What's in Iola's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Iola Infrastructure Age
With 76% 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
The character of Iola's housing stock is one of deep historical layering — a median build year of 1964 signals a city built largely before the plumbing era changes of 1986 and 1970. Lead-soldered copper joints and, in the oldest properties, lead service lines are commonly present in this inventory. That context shapes what individual water testing may reveal, particularly in neighborhoods where the oldest housing is concentrated.
Over half of homes in Iola 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 Iola
Given current Iola property values, the remediation-to-equity ratio falls in the elevated tier — deliberate financial planning is a meaningful factor in how homeowners approach the documented water and safety issues on record here.
At 7.5% of home value, remediation costs in Iola represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $4,690–$10,780. Home values here are 33% below the Kansas average.
Iola: 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.
Although federal monitoring continues at the utility tier, Iola's 76% share of older housing alongside aggregate readings beyond the action mark raises lead to a near-term household step.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.

Iola: Flood History & Water Damage Risk
How does Iola's flood record connect to local water quality? The NFIP documents 89 claims — enough to signal recurring events — and 100% of ZIP codes carry FEMA flood zone status. That combination places flooding in the category of factors that can periodically affect water infrastructure, even if the area isn't among the highest-exposure communities in the NFIP dataset.
Iola has a moderate flood history with 89 FEMA claims averaging $35,120 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>$7,560</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.
