Overview of the Toxic Substances Hydrology Program role in investigating the occurrence and fate of agricultural chemicals with links to investigations, headlines, on-line fact sheets, new publications, bibliographies and photo gallery.
Describes and illustrates that a broad range of chemicals found in residential, industrial, and agricultural wastewaters commonly occur in mixtures at low concentrations downstream from areas of intense urbanization and animal production.
The Contaminant Biology Program investigates contaminant exposure and effects on fish, wildlife, and other organisms, their habitat and ecosystems. Links include description of projects, research centers, and news.
Research findings and examples of application to real problems--biosolids have high concentrations of household contaminants compared to treated liquid wastewater effluent.
Homepage of the Abandoned Mine Lands (AML) initiative programs supporting actions to remedy contaminations associated with hard rock mining. Includes data from the Upper Animas River and Boulder River, bibliography of reports, and pictures.
The Restoration Technologies Branch (RT) responds to client needs for bioengineering research/technical assistance in reducing pollution. Current projects are on hydropower generation, control of exotic species, and acid mine drainage.
