How can eutrophication be fixed




















It is nearly impossible to turn a eutrophic lake back into an oligotrophic lake, but it is possible to turn back eutrophication somewhat. Since phosphorus is the main cause of eutrophication in most Minnesota lakes, reducing phosphorus addition to the lake is the most effective way to slow eutrophication.

Phosphorus can enter a lake through poorly managed or failing septic systems, phosphorus detergents, phosphorus lawn fertilizers, agriculture, and animal feedlots. To locate the source of eutrophication for a specific lake, complete a ground truthing study and a lakeshore inventory. High levels of nitrogen and phosphorus can cause eutrophication of water bodies. Excess nutrients can cause harmful algal blooms HABs in freshwater systems, which not only disrupt wildlife but can also produce toxins harmful to humans.

Fertilized soils, as well as livestock operations, are also vulnerable to nutrient losses to the air. Nitrogen can be lost from farm fields in the form of gaseous, nitrogen-based compounds, like ammonia and nitrogen oxides.

Ammonia can be harmful to aquatic life if large amounts are deposited from the atmosphere to surface waters. Effects The disturbance of aquatic equilibria may be more or less evident according to the enrichment of water by nutrients phosphorus and nitrogen.
