Likely Pipe Material

With 55% 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

Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Irma's median build year of 1987 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.

Over half of homes in Irma were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Irma: Remediation Cost in Perspective

In Irma, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.

Median Home Value
$223,700
Est. Remediation

Remediation as % of home value 0.2%

Remediation costs in Irma are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 3% below the Wisconsin average.

Protecting Children from Lead in Irma

mg/L Avg Lead (Limit: 0.015)

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.

Routinely in Irma, where 55% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
