Potential effects of surface coal mining on the hydrology of the upper Otter Creek-Pasture Creek area, Moorhead coal field, southeastern Montana
N. E. McClymonds, J. A. Moreland
1988, Water-Resources Investigations Report 88-4187
The combined upper Otter Creek-Pasture Creek area, south of Ashland, Montana, contains large reserves of Federal coal for potential lease sale. A hydrologic study was conducted in the area to describe existing hydrologic systems and generalized groundwater quality, to assess potential effects of surface mining on local water resources, and...

The first groundwater study by the U.S. Geological Survey (USGS) in Florida began in 1910. In 1930, a cooperative program of study was started with the Florida Geological Survey, and in 1938, the first groundwater office of the USGS was established in Miami. In fiscal year 1987, the USGS program...
Relation of salinity and selenium in shallow ground water to hydrologic and geochemical processes, western San Joaquin Valley, California
S. J. Deverel, S.K. Gallanthine
1988, Open-File Report 88-336
Salinity and selenium concentrations in shallow ground water of the western San Joaquin Valley, California, are related to the geomorphology and hydrology of the alluvial fans. The highest salinity and selenium concentrations in shallow ground water occur in alluvium deposited by ephemeral streams and at the margins of the major...
Eustrongylides sp. epizootic in young common egrets (Casmerodius albus)
Thomas J. Roffe
1988, Avian Diseases (32) 143-147
In May 1985, epizootic mortality was reported in common egrets (Casmerodius albus) on Avery Island, Louisiana. Subsequent investigation revealed that more than 400 birds died. Severe peritoneal nematodiasis (Eustrongylides sp.) was found on postmortem examination. A nearby breeding rookery on the same island was apparently unaffected. Reasons for this selective...
