Key Contaminants Detected in Chillicothe
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Chillicothe's Housing Stock?
With 68% 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
Heavily weighted toward older construction, Chillicothe's housing stock carries a median build year of 1979. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Chillicothe were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Chillicothe: Remediation Cost in Perspective
How does remediation fit within the broader financial picture for Chillicothe homeowners? The equity share is moderate — large enough that treating it as a real planning consideration makes sense, and manageable enough that most homeowners have a clear path to addressing documented water and safety issues when they approach the commitment with deliberate advance budgeting rather than as an unplanned expense.
Remediation costs are moderate relative to home values in Chillicothe. The estimated $2,000–$4,100 range is manageable for most homeowners but still worth budgeting for. Home values are 18% below the Illinois average.
Protecting Children from Lead in Chillicothe
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 68% pre-rule share in Chillicothe keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Climate-Related Water Risk for Chillicothe
FEMA data places 100% of Chillicothe's ZIP codes inside designated flood zones, and the NFIP claim record confirms the real-world impact: 1133 filed claims representing decades of documented flood events with consequences for property and, at sufficient severity, for local water infrastructure.
Chillicothe has a significant flood history with 1,133 FEMA flood insurance claims on record, averaging $8,281 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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>$3,000</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
