<br /> Nitrite is not common in natural ground-water conditions,and nitrate plus nitrite is usually composed of all or mostly nitrate.Most samples in this database were analyzed for
<br /> nitrate plus nitrite rather than for just nitrate;therefore,nitrate and nitrate plus nitrite concentrations were combined for the purpose of this study and are referred to in the text
<br /> as"nitrate concentrations."
