The water system serves approximately 21 year-round residents and 29 service connections. The system is supplied by one natural hot spring via gravity that has no treatment. The State of Montana has referred this system to the EPA for failure to provide consumer public notice for lead and copper sampling, failure to monitor for synthetic organic contaminates and asbestos. The EPA issued an earlier AO in December 14, 2009 for the system to come back into compliance with the arsenic MCL and submit their Consumer Confidence Report (CCR), which was later amended to include coming back into compliance with the combined radium MCLs. The system has since violated the original order six times and the EPA is purposing escalating enforcement to penalty.
