Water Quality

Protecting our valuable water resources is imperative. Private, public and recreational waters all have different guidelines and regulations and it’s important to know the difference.

A private water supply provides water for human consumption, serving less than 15 connections and less than 25 people regularly (at least 60 days per year). It is the responsibility of the water supply owner and user to ensure it is safe.

A Public Water Supply (PWS) is defined as water systems serving 15 or more connections or 25 or more persons daily for 60 or more days in a calendar year. The Montana Department of Environmental Quality (MDEQ) Public Water Supply Program is responsible for assuring that the public health is maintained through a safe and adequate supply of drinking water. This function is achieved by technical review, licensing, certifications, compliance monitoring, training and technical assistance.

Waterborne diseases are usually spread through contaminated water, and most diseases cause intestinal distress, such as diarrhea and vomiting, and some cases can result in death.
