Phosphorus is an important nutrient for aquatic plants. The amount found in
water is generally not more than 0.1 ppm unless the water has become polluted
from waste water sources or excessive drainage from agricultural areas. When
phosphorus is present in excess of the concentrations required for normal aquatic
plant growth, a process called eutrophication takes place. This creates a favorable
environment for the increase in algae and weeds. When algae cells die, oxygen is
used in the decomposition and fi sh kills often result. Rapid decomposition of dense
algae scums with associated organisms give rise to foul odors and hydrogen
sulfi de gas.
