How Old Is Trevor's Housing Stock?
With 46% 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
Development in Trevor unfolded across multiple decades, and the median build year of 1999 reflects a housing inventory where eras of construction are genuinely mixed — including portions that predate the federal prohibition on lead solder in plumbing.
Most homes in Trevor were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Trevor: Remediation Cost in Perspective
When estimated remediation is placed alongside median property values in Trevor, the resulting ratio is low — a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Trevor are relatively low compared to home values. The $950–$3,200 estimated range is a small fraction of median property value. Home values are 15% above the Wisconsin average.
Protecting Children from Lead in Trevor
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 utility-side compliance with federal Lead and Copper requirements remains the system reference, that compliance does not extend down into interior plumbing. With 46% of Trevor stock built before the solder ban and aggregate readings at or beyond the action mark, a household-level sample becomes the practical way to close that information gap.

Climate-Related Water Risk for Trevor
Trevor's flood exposure sits in the moderate range: 70 NFIP claims on record and 100% of ZIP codes within FEMA-designated flood zones. Residents with private wells or older infrastructure have reasonable grounds to factor flood timing into their water quality awareness.
Trevor has a moderate flood history with 70 FEMA claims averaging $13,744 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>$1,900</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.
