As temperatures rise this summer, people turn to local beaches and lakes as a fun way to cool off. However, recent toxic algal blooms have hindered this experience for some in places likeFlorida, California, New York, and Vermont. |

There’s a nutrient “problem”?
Did you know nutrient pollution, primarily in the form of too much nitrogen and phosphorus, is one of the nation’s most widespread, costly and challenging environmental problems? Some 16,000 waterways are impaired, and 78 percent of assessed coastal waters suffer from nutrient pollution, affecting water used for drinking, fishing, swimming and other recreational purposes. These impacts also threaten tourism, home and property values and public health.
Nitrogen and phosphorous are food for some plants, like algae, and too much can spark a large algal bloom that can end up consuming all the dissolved oxygen in a waterway, causing fish to be starved for that critical gasp of O2. Fish die-offs are common with extreme nutrient problems.
