Housing Age Profile
Development in Westport unfolded across multiple decades, and the median build year of 1995 reflects a housing inventory where eras of construction are genuinely mixed — including portions that predate the federal prohibition on lead solder in plumbing.
Most homes in Westport were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Westport: 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.
Wherever 33% of local housing was built before solder rules changed — as is the case in Westport — a faucet-level sample closes the gap that aggregate utility data cannot.
