The Problem with Phosphorus

Phosphorus enrichment of waterbodies negatively impacts water quality. The accumulation and internal recycling of phosphorus in waterbodies has significant and lasting impacts on the aquatic ecosystem, drinking water supplies and recreational uses. In addition, excessive phosphorus levels can result in regulatory implications due to exceeding of total maximum daily load (TMDL) thresholds and state and/or federal water quality standards.

Watershed Management Isn’t Enough

Proactive waterhshed assessment and management actions are an important best management practices to reduce the level of phosphorus entering waterbodies. Even when external sources of phosphorus have been curtailed by watershed management practices, the internal recycling of phosphorus in waterbodies can continue to degrade water quality and have lasting impacts on the aquatic ecosystem. 'In-Lake' phosphours mitagation is a critical componet of an integrated approach to restore impared water bodies.

Always read and follow label directions.
