How Old Is Marissa's Housing Stock?
With 78% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Marissa's median build year of 1966 places it squarely in that category.
Over half of homes in Marissa were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Marissa: Remediation Cost in Perspective
Because property values in Marissa comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Marissa are relatively low compared to home values. The $300–$1,600 estimated range is a small fraction of median property value. Home values are 35% below the Illinois average.
Protecting Children from Lead in Marissa
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 78% pre-rule share in Marissa keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
