Explains the effects of the interaction of hydrologic and biological processes on agricultural chemicals in various environments.
PDF Acid rain effects on Adirondack streams - results from the 2003-05 western Adirondack stream survey (the WASS Project) [More info]
Acidified soils caused toxic aluminum in 66 percent of 565 assessed streams. Diatoms and aquatic macroinvertebrates were moderately to severely affected. These effects have not improved in areas surveyed in the early 1980s
PDF Characterization of Fish Creek, Teton County, Wyoming, 2004-08 [More info]
Preliminary results of hydrologic and biological sampling confirm anecdotal reports that this stream shows unusually high algal growth due to elevated nutrients, probably from groundwater.
PDF Chloride control and monitoring program in the Wichita River Basin, Texas, 1996-2009 [More info]
Chloride concentrations in this river have historically been high due to natural saltwater springs and seeps from geologic formations. We monitor the water to help assess the progress of human efforts designed to mitigate this problematic salinity.
PDF Condition of streams in Independence, Missouri: What is being done to protect stream health and how citizens can help [More info]
Stream water quality is affected by amount of impermeable surface in the basin; construction; reservoirs; sanitary sewer systems; land use and population density; road salt; animal waste; lawn and agricultural fertilizers, pesticides, and herbicides.
