Housing & Infrastructure in Mount Pleasant
With 75% 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
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. Mount Pleasant's median build year of 1945 places it squarely in that category.
Over half of homes in Mount Pleasant 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 Mount Pleasant Homeowners
Equity impact data for Mount Pleasant lands in the favorable tier — remediation claims a small slice of what properties here are worth.
Remediation costs in Mount Pleasant are relatively low compared to home values. The $517–$1,467 estimated range is a small fraction of median property value. Home values are 18% below the Michigan average.
Lead Exposure Risk for Children in Mount Pleasant
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted — but 75% of the Mount Pleasant inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.

Flood & Climate Risk in Mount Pleasant
Measured across the NFIP's multi-decade tracking period, Mount Pleasant shows a moderate flood record — 22 claims and 33% of ZIP codes carrying FEMA flood zone status. For water quality, that combination matters because flood events at this frequency can periodically stress infrastructure: treatment plants, private wells, and distribution systems all face elevated risk during significant flooding.
Mount Pleasant has a moderate flood history with 22 FEMA claims averaging $19,806 per payout. 33% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$867</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
