Federal record
U.S. EPA's Safe Drinking Water Information System lists 136 violations for this system across its recorded history, of which 90 are health-based. An honest word before that number alarms anyone: most violations at small volunteer-run systems are paperwork — a sample not taken on schedule, a report filed late — not unsafe water. The health-based column is the one to read closely.
