Perryville Infrastructure Age
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 1998 mean for water safety in Perryville? 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 Perryville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Perryville: 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.
Wherever 39% of local housing was built before solder rules changed — as is the case in Perryville — a faucet-level sample closes the gap that aggregate utility data cannot.
