Abstract
The U.S. Geological Survey has studied the ground-water quality within two
areas of the Red River of the North (Red River) Basin in southeastern North Dakota and
west-central Minnesota. Although both areas are underlain by sandy surficial
aquifers over which intensive irrigated agriculture dominates the land use,
their ground-water quality differs. Ground water from the eastern study area
has significantly higher concentrations of nitrate and agricultural herbicides
than does ground water from the western area. Major differences in rainfall
and minor differences in soils, depth to ground water, and agricultural
practices between these two areas can account for the differences measured in
ground-water quality. These same factors may indicate changes in ground-water quality from agricultural land uses in other surficial aquifers in the
Red River of the North Basin.
