INTRODUCTION
Ammonia nitrogen is present in various concentrations in many surface and ground
water supplies. Any sudden change in the concentration of ammonia nitrogen in a water
supply is cause for suspicion. A product of microbiological activity, ammonia nitrogen is
sometimes accepted as chemical evidence of pollution when encountered in natural
waters.
Ammonia is rapidly oxidized in natural water systems by special bacterial groups that
produce nitrite and nitrate. This oxidation requires that dissolved oxygen be available in
the water. Ammonia is an additional source of nitrogen as a nutrient which may
contribute to the expanded growth of undesirable algae and other forms of plant growth
that overload the natural system and cause pollution.
