Pesticide amounts are small in streams in the Red River of the North Basin, 1993-94 Pesticide amounts are small in streams in the Red River of the North Basin, 1993-94
Pesticides are used extensively in the largely agricultural Red River of the North (Red River) Basin, but, unlike many other agricultural basins, only small amounts are routinely detected in samples from streams in the basin. The pesticides detected comprise less than 2 percent of the amount applied and usually are at concentrations far less than established drinking water standards...

Pesticides detected in surface waters and fish of the Red River of the North drainage basin Pesticides detected in surface waters and fish of the Red River of the North drainage basin
The Red River of the North drainage basin (herein referred to as Red River Basin) within the United States is a study unit under the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) program. The overall goals of this program, initiated to better define the status and trends of the Nation’s water quality, are to address regional and national water-quality issues in...

Increasing rates of atmospheric mercury deposition in midcontinental North America Increasing rates of atmospheric mercury deposition in midcontinental North America
Mercury contamination of remote lakes has been attributed to increasing deposition of atmospheric mercury, yet historic deposition rates and inputs from terrestrial sources are essentially unknown. Sediments of seven headwater lakes in Minnesota and Wisconsin were used to reconstruct regional modern and preindustrial deposition rates of mercury. Whole-basin mercury fluxes, determined...
