How Old Is Travis Afb's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
What does a median build year of 1995 mean for water safety in Travis Afb? It means the housing stock straddles two key plumbing thresholds: the 1986 federal ban on lead solder in copper plumbing, and the pre-1970 era when lead pipes were commonly installed for service lines. A meaningful share of homes predates one or both of those cutoffs, creating varied risk levels across the city's housing inventory.
Most homes in Travis Afb were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Travis Afb
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.
Despite citywide averages reading cleanly under the federal action threshold, the way utilities pull samples — from a representative subset rather than door-to-door — leaves room for individual buildings with older interior lines to behave differently than the aggregate suggests. With only 30% of Travis Afb stock predating the solder rule, that residual subset is small but real, and a draw-test kit gives the only direct read on what comes out of one faucet on a given morning.
