Nutrient pollution occurs when there is too much nitrogen and phosphorus in an aquatic ecosystem. The primary sources for these nutrients include agriculture, stormwater, waste water, and home landscaping. When a water system is overloaded with too much nitrogen and phosphorus, algae will grow more quickly than the ecosystem can handle. This growth, called an algal bloom, harms the water quality.
