QUESTION: Why do we worry about the phosphorus content in our septic system?ANSWER: This is another frequent question I receive. Phosphorus is the limiting nutrient for algal growth in most freshwater lakes. These blooms can lead to toxic conditions for animals that drink or come in contact with water where these blue algae blooms occur. Further, the algal blooms can use up precious oxygen that fish and other aquatic organisms need to survive. This, combined with lower light penetration due to the algae in the water, can result in the loss of aquatic vegetation and lead to fish die-offs during
