Housing & Infrastructure in Hunnewell
With 63% 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
Federal plumbing rules changed in two stages — lead pipes were phased out before 1970, and lead solder was banned in 1986 — but in Hunnewell, where the median build year is 1977, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.
Over half of homes in Hunnewell 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 Hunnewell Homeowners
Within the Hunnewell market, documented remediation claims a significant slice of typical equity — the financial weight here is material.
At 2.6% of home value, remediation costs in Hunnewell represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $600–$3,100. Home values here are 67% below the Missouri average.
Lead Exposure Risk for Children in Hunnewell
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.
Although utility-side compliance with federal Lead and Copper requirements remains the system reference, that compliance does not extend down into interior plumbing. With 63% of Hunnewell stock built before the solder ban and aggregate readings at or beyond the action mark, a household-level sample becomes the practical way to close that information gap.
