Water Utility

Madison-Madison Water Utility is making its Annual Drinking Water Quality Report available in Spanish.

The report is based on 2007 data and describes the source of Madison's tap water-a deep groundwater aquifer-and what citizens can do to help protect and maintain the quality and quantity of our drinking water. It also provides links to on-line resources for reducing use of toxic substances around the house, and better home and garden practices that help to conserve water.

This Spanish version of the report is available in pdf format on the Water Utility's website at http://www.ci.madison.wi.us/water/Documents/WaterQuality.Spanish.final.pdf as well as in paper format. Customers may also find copies at Centro Hispano, or upon request at the utility by calling 266-4654.

The report also details the chemical contaminants that have been detected in Madison's water. Most of the chemical contaminants are naturally occurring elements that arise from dissolution of the rock that forms the underground aquifer. These substances are harmless at the levels found, but they can cause aesthetic problems. For example, because hardness minerals such as calcium and magnesium can leave spots or residue on dishes and fixtures, they require more soap for cleaning, and they cause scales that can clog pipes or appliances such as water heaters and dishwashers. Most homeowners have a water softener to remove the hardness.

The annual report provides a snapshot of water quality for all Madison's wells. For more detailed information on the specific wells that serve an address, customers are encouraged to visit our website, http://www.cityofmadison.com/water/ to obtain a detailed water quality report.
