A nationwide study of nitrate trends in the ground water of the United States was recently completed by scientists at the US Geological Survey. Nitrate is the most common chemical contaminant found in ground water, and is related to infant health and possible cancer risks. The study focused on 24 well networks in the US from 1988 to 2004, of which seven well networks showed statistically significant increases in concentrations of nitrate during this period.
