Tools and Technical Assistance

A variety of tools are available to aid community planners, public water supply operators, and members of local source water protection teams in developing source water assessments. The tools include general information on water quality and surface and ground water hydrology, as well as specific information on watersheds, aquifers and federally owned public water supplies.
  • Protection Tools 
    Provides links to information resources or programs that may be of use when implementing protection measures for drinking water sources.
  • Susceptibility Determination Tools 
    Provides links to tools and databases that might be of use in determining the susceptibility of a source of drinking water to contamination. The list includes risk assessment and health effects information.
  • Delineation Tools 
    Provides links to tools and databases that might help in mapping areas that are the source of a drinking water supply.
  • Potential Contaminant Source Inventory Tools 
    Provides links to tools and databases that might be of use in completing contaminant source inventories.
Many organizations can assist with protection planning. A good place to start is with your state's source water program.
