Phosphorus in natural waters and wastewaters occurs almost exclusively in the
form of orthophosphates, condensed phosphates (pyro-, meta- and other
polyphosphates) and organically bound phosphates. Phosphates may be added
in small amounts to water supplies during treatment. Larger amounts are
introduced to water used for cleaning or laundering as components of
commercial cleaning preparations. Phosphates are used to treat boiler water
and are components of agricultural and residential fertilizers. Phosphorus is an
important nutrient for aquatic plants. The amount found in natural water is
