Water Quality Snapshot: COTERRA ENERGY

COTERRA ENERGY is a private-owned non-transient non-community water system that delivers drinking water to 50 residents in MONTROSE, Pennsylvania (Susquehanna County) through 3 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 36 total violations for this system , of which 0 (0%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 36 monitoring and reporting violations are on file. The most recent violation on record dates to 2018.

The most frequently cited contaminant at this system is Atrazine, recorded in 4 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 17.9 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Pennsylvania, EPA tracks 7,701 public water systems serving 12,630,061 people, with 1,159,868 cumulative violations and 68,517 health-based violations on record. About 97% of systems in the state carry at least one violation, and state-wide the average per system is 150.6 violations. COTERRA ENERGY's 36 violations sit below the Pennsylvania average. Statewide, 224 of 389 UCMR5-tested systems have reported PFAS detections (57.6%).
