Is Madison Tap Water Safe To Drink?
Yes! The tap water is safe to drink.
Yes. Tap water in Madison, Wisconsin, is treated and monitored by Madison Water Utility and must meet U.S. Environmental Protection Agency and Wisconsin Department of Natural Resources safety standards.
Most residents can safely drink it directly from the tap. Homes with older plumbing may have lead service lines or fixtures, so using cold water for drinking and cooking and flushing stagnant water can reduce exposure.

Source of Water in Madison, United States
Madison, Wisconsin’s tap water comes entirely from groundwater, not from nearby lakes such as Lake Mendota. The Madison Water Utility pumps it from deep wells that draw from the regional sandstone aquifer.
Rain and melting snow replenish this underground water supply as water moves through soil and rock. Before distribution, the water is treated and disinfected to meet federal and Wisconsin drinking water standards.
Madison Drinking Fountains
Public drinking fountains in Madison, Wisconsin, are generally safe to use because they receive treated municipal water regulated under Wisconsin and federal drinking-water standards. Water quality can vary if a fountain is poorly maintained, temporarily shut off, or affected by plumbing conditions.
Use fountains that are clean, operating normally, and free of advisory or closure notices. Let the water run briefly before drinking, especially after the fountain has been unused for a while.
