The transport of phosphorus from soils to surface waters can cause nutrient enrichment resulting in algal blooms and excessive aquatic plant growth. Algae can impact recreational use and cause taste and odor problems in drinking water. Once the algae and other aquatic plants die, a decomposition process begins to take place by oxygen consuming bacteria. This process can lower dissolved oxygen levels within the water potentially impacting aquatic life including fish populations. Phosphorus is considered the limiting nutrient because its absence limits the growth of algae and aquatic plants.
