Leaves are rich in nutrients including phosphorus, nitrogen, and potassium. When leaves are left on top of storm drains, these nutrients leach out into stormwater runoff, creating โphosphorus teaโ. Storm drains then transport the nutrient heavy water directly into our rivers and lakes, often causing unwanted algae blooms that harm aquatic ecosystems and interfere with outdoor recreational activities. Stop brewing phosphorus tea by keeping storm drains clear of leaves this fall.
