The Public Works Department staffs a State Certified Laboratory responsible for testing and monitoring the water quality. Testing is performed throughout the entire treatment processes, as well as testing while in the distribution system. We perform many hundreds of tests and analysis monthly to ensure that we deliver a superior quality product for your drinking water.


Each month, we submit a detailed report to the Montana Department of Environmental Quality documenting our compliance with all applicable regulations. We publish a monthly water quality report for the Yellowstone River, which is our water source, and for our finished drinking water product.
