Should You Be Concerned About SUPERIOR MATERIALS PLANT 23?
SUPERIOR MATERIALS PLANT 23is registered in the EPA's Toxic Release Inventory (TRI). This means the facility reports handling, releasing, or transferring toxic chemicals as part of its operations. The area's environmental safety score is 65/100 — moderate, suggesting some cumulative environmental burden from industrial activity in the area.

Health Considerations for Residents Near SUPERIOR MATERIALS PLANT 23
Living near a Toxic Release Inventory (TRI) facility in LAPEER, Michigan (48446) means potential exposure to industrial pollutants through air, water, and soil. While not every facility creates immediate health risks, long-term proximity warrants awareness and proactive steps.
Water Testing
Even with acceptable municipal water scores, homes near industrial sites should test annually for contaminants that may leach through groundwater. This is especially important for homes built before 1990 or those on well water in the 48446 area. Testing kits are available through your county health department or certified labs.
Air Quality Monitoring
Air quality in this area scores 22/100 — below average. Monitor daily AQI (Air Quality Index) at airnow.gov, particularly on hot, stagnant days when ground-level pollutants concentrate. If you notice unusual odors or visible emissions from SUPERIOR MATERIALS PLANT 23, report them to Michigan's environmental agency.
When to Consult a Doctor
Speak with your physician if you experience persistent respiratory symptoms (chronic cough, wheezing, shortness of breath), unexplained headaches, skin irritation, or unusual fatigue — particularly if these worsen when you're at home. Mention your proximity to a TRI facility so they can order appropriate screening. Vulnerable populations — children, elderly, pregnant women, and those with asthma — should be especially vigilant.
