Analysis

What to know about Danville's water

Danville ranks #343 out of 345 cities in Arkansas 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.

While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection.

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

The system has seen 23 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
