Housing & Infrastructure in Three Rivers
With 83% 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
When a city's housing median build year is 1953, as in Three Rivers, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Three Rivers 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 Three Rivers Homeowners
In Three Rivers, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Three Rivers are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 55% below the Massachusetts average.
Lead Exposure Risk for Children in Three Rivers
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.
Routinely in Three Rivers, where 83% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
