Greenville 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
Although a small portion of Greenville's homes predate 1986, the median build year of 2009 indicates the majority of the city's residential plumbing was installed after lead solder was banned — which tends to reduce the plumbing-related component of lead exposure at the household level.
Most homes in Greenville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Greenville
In Greenville, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Greenville are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 46% above the Wisconsin average.
Greenville: 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.
In Greenville, the older-stock footprint runs at 22% — a contained slice — and aggregate utility readings land safely under the EPA action mark. That keeps lead off the local priority list, with a one-faucet draw remaining the only direct read on a specific address.
