Drinking Water Watch

Drinking Water Watch is an application that lets you view data that VDH-ODW maintains about your water system(s). The information includes:

  • size and type of population served,
  • water system facilities (Ex. wells, intakes, treatment plant, etc.),
  • treatment used,
  • sampling results reported to us,
  • violations, and
  • contact information.

This glossary  is available for further information on terms used in the application and for help with navigation of the site. Other tips are provided in this FAQ produced by Montana DEQ.

Geographic Information Systems (GIS)

ODW leverages the power of GIS using Esri’s ArcGIS® software suite. GIS enables ODW to better visualize and spatially analyze public drinking water data.

ODW has been able to use GIS to visualize data in novel ways on the web. Using Esri’s story map design, ODW has produced a map to visualize the distribution of water treatment processes employed in Virginia, such as chloramines and membrane filtration, and special source water categories such as groundwater under the influence of surface water (GUDI).
