Key Contaminants Detected in Lomira
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Lomira's Housing Stock?
With 49% 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
Over the decades, Lomira accumulated housing from multiple construction periods. The median build year of 1983 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited — leaving a sizable share of homes on each side of that safety line.
Most homes in Lomira were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lomira: Remediation Cost in Perspective
Placing remediation in the context of Lomira's property market, the equity share is low — most homeowners here are weighing a financial commitment that fits comfortably within routine property planning, far from the threshold where remediation becomes a material equity decision rather than a standard upkeep consideration.
Remediation costs in Lomira are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 7% below the Wisconsin average.
Protecting Children from Lead in Lomira
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 49% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Lomira.
