Contaminant Source and Data Management Tools

SWAP Technical Assistance Document: The Application of GIS Technology and Data Management in States's Source Water Assessment Programs: The New England Interstate Water Pollution Control Commission (NEIWPCC) has published SWAP Technical Assistance Document: The Application of GIS Technology and Data Management in States= Source Water Assessment Programs, which addresses states' SWAP/ source protection related data quality, coordination, management, and distribution issues and concerns. This document highlights five states' approaches (Pennsylvania, Washington, Ohio, Iowa, and Nevada) to utilizing GIS in their Source Water Assessment Programs.

Farm*A*Syst and Home*A*Syst are national programs cooperatively supported by the USDA Cooperative State Research,

Education and Extension Service (CSREES), USDA Natural Resources Conservation Service (NRCS), and EPA. These programs provide assistance to private well owners, farmers and communities in risk assessment. Internet users can search for materials by state or by topic. The Resources button provides a map of the U.S. for obtaining contact and resource information by state.

Animal Waste Management:

Background information on the relationship between Animal Feeding Operations and water quality impairments, including ground water

EPA’s EIMS EPA's Office of Research and Development (ORD) has developed an Environmental Information Management System (EIMS) that focuses on the organization of descriptive information (metadata) for data sets, databases, documents, models, projects, and spatial data. The EIMS design also provides a repository for scientific documentation that can be easily accessed with standard Web browsers to place a virtual library on the desktop of EPA staff and others with Internet access.

GWPC’s EIMS - Environmental Information Management Suite is GWPC’s strategic approach toward managing production wells, UIC wells, source water, and watershed information from one toolkit. The EIMS program offers flexible integration of highly customizable data solution tools: a desktop GIS utility, Internet reporting, Internet GIS, wellbore schematic generation, and other visual data solutions. exit epa

Compendium of Tools for Watershed Assessment and TMDL Development (EPA 841-B-97-006) - The Compendium of Tools for Watershed Assessment and TMDL Development supports the watershed approach by summarizing available techniques and models that assess and predict physical, chemical, and biological conditions in water bodies. Tools include watershed-scale loading models; field-scale loading models; receiving water models, including eutrophication/water quality models, toxics models, and hydrodynamic models; and integrated modeling systems that, for example, link watershed-scale loading with receiving water processes.
