INDIANA, PA · Indiana County

ICMSA ARCADIA Water System

Current status

10 items on record are 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 Pennsylvania’s official records. Always confirm current status with Pennsylvania before making decisions based on this information.
