What's in Kewanee's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Kewanee Infrastructure Age
With 89% 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.

Housing Age Profile
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Kewanee's median build year of 1941 places it squarely in that category.
Over half of homes in Kewanee were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Kewanee
In Kewanee, the equity impact of remediation sits at the elevated end of the scale — the cost-to-value ratio is high enough that most homeowners are weighing a genuine financial decision, one where planning and scope prioritization are practical tools rather than optional considerations, and early documentation of what needs addressing determines the shape of the commitment.
At 3.2% of home value, remediation costs in Kewanee represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,600–$3,300. Home values here are 59% below the Illinois average.
Kewanee: 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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 89% pre-rule share in Kewanee keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Kewanee: Flood History & Water Damage Risk
Within the NFIP's national dataset, Kewanee falls in moderate-exposure territory — 15 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Kewanee has a moderate flood history with 15 FEMA claims averaging $1,579 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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.
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.
