Analysis

What to know about Mt Pleasant's water

Mt Pleasant ranks #345 out of 417 cities in North Carolina for water quality, placing it among the lowest-rated 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.

Haloacetic acid (HAA5) levels were elevated at 52.1 µg/L in UCMR 4 testing, though below the 60 µg/L EPA limit. Activated carbon filtration can help reduce these disinfection byproducts.
