Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Congress banned lead solder in residential plumbing in 1986, drawing a clear line in housing risk by era. Fort Wainwright's median build year of 2005 puts most of its residential stock on the newer side of that boundary — a profile that generally correlates with lower plumbing-sourced lead exposure across the city.
Most homes in Fort Wainwright were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Fort Wainwright
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, Fort Wainwright's indicators line up: aggregate readings pass under the regulatory benchmark and the pre-rule housing footprint at 18% keeps lead in a background position.
