Housing & Infrastructure in Ellsworth
With 63% 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
What does a median build year of 1973 mean for water safety in Ellsworth? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used — making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Ellsworth were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Ellsworth Homeowners
Across the Ellsworth housing market, the estimated remediation share lands in a middle tier — not a minor footnote, but not a prohibitive burden either; the cost-to-value ratio reflects a moderate equity commitment, one that sits above routine maintenance territory and warrants a dedicated line in the household budget.
Remediation costs are moderate relative to home values in Ellsworth. The estimated $2,050–$4,700 range is manageable for most homeowners but still worth budgeting for. Home values are 20% above the Wisconsin average.
Lead Exposure Risk for Children in Ellsworth
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.
If 63% of the Ellsworth inventory comes from before the federal ban on lead-bearing solder — and if utility samples sit at or near 0.015 mg/L — the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

Flood & Climate Risk in Ellsworth
FEMA data shows 100% of Ellsworth's ZIP codes mapped into designated flood zones, paired with an NFIP record of 4 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Ellsworth has a moderate flood history with 4 FEMA claims averaging $850 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>$3,200</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 Ellsworth
- 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 Ellsworth's water.
- Check your home's plumbing. With 63% of homes built before 1986, lead solder is a real possibility.
