Nutrient Pollution

Nutrients (nitrogen and phosphorus), in appropriate amounts, are essential to healthy aquatic ecosystems. Excessive nutrients, or nutrient pollution, however, can result in excessive growth of vegetation (i.e., aquatic plants and algae) that can lead to oxygen depletion, high pH, fish kills, and general degradation of aquatic resources. Drinking water supplies with excessive nutrients require costly treatment, while surface waters with nutrient pollution can impact use of the water for recreation, livestock, and wildlife.

Wyoming is addressing nutrient pollution in Wyoming’s surface waters through development of Numeric Nutrient Criteria and Wyoming Nutrient Strategy.
