Harrisburg 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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Harrisburg, the median build year of 1997 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Harrisburg were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Harrisburg
In Harrisburg, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Harrisburg are relatively low compared to home values. The $300–$1,600 estimated range is a small fraction of median property value. Home values are 37% above the Missouri average.
Harrisburg: 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.
Routinely in Harrisburg, where 39% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
