Water Quality District

The Missoula Valley Water Quality District works to protect Missoula’s sole-source aquifer.

The water that we drink comes from the aquifer that we live and work on top of. To maintain high quality drinking water, the District conducts water quality studies, maintains a network of monitoring wells, and ensures spills are cleaned-up.

The Missoula Valley Water Quality District was formed in 1993 to protect Missoula Valley’s EPA designated sole-source aquifer, surface and groundwater.

What we do:
  • Annual monitoring of 44 dedicated monitoring wells and the 6 major streams within the district.
  • Monitoring and water quality research to assess and prioritize water quality issues.
  • Inspections of businesses that maintain quantities and types of hazardous materials that could contaminate or impact soil or water resources.
  • Enforcement of state water quality laws and local ordinances.
  • Public education on prevention of water pollution.
  • Local review of state and federal cleanup sites.
  • Maintaining a public health laboratory for water research and contaminant investigation
