Madison Water Utility's lead page doesn't say it tests individual homes. It points residents to certified drinking water labs instead, including the Wisconsin State Laboratory of Hygiene (608-224-6202, slh.wisc.edu) and Public Health Madison & Dane County. Ask the lab about sampling instructions, pricing and sample kits, since proper collection matters for a valid result. The Utility suggests at least two samples: one after water has sat in the pipes overnight and one after normal flowing use. Until you know, it advises running the cold tap until the temperature drops, then 30 more seconds, and using only cold water for drinking, cooking and infant formula. For questions about a lead service line, call the Water Utility at 608-266-4651. This covers Madison Water Utility customers.
