Likely Pipe Material

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

Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Larsen's median build year of 1974 reflects a housing stock where these older materials are a pervasive feature - not a rare legacy - of the residential plumbing landscape.

Over half of homes in Larsen 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 Larsen Homeowners

While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Larsen is notably favorable - the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.

Median Home Value
$266,700
Est. Remediation
$1,600
Remediation as % of home value 0.6%

Remediation costs in Larsen are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 16% above the Wisconsin average.

Lead Exposure Risk for Children in Larsen

63%
Homes Built Before 1986
0.0018
mg/L Avg Lead (Limit: 0.015)

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.

Even where utility-side monitoring meets Lead and Copper Rule requirements, the 63% pre-rule share in Larsen keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Larsen contains 8 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $5,112. 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>$1,600</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.
