PDF Wildfire effects on source-water quality--Lessons from Fourmile Canyon fire, Colorado, and implications for drinking-water treatment [More info]
Stream discharge and nitrate concentration increased downstream of the burned area during snowmelt, but these were probably within the treatment capacity of most drinking-water plants, and limited changes were observed in downstream ecosystems.

The report describes a strategy for monitoring, modeling, and research activities to support management decisions to improve water-quality conditions in the Mississippi River Basin, reduce hypoxia in the northern Gulf of Mexico, and improve conditions for
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 Acid Rain in Shenandoah National Park, Virginia [More info]
Explains acidity and acid rain and how it affects aquatic organisms. Describes the effect of acid rain on this national park, identifying areas that are at greater or lesser risk from acid rain.
Atchafalaya & Mississippi River Deltas study: a tale of two deltas [More info]
Project of the Gulf of Mexico Integrated Science program that evaluates the transport and sedimentation of contaminates through the Mississippi River and Atchafalaya River delta to the near-shore Gulf of Mexico. Includes aerial photographs.
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.
