waterverge.com Rocky Mount, NC — Water Quality Report
Rocky Mount's drinking water received a grade of C (60.8 out of 100), indicating fair water quality. The city's 2 water systems serve approximately 56,080 residents using surface water.
Lead levels were measured at 18.0 ppb (90th percentile), which exceeds the EPA action level of 15 ppb. UCMR 5 testing detected 2 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 79 violations on record, including 17 health-based violations. 11 remain unresolved.
What to know about Rocky Mount's water
Rocky Mount ranks #282 out of 417 cities in North Carolina 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.
Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.
Hexavalent chromium (chromium-6) was detected at 0.19 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.
Lead levels exceed the EPA action level of 15 ppb, which typically indicates aging lead service lines or lead solder in the distribution system. An NSF 53-certified filter is strongly recommended for drinking and cooking water.
The system has seen 9 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Where does Rocky Mount's water come from?
Rocky Mount's drinking water comes from surface water (rivers, lakes, or reservoirs), supplied by 2 water systems serving approximately 56,080 people. Surface water sources are more susceptible to contamination from runoff, industrial discharge, and algal blooms, requiring extensive treatment. Nearby water bodies include Tar River Below Dam (river), Tar River (river).
What Rocky Mount residents can do
Recommended: Reverse osmosis system. This addresses the specific contaminants found in Rocky Mount's water.
Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.
Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.
Rocky Mount's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.
