Housing Age Profile

Over half of homes in Marshall 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 Marshall Homeowners
Within the Marshall market, estimated remediation claims a small portion of typical property equity - the financial burden is proportionally low.
Remediation costs in Marshall are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 22% above the Wisconsin average.
Lead Exposure Risk for Children in Marshall
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 59% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Marshall.

Historical NFIP Claim Context in Marshall
Historical NFIP data for Marshall contains 2 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $8,485. 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.
