps.
