EPA Releases New Updated Version of DWMAPS

EPA has released a new 2.0 Version of its Drinking Water Mapping Application to Protect Source Waters (DWMAPS) tool.  DWMAPS 2.0 now provides real-time updates from data sources and improves interactivity within EPA’s GeoPlatform and with users’ own data.  DWMAPS is an online mapping tool that helps state and utility drinking water professionals in concert with other state and local mapping tools to update their source water assessments and protection plans. Watershed protection groups and source water collaboratives can also use DWMAPS to locate drinking water providers, potential sources of contamination, polluted waterways as well as information on protection projects and Source Water Collaboratives in their area
Certain features have been modified from the original version. For example, in DWMAPS 2.0 the “Potential Sources of Contamination” tool currently searches only for dischargers permitted through the National Pollution Discharge Elimination System (NPDES) program. Users may explore additional point sources regulated by other programs in the DWMAPS 2.0 layer list. .  DWMAPS can be accessed directly at: https://www.epa.gov/sourcewaterprotection/dwmaps.  For more information or questions, please contact Sherri Comeford of EPA at Comerford.Sherri@epa.gov or (202) 564-4639.
