Accounting for cyanide and its degradation products at three Nevada gold mines; constraints from stable C- and N-isotopes
C. A. Johnson, D. J. Grimes, R. O. Rye
1998, Open-File Report 98-753
An understanding of the fate of cyanide (CN-) in mine process waters is important for addressing environmental concerns and for taking steps to minimize reagent costs. The utility of stable isotope methods in identifying cyanide loss pathways has been investigated in case studies at three Nevada gold mines. Freshly prepared barren solutions at the...
Evaluation of faults and their effect on ground-water flow southwest of Frenchman Flat, Nye and Clark counties, Nevada: a digital database
Edwin H. McKee, Thomas A. Wickham, Karen L. Wheeler
1998, Open-File Report 98-580
Ground-water flow through the region south and west of Frenchman Flat, in the Ash Meadows subbasin of the Death Valley ground-water flow system, is controlled mostly by faults which arrange the distribution of permeable and impermeable rocks. In addition, most permeability is along fractures caused by faulting in carbonate rocks....

Hydrologic and hydraulic analyses of selected streams in Erie County, Ohio
K. Scott Jackson, Chad J. Ostheimer, Matthew T. Whitehead
1998, Open-File Report 1998–0395
Hydrologic and hydraulic analyses were done for parts of Abel Ditch, Edson Creek, Maurer Ditch, and Sherod Creek1 in northeastern Vermilion Township, Erie County, Ohio. For each stream, instantaneous peak discharges for floods having recurrence intervals of 2, 5, 10, 25, 50, and 100 years were estimated using regional regression...
