Excess nutrients in waterways continue to be an issue
Excess Nutrients in Waterways (opens new browser tab) is one of America's most widespread water
quality issues. While nutrients are important, too much of a good thing can become a bad thing.
Excess nutrients can lead to excessive algae growth, which can use up oxygen that aquatic organisms , _
need to survive. Too much algae growth can cause fish to die. Learn more about what EPA is doing to
