Effects of the Paradox Valley Unit on dissolved solids, sodium, and chloride in the Dolores River near Bedrock, Colorado, water years 1988-98
During 1999, a study was conducted by the U.S. Geological Survey (USGS) in cooperation with the Bureau of Reclamation to evaluate the effect of the Paradox Valley Unit on dissolved solids, sodium, and chloride in the Dolores River downstream from the Paradox Valley Unit. This report describes this evaluation and presents the results from this study. Daily mean flow and daily mean specific conducta

Finding minimal herbicide concentrations in ground water? Try looking for their degradates
Extensive research has been conducted regarding the occurrence of herbicides in the hydrologic system, their fate, and their effects on human health and the environment. Few studies, however, have considered herbicide transformation products (degradates). In this study of Iowa ground water, herbicide degradates were frequently detected. In fact, herbicide degradates were eight of the 10 most frequ

Metal exposure in a benthic macroinvertebrate, Hydropsyche californica, related to mine drainage in the Sacramento River
A biomonitoring technique was employed to complement studies of metal transport in the upper Sacramento River affected by acid mine drainage. Metals (Al, Cd, Cu, Fe, Hg, Pb, and Zn) were determined in a resident invertebrate, Hydropsyche californica (Insecta: Trichoptera), and streambed sediments (<62 µm) to assess metal contamination within a 111-km section of the river downstream of the mining a

Progress of environmental studies in coal mining areas of western Pennsylvania and central West Virginia
Two studies related to the regional environmental effects of coal mining in the Appalachian Plateau were conducted in 1998 as part of the National Water‐Quality Assessment program of the U.S. Geological Survey. The study area of about 20,000 square miles included parts of the Allegheny and Monongahela River basins in the north and the Kanawha River basin in the south. Water in domestic wells downg

Evaluation of factors that influence estimated zones of transport for six municipal wells in Clark County, Washington
A ground-water flow model was used in conjunction with particle tracking to estimate zones of transport for six municipal well sites in Clark County, Washington. A zone of transport for a well is a three-dimensional volume within a ground-water system that contains all of the ground water that will discharge from that well within a specified time period. All of the zones of transport for a well co

Mississippi Basin Carbon Project; upland soil database for sites in Yazoo Basin, northern Mississippi
The conversion of land from its native state to an agricultural use commonly results in a significant loss of soil carbon (Mann, 1985; Davidson and Ackerman, 1993). Globally, this loss is estimated to account for as much as 1/3 of the net CO2 emissions for the period of 1850 to 1980 (Houghton et al, 1983). Roughly 20 to 40 percent of original soil carbon is estimated to be lost as CO2 as a result
