Drinking Water Watch
Drinking Water Watch is an application that lets any user (such as a waterworks owner or a Virginia consumer) view data that VDH-ODW maintains about a regulated, public water system or waterworks. A waterworks can be a community waterworks (C), a nontransient-noncommunity (NTNC) waterworks, or a transient noncommunity (NC) waterworks. This application does not apply to private wells or other water systems not regulated as a waterworks. The information that can be retrieved typically includes:
- size and type of population served,
- water system facilities (e.g., wells, intakes, treatment plant, etc.),
- sampling results reported to VDH-ODW,
- violations, and
- contact information.
The Glossary provides further information on terms used in the application and for help with navigation of the site/data base. Other tips are provided in Frequently Asked Questions (FAQs) produced by the Virginia Department of Health, Office of Drinking Water (VDH-ODW).

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).
