Dorchester Infrastructure Age
With 69% 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.

Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Dorchester - it's the dominant profile. The median build year of 1975 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Dorchester were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Dorchester
At current valuations, Dorchester sits in the low remediation-share tier - the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Dorchester are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 24% below the Wisconsin average.
Dorchester: Lead Risk & Vulnerable Populations
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.
Older interior plumbing shapes the local picture: 69% of Dorchester homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.
