How Old Is Kerman's Housing Stock?
With 42% 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
For a city with a median build year of 1998, Kerman carries a housing profile that straddles the 1986 federal ban on lead solder in plumbing. Neither predominantly new nor predominantly old, the stock presents a moderate aggregate risk environment - with individual risk varying sharply depending on when and where a specific home was built.
Most homes in Kerman were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Kerman: Remediation Cost in Perspective

Protecting Children from Lead in Kerman
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.
Locally, 42% of Kerman homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.
