BETTER ASSESSMENT SCIENCE INTEGRATING POINT AND NONPOINT SOURCES (BASINS)
Description:
Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) is a computer-based system for environmental analysis developed by EPA in response to a growing demand for integrative watershed- and water-quality-based assessments. Developed for use by EPA, state, tribal, and local agencies, BASINS facilitates the examination of environmental information, provides an integrated watershed assessment and modeling framework, and supports the analysis of point and nonpoint source management alternatives. A specific use of BASINS has been to assist in the development of Total Maximum Daily Loads (TMDLs). BASINS integrates a geographic information system (GIS), national watershed data, and state-of-the-art environmental assessment and modeling tools into one package. The software makes it possible to quickly assess large amounts of point and nonpoint source data in a format that is easy to understand. Users can assess water quality at selected stream sites or throughout an entire watershed for nutrients, pathogens, pesticides, toxics, and sediments. Because BASINS integrates environmental data with analytical tools and modeling programs, it can support the development of cost-effective approaches to environmental protection.
