How Old Is Kansas's Housing Stock?
With 41% 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
Because Kansas's housing stock spans a wide range of construction eras, the median build year of 1999 lands in a zone where two distinct risk populations share the same residential market. Homes built before 1986 may have lead-soldered copper plumbing joints — that practice was federally prohibited in 1986 but remained standard until then. The fraction built before 1970 face an additional risk: lead pipes used for service line connections were common before that decade, meaning both the pipe and the solder may be lead-containing in the oldest structures. Residents in mid-century or earlier homes face a different risk environment than neighbors in houses built after 1986, even if they drink from the same utility's supply — and that property-level divergence is what makes the age distribution above more diagnostic than the city-wide median alone.
Most homes in Kansas were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Kansas: Remediation Cost in Perspective
Throughout Kansas, fixing documented water and safety issues carries an equity weight that moves remediation out of routine planning territory and into structured financial decision-making.
At 2.4% of home value, remediation costs in Kansas represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,100–$4,100. Home values here are 35% below the Oklahoma average.
Protecting Children from Lead in Kansas
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.
Despite citywide averages serving as the standard public reference point, those aggregates cannot resolve what is happening at one specific faucet — and where 41% of Kansas homes come from before the solder rule or where utility samples sit at or above the action mark, the gap between system data and faucet reality matters more than it does in lower-exposure communities. An in-home draw closes that gap, with certified filtration through retailer networks available where confirmed faucet results warrant additional measures.

Climate-Related Water Risk for Kansas
100% of ZIP codes in Kansas are mapped into FEMA-designated flood zones, and the NFIP records 35 claims reflecting a multi-event flood history. That combination places local flood exposure in the range where water-quality implications deserve at least periodic attention.
Kansas has a moderate flood history with 35 FEMA claims averaging $13,155 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>$2,200</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.

What You Can Do in Kansas
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. Filters rated for Stage 2 DBP Rule can reduce the most common contaminant found in Kansas's water.
- Check your home's plumbing. With 41% of homes built before 1986, lead solder is a real possibility.
