How Old Is Joliet's Housing Stock?
With 62% 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
Reading the housing age data for Joliet - median build year 1971 - the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints - a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Joliet were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Joliet: Remediation Cost in Perspective
In Joliet, property values comfortably outpace what documented remediation typically costs - the equity share is proportionally low.
Remediation costs in Joliet 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 10% above the Montana average.
Protecting Children from Lead in Joliet
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 62% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Joliet.

Historical Flood-Claim Evidence for Joliet
Historical NFIP data for Joliet contains 12 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $15,983. 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>$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.
