How Old Is Cromwell's Housing Stock?
With 58% 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
Because the majority of Cromwell's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1987 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Cromwell were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cromwell: Remediation Cost in Perspective
In Cromwell, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.

Protecting Children from Lead in Cromwell
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 Cromwell, where 58% 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.
