MOLE LAKE Water System

Current status

1 item on record is open and awaiting resolution as of July 4, 2026. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings. Full details are in the violation history below.

This system's next federally required Consumer Confidence Report is due July 1, 2027, under the EPA's revised reporting rule.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed July 4, 2026. This is a record-keeping and public-information tool — it does not replace EPA Region 5’s official records. Always confirm current status with EPA Region 5 before making decisions based on this information.
