Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Carterville's Housing Stock?
With 45% 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
Carterville's residential inventory spans multiple construction eras, with the median build year of 1981 landing in a zone where pre- and post-1986 homes are both well represented. That split matters because homes built before 1986 may contain lead-soldered copper joints — a plumbing practice banned that year — while those built before 1970 face the additional possibility of lead pipes in the service line. Whether a specific household sits on the older or newer end of this distribution is the primary variable shaping its individual exposure risk.
Most homes in Carterville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Carterville: Remediation Cost in Perspective
Although the Carterville remediation share is moderate, it remains reachable for most homeowners who plan for the expense in advance.
Remediation costs are moderate relative to home values in Carterville. The estimated $1,250–$4,000 range is manageable for most homeowners but still worth budgeting for. Home values are 0% above the Illinois average.
Protecting Children from Lead in Carterville
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.
Locally, 45% of Carterville homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.

Climate-Related Water Risk for Carterville
NFIP data for Carterville shows a modest claim record and limited flood zone footprint — a combination that places flood exposure well below the threshold where water quality becomes an active planning concern. The connection between flooding and water safety is real during major events anywhere, but it stays in the background here rather than rising to an active local risk factor.
Carterville has a relatively low flood history with 2 FEMA claims on record. While risk is limited, severe weather events can still impact water infrastructure.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,400</strong> remediation cost per household.
