As of July 2026, EPA records show 36 violations across the community water system(s) serving Cobleskill, going back to the earliest EPA record. 35 of these are classified by the EPA as health-based (a contaminant recorded above the limit the EPA tracks); the rest are monitoring or reporting violations.

Health-based Surface Water Treatment Rule: a health-based violation (a contaminant recorded above the limit the EPA tracks), recorded 14 times between January 2024 and August 2024. The EPA record for these does not include a measured level. EPA records do not show all of these as returned to compliance.

Health-based TTHM: a health-based violation (a contaminant recorded above the limit the EPA tracks), recorded 14 times between July 2021 and October 2022. The EPA record lists a level of 82.6 UG/L; the limit (MCL) is 80 UG/L. EPA records do not show all of these as returned to compliance.
What this means
A health-based violation means a contaminant was recorded above the limit the EPA tracks for it. A monitoring or reporting violation means a required test or report was late or missed — not that a contaminant was measured above a limit. “Returned to compliance” means the EPA recorded the issue as resolved.
