Water Quality Snapshot: MONTGOMERY COUNTY WATER SYSTEM

MONTGOMERY COUNTY WATER SYSTEM is a local-owned community water system that delivers drinking water to 14,710 residents in MT GILEAD, North Carolina (Montgomery County) through 5,884 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 235 total violations for this system , of which 74 (31%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 121 monitoring and reporting violations are on file. The most recent violation on record dates to 2025.

The most frequently cited contaminant at this system is Total Haloacetic Acids (HAA5), recorded in 26 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 2 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 0.0044 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across North Carolina, EPA tracks 5,020 public water systems serving 9,877,724 people, with 524,053 cumulative violations and 38,492 health-based violations on record. About 93% of systems in the state carry at least one violation, and state-wide the average per system is 104.4 violations. MONTGOMERY COUNTY WATER SYSTEM's 235 violations sit above the North Carolina average. Statewide, 174 of 287 UCMR5-tested systems have reported PFAS detections (60.6%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
