Key Contaminants Detected in De Pere
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is De Pere's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In De Pere, the median build year of 1994 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in De Pere were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
Source: U.S. Census Bureau ACS B25034.
De Pere: Remediation Cost in Perspective
Given current De Pere valuations, the remediation-to-property-value ratio is low - most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in De Pere are relatively low compared to home values. The $950–$3,200 estimated range is a small fraction of median property value. Home values are 33% above the Wisconsin average.
Protecting Children from Lead in De Pere
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.
When older housing represents 36% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual De Pere address.

Historical Flood-Claim Evidence for De Pere
Historical NFIP data for De Pere contains 9 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $7,682. Among ZIP codes with claim records, 0% 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>$1,900</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.
