How Old Is Chadwick's Housing Stock?
With 92% 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 median home in Chadwick was built in 1900 — a figure that places most of the city's residential stock in the era when lead solder was still standard in copper plumbing. Homes built before 1986 may have lead-soldered joints; those built before 1970 face the additional possibility of lead pipes in the service line itself.
Over half of homes in Chadwick were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Chadwick: Remediation Cost in Perspective
Viewed from a financial planning lens, Chadwick sits in the moderate remediation-share tier — the equity impact of addressing documented issues is real, and deliberate preparation separates smooth outcomes from disruptive ones for most homeowners.
Remediation costs are moderate relative to home values in Chadwick. The estimated $950–$2,100 range is manageable for most homeowners but still worth budgeting for. Home values are 40% below the Illinois average.
Protecting Children from Lead in Chadwick
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.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 92% of Chadwick stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.
