DEQ Public Water Systems Layer Updated.
The Source Water Protection Program of the Montana Department of Environmental Quality provided NRIS with an update of the public water systems database for the first time since 2008. The data is available as an ESRI shapefile at http://nris.mt.gov/nsdi/nris/shape/pws.zip and may be viewed on-line with the Montana Digital Atlas. The tabular version of the database may be viewed with the Source Water Protection Program Query System, and a complete description of the data is available at http://nris.mt.gov/nsdi/nris/pws.html.
