Phosphorus is an essential element for plant life, but when there is too much of it in water, it causes a condition called eutrophication. A sign of eutrophication is excess algae in lakes and rivers. Excessive algae reduces oxygen in the water for fish and can be toxic to humans. Control the release of phosphorus by:
- Reducing the applications of lawn fertilizers
- Disposal of pet wastes
- Reduce laundry and dish washing detergent
- Wash your vehicle on your lawn or at a commercial car wash
- Look for product labels that do not include phosphorus or phosphates
