Housing & Infrastructure in Tomah
With 56% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Renovation history matters as much as age: in Tomah, with a median build year of 1988, some older homes have been replumbed and some have not.
Over half of homes in Tomah were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Tomah Homeowners
Because the median home value in Tomah is large relative to the estimated cost of remediation, the ratio between them stays at or below 1%; that is a statement about two area-level numbers, not a quote for a particular house or a judgment about what an owner can pay.
Estimated remediation costs in Tomah can be compared with local home values. The $450–$1,400 estimated range can be set against the median property value; actual costs vary by home. Home values are 19% below the Wisconsin average.
Lead Exposure Risk for Children in Tomah
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Historical NFIP Claim Context in Tomah
Historical NFIP data for Tomah contains 32 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $3,759. 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 $800 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.
