In detail

Nitrite is added to water in cooling towers at high concentrations to act as a corrosion inhibitor.

It is present in low concentrations in surface waters and rarely in groundwaters.

In wastewaters, nitrite concentrations are often higher.

Nitrite is produced during the bacterial oxidation of ammonia and in the reduction of nitrate.
