Analysis

What to know about East Carbon's water

East Carbon ranks #88 out of 177 cities in Utah for water quality, placing it mid-range 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 30.8 µg/L in UCMR 4 testing, though below the 60 µg/L EPA limit. Activated carbon filtration can help reduce these disinfection byproducts.

As a small community water system, East Carbon may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

The system has seen 6 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
