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
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.
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.
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.
Dissolved solids in basin-fill aquifers and streams in the southwestern United States [More info]
Evaluation of Structural Best Management Practices for Highway Runoff in Beaufort and Colleton Counties, South Carolina, 2005-2006 [More info]: Summarizes the ability of four devices to remove suspended sediment, metals, nutrients, and organics compounds in stormwater runoff.
Evaluation of fecal contamination by human and ruminant sources in upper Fountain Creek, Colorado, 2007-2008, by using multiple lines of evidence: [More info]: Microbial source tracking analysis of water sampled supports the argument that birds are the primary source of fecal contamination during the warm season.
Hydrology of Johnson Creek Basin, a Mixed-Use Drainage Basin in the Portland, Oregon, Metropolitan Area [More info]: Study of a small stream that has had a history of persistent flooding and water-quality problems.
Identifying sources of fecal coliform bacteria in selected streams on Virginia's Total Maximum Daily Loads (TMDL) priority list [More info]: Describes project to identify sources of fecal coliform bacteria by ribotyping to develop the use of Maximum Daily Load (TMDL) values for contaminated stream segments in Virginia.
Johnson Creek basin hydrologic monitoring [More info]: Hydrologic data and analyses of surface-water, water quality, and ground water in the Johnson Creek basin in Oregon.
