Housing & Infrastructure in Irondale
With 60% 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
Federal plumbing rules changed in two stages — lead pipes were phased out before 1970, and lead solder was banned in 1986 — but in Irondale, where the median build year is 1986, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.
Over half of homes in Irondale 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 Irondale Homeowners
When estimated remediation is placed alongside median property values in Irondale, the resulting ratio is low — a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Irondale are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 47% below the Missouri average.
Lead Exposure Risk for Children in Irondale
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.
Wherever 60% of local housing was built before solder rules changed — as is the case in Irondale — a faucet-level sample closes the gap that aggregate utility data cannot.
