The quality of water delivered through Tucson Water's drinking water distribution system is shown in maps, charts, and tables. The objective is to provide water quality information on a system level: a broad view of water quality trends, historical water quality conditions, and current information about water characteristics important to Tucson Water customers.
These interactive maps are best viewed using Internet Explorer and are not compatible with Firefox browser. The maps contain a significant amount of detail and may require a fair amount of time to load.
The maps show each of Tucson Water's 17 different Water Quality Zones. Using the navigation buttons in the upper left, the viewer can zoom in, zoom out, and pan to access a particular area. As one zooms in, additional map information and details are displayed.
Each of Tucson Water's 22 EMPACT sampling points are shown as green dots. By clicking on the "info" button in the upper left and then on one of the EMPACT sampling points, information on chlorine, pH, temperature, and total dissolved solids is presented in a new window. If you have pop-ups disabled, re-enable them to view this information.
To see trends in water quality throughout the distribution system, select any of the water quality parameter buttons on the left side of the map. For historical trend charts of the selected water quality parameter, click a particular Water Quality Zone of interest to you. For localized information, go to the Neighborhood Water Quality Maps page.
In addition to the maps, summary water quality information about Tucson Water's supply sources and the overall distribution system is available at the links below. These will also open in a new window.
