Evansville 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
A median build year of 1996 in Evansville points to a housing stock where post-1986 construction is the norm. That matters because lead solder in plumbing — banned federally in 1986 — is a primary pathway by which older homes can elevate tap water lead above what enters the distribution system.
Most homes in Evansville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Evansville: 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.
Generally, the structural picture for Evansville runs in a quiet direction. Aggregate sampling rests under the federal action benchmark, and 28% of housing comes from the pre-rule era — a contained local footprint. That dual signal keeps lead in the background of local concerns, while a one-faucet measurement still answers a different question than any system average can: what is actually flowing from one specific tap on a given morning.

What You Can Do in Evansville
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
