Mountain Home A F B Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Lead exposure in tap water isn't just a function of what water utilities deliver — it's also shaped by the plumbing inside individual homes. Structures built before 1986 may contain lead-soldered copper joints, and homes built before 1970 face an additional risk from lead pipes themselves. Mountain Home A F B's median build year of 2003 suggests the housing stock is broadly weighted toward the safer post-1986 era, but the age distribution shown above makes clear that the pre-1986 share of the inventory still represents a meaningful fraction worth understanding for anyone in an older home.
Most homes in Mountain Home A F B were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Mountain Home A F B: 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.
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 4% of Mountain Home A F B 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.
