Public Water Supply Program 


Montana's 2016 Annual Public Water System Compliance Report

Lab Application Sample Results (LASR)

  • The Lab Application Sample Results (LASR) system is an application developed by the Montana Department of Environmental Quality to assist water testing labs with submission of public water test sample results to the Public Water Supply Compliance Program. Submission of the results is done through the EPA's Lab to State software and from there into Safe Drinking Water Information System (SDWIS)

Montana Drinking Water Watch

  • Montana Drinking Water Watch has replaced the PWS Online Query Reports.
  • Samples are now reported as microbial versus chemical so TCR and Ground Water Rule Samples are presented together, rather than as TCR versus non-TCR. You will also find additional options to search for samples across multiple water systems.


Montana Monitoring Schedule Reports

  •  Montana Monitoring Schedule Reports is used to inform PWS System personnel what they must sample for, the required number of samples to be taken, where and when samples are to be taken, sample bottle information, and whether your system has met the current requirements. It is real-time, meaning the information presented is current in the database as of the time the request is made.
