How Old Is Hanna's Housing Stock?
With 45% 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
Prohibited from residential plumbing since 1986, lead solder divides Hanna's housing stock along a timeline that the median build year of 1999 straddles. A meaningful share of homes predates the ban - a configuration that places moderate aggregate pressure on plumbing-related lead risk, distributed unevenly across neighborhoods.
Most homes in Hanna were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Hanna
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.
Practically, the structural drivers in Hanna - 45% pre-rule stock and citywide monitoring at or beyond the regulatory benchmark - make an in-home draw the practical way to translate aggregate averages into the specific conditions at one address.
