Nitrates in groundwater

Nitrite (or compounds at the same or lower oxidation level) is produced microbiologically from nitrate, and may then react with the substrate to produce stable end products. The production of nitrite is the sole metabolic function of the bacteria and, in view of concern over the presence of nitrate in groundwater, the following possible environmental significance of these or analogous reactions should not be overlooked ... [Pg.55]

Nitrates and nitrites are present in all tap and bottled waters. They are produced by erosion of natural deposits and during the natural decay of vegetable material in soil. Rainfall washes these salts from the sub-soil into groundwater. Nitrogenous fertihsers used on arable farmland and leaks from septic tanks can be significant sources of nitrates in groundwater and surface water. [Pg.465]
