How Old Is Wheaton's Housing Stock?
With 73% 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
The character of Wheaton's housing stock is one of deep historical layering - a median build year of 1967 signals a city built largely before the plumbing era changes of 1986 and 1970. Lead-soldered copper joints and, in the oldest properties, lead service lines are commonly present in this inventory. That context shapes what individual water testing may reveal, particularly in neighborhoods where the oldest housing is concentrated.
Over half of homes in Wheaton were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Wheaton: Remediation Cost in Perspective
Across Wheaton, the equity share taken up by estimated remediation is small - a favorable ratio for most property owners.
Remediation costs in Wheaton are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 154% above the Illinois average.
Protecting Children from Lead in Wheaton
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Wheaton have approached or crossed the regulatory action level on multiple occasions. Combined with 73% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

Historical Flood-Claim Evidence for Wheaton
Historical NFIP data for Wheaton contains 232 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $7,574. Among ZIP codes with claim records, 50% 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.
