Contaminant Assessment Process

The Contaminant Assessment Process (CAP) is a nationally standardized and comprehensive method for assessing contaminant threats to land and wildlife on national wildlife refuges. The CAP, developed by the United States Geological Survey Biological Resources Division’s Biomonitoring of Environmental Status and Trends Program Togiak imageand the United States Fish and Wildlife Service’s Division of Environmental Quality, is used to document, assess, and monitor contaminant threats on refuges. A comprehensive list of known and potential contaminant issues is entered into CAP’s national database, and in Alaska a detailed report is prepared for each refuge. This information enables Service personnel to determine the magnitude and extent of contamination, initiate remedial activities or more detailed studies of potential problems affecting trust resources, and initiate pollution prevention activities. The CAP also helps managers select options that may reduce contaminant impacts on the habitats and species they manage. Upon completion, CAP reports are available in printed form, on CDs, or may be downloaded from the internet.
