Over half of homes in Madison were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Madison Homeowners
Property equity in Madison runs well ahead of estimated remediation costs — a cost-to-value ratio that sits in the low tier, meaning documented water and safety issues here are the kind homeowners can plan to address without treating the expense as a significant budget event relative to what their homes are worth.
Remediation costs in Madison are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 1% above the Pennsylvania average.
Lead Exposure Risk for Children in Madison
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 89% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Madison.
