How Old Is Allardt'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
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. Allardt's median build year of 1995 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 Allardt were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Allardt
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.
Through the multi-year window of EPA Lead and Copper Rule monitoring, Allardt has stayed under the action mark. Paired with a 26% pre-rule housing share, the result places lead in a lower-priority spot on the local picture — without erasing the structural gap between citywide averages and what arrives at one specific tap.
