Housing & Infrastructure in Dalzell
With 82% 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
Because the majority of Dalzell's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1969 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Dalzell 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 Dalzell Homeowners
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Dalzell 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.
Remediation costs in Dalzell are relatively low compared to home values. The $950–$2,100 estimated range is a small fraction of median property value. Home values are 13% below the Illinois average.
Lead Exposure Risk for Children in Dalzell
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.
Older stock in Dalzell represents 82% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
