Housing Age Profile
Plumbing risk in residential housing tracks directly to construction era: pre-1986 homes may have lead-soldered copper joints; pre-1970 homes may have lead pipes outright. Clark Mills's median build year of 1982 places the city in a moderate risk zone where neither era dominates the housing inventory. Understanding which side of the 1986 threshold a specific property falls on — and whether it predates 1970 — is the most actionable starting point for a homeowner trying to assess their own tap water exposure.
A significant portion of Clark Mills's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Older stock in Clark Mills represents 48% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
