Analysis

What to know about Mount Clemens's water

Mount Clemens ranks #273 out of 520 cities in Michigan for water quality, placing it below average in the state.

The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection.

PFAS compounds were detected in testing, though levels remain within current EPA limits. Residents seeking extra precaution may consider an activated carbon or reverse osmosis filter.

Haloacetic acid (HAA5) levels were elevated at 32.0 µg/L in UCMR 4 testing, though below the 60 µg/L EPA limit. Activated carbon filtration can help reduce these disinfection byproducts.

Hexavalent chromium (chromium-6) was detected at 0.81 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.

The system has seen 7 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
