Nitrogen is essential for plant growth, but excessive amounts in water supplies can
result in nutrient pollution. Nitrates may enter the water from leaves or debris but
other sources of nitrates include well water supplies, localized spraying of lawn
or crop fertilizers, acid rain, bird droppings and bather wastes, urine and sweat.
Nitrates, in conjunction with phosphate, stimulate the growth of algae creating water
quality problems. Pools that are properly maintained usually do not have unexpected
diffi culty controlling algae, even in the presence of low levels of nitrates. Higher
levels of nitrates can make algae control more diffi cult and increase the amount of
chlorine required to maintain satisfactory control of algae. The only practical way to
remove nitrates is to drain the water. Nitrates also cause problems in drinking water.
Large amounts can cause “blue baby syndrome” (methemoglobenemia) in infants in
less than 6 months of age and other health problems.
