How Old Is Congerville's Housing Stock?
With 67% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Congerville — it's the dominant profile. The median build year of 1975 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Congerville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Congerville: Remediation Cost in Perspective
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Congerville is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Congerville are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 32% above the Illinois average.
Protecting Children from Lead in Congerville
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.
67% — that captures the slice of Congerville housing dating from before the federal ban on solder containing lead. It pairs with aggregate utility readings that either approach or cross 0.015 mg/L, the benchmark set under the EPA Lead and Copper Rule. Together, the two figures shift one-home reads into a standard household-level confirmation, particularly for families with kids. A certified lead-removal filter is available through retailer-verified channels if a kit returns results that warrant additional measures.
