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. Locust Hill's median build year of 1994 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.

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.

21% — that captures the slice of Locust Hill stock built before federal rules removed lead-bearing solder from new construction. Combined with system samples below the regulatory action mark, the picture points to a quiet baseline, with one-home draws as the only direct read on a specific address.
