What's in Sedan's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Sedan Infrastructure Age
With 83% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Sedan's median build year of 1953 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Sedan 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 Sedan
What does the elevated remediation share mean for Sedan homeowners financially? A serious commitment — one that calls for structured planning rather than an ad-hoc response.
At 3.3% of home value, remediation costs in Sedan 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 57% below the Kansas average.
Sedan: 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 83% pre-rule share in Sedan keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Sedan: Flood History & Water Damage Risk
Flood risk in Sedan occupies the middle ground: 1 NFIP claim and 100% of local ZIP codes within FEMA flood zones. At that level, the risk pathways connecting flooding to water quality — treatment system stress, well infiltration, distribution backflow — become relevant considerations during significant flood events, even if day-to-day water quality is unaffected by flood history.
Sedan has a moderate flood history with 1 FEMA claims averaging $439 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.
