Housing & Infrastructure in Madison
With 57% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Madison's median build year of 1987 reflects a housing stock where these older materials are a pervasive feature - not a rare legacy - of the residential plumbing landscape.
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
In Madison, property wealth outpaces what documented remediation typically demands - the equity burden lands well within the low tier.
Remediation costs in Madison are relatively low compared to home values. The $1,100–$3,000 estimated range is a small fraction of median property value. Home values are 1% below the New Hampshire 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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted - but 57% of the Madison inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.
