What is Nutrient Pollution?
Nutrients, like nitrogen and phosphorus, are naturally occurring – but can be too much of a good thing when found in high concentrations in our waterways. These nutrients are very high in sewage, septic tanks, storm-water runoff, and fertilizers.
Nutrient pollution can contribute to algae blooms. Algae blooms turn the water green and smell terrible, smothering seagrass and killing fish -- they can even be harmful to humans.
Potential Sources of Nutrient Pollution
Fertilizer is often over-used in residential landscaping. Biscayne Bay and our canals are extremely sensitive to excess nutrients, so we have to be sure to keep these nutrients out of the water to avoid algae blooms.
When not properly cared for, septic tanks can leak or flood – creating a land-based source of pollution that drains into our waterways. This pollution can also contaminate the aquifer, our drinking water stored underground. Always maintain your septic tank and have it regularly inspected.
Storm-water Runoff is any type of water that doesn’t soak into the ground, but instead “runs off” down a drain or grate and into a waterway. Sometimes this water flows over polluted areas such as parking lots, roads, industrial sites, or yards, bringing contamination into waterways.
