The USGS's Toxic Substances Hydrology Program supplies "scientific information to improve characterization and management of contaminated sites, to protect human and environmental health, and to reduce potential future contamination problems." The website features comprehensible articles with links to supplementary materials addressing the latest research findings. Researchers can find information on computer simulations and statistical models. The website provides examples of the program's three major research components: subsurface point-source contamination; watershed and regional scale contamination; and methods development and fundamental research. Users can find a list and downloads to recent publications, a series of educational fact sheets, and an interesting photo gallery.
