Royalton's drinking water received a grade of C- (58.8 out of 100), indicating poor water quality. The city's 2 water systems serve approximately 1,500 residents using surface water.

Lead levels were measured at 6.5 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 177 violations on record, including 19 health-based violations. 14 remain unresolved.

Royalton ranks #75 out of 90 cities in Vermont 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, Royalton may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 11 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
