Welcome to the Montana Nonpoint Source Management Program web site. Our goal is to protect and restore water quality from the impacts of nonpoint sources of pollution in order to provide a clean and healthy environment.

Nonpoint Source (NPS) pollution, unlike pollution from industrial and sewage treatment plants (point sources), comes from many widespread sources and can be generated by most land use activities including agriculture, forestry, urban and suburban development, and others. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters, and even our underground sources of drinking water. Common NPS pollutants include sediment, nutrients, heavy metals, pesticides, pathogens, pharmaceuticals, oil, and salt.
