Winona Infrastructure Age
With 47% 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
Over the decades, Winona accumulated housing from multiple construction periods. The median build year of 1982 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited - leaving a sizable share of homes on each side of that safety line.
Most homes in Winona were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Winona
Given current Winona property values, the remediation share falls in the moderate tier - an indicator that the household financial perspective here calls for advance planning rather than dismissal, with most homeowners positioned to address documented issues through deliberate budgeting rather than needing to treat remediation as a significant equity event or financial emergency.
Remediation costs are moderate relative to home values in Winona. The estimated $1,500–$4,000 range is manageable for most homeowners but still worth budgeting for. Home values are 38% below the Texas average.
Winona: 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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 47% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Winona.

Winona: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Winona contains 2 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $86,195. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The <strong>$2,400</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
