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 fish kills often result. Rapid
decomposition of dense algae scums with associated organisms give rise to foul
odors and hydrogen sulfide gas.
