Effects of treated municipal effluent irrigation on ground water beneath sprayfields, Tallahassee, Florida
J. B. Pruitt, J. F. Elder, I. K. Johnson
1988, Water-Resources Investigations Report 88-4092
Groundwater quality data collection began in November 1979 at a spray-irrigation site near Tallahassee, Florida, before the initial application of secondary-treated municipal wastewater in November 1980. Effects of effluent irrigation on groundwater quality were evident about 1 year after spraying began and have continued to increase during the study period...
Description and evaluation of the effects of urban and agricultural development on the surficial aquifer system, Palm Beach County, Florida
W. L. Miller
1988, Water-Resources Investigations Report 88-4056
The surficial aquifer system in Palm Beach County was studied during 1982-85 to determine the effects of increased urban and agricultural development on groundwater levels, flow directions, and quality. The surficial aquifer system and its geologic matrix are divisible into three zones on the bases of relative permeabilities and lithologic...
Geologic structure and altitude of the top of the Minnelusa Formation, northeastern Black Hills, South Dakota
Kathy D. Peter, David P. Kyllonen, Kathy R. Mills
1988, Water-Resources Investigations Report 85-4233
This map shows the altitude of the top of the Permian--and Pennsylvanian age Minnelusa Formation, the deepest aquifer in the northeastern Black Hills for which there is sufficient data available to construct a structural map. The Minnelusa Formation outcrops in the western part of the map area and is more...
Estimates of evapotranspiration in alkaline scrub and meadow communities of Owens Valley, California, using the Bowen-ratio, eddy-correlation, and Penman-combination methods
L. F. W. Duell Jr.
1988, Open-File Report 88-92
In Owens Valley, evapotranspiration (ET) is one of the largest components of outflow in the hydrologic budget and the least understood. ET estimates for December 1983 through October 1985 were made for seven representative locations selected on the basis of geohydrology and the characteristics of phreatophytic alkaline scrub and meadow...
Specific conductance; theoretical considerations and application to analytical quality control
Ronald L. Miller, Wesley L. Bradford, Norman E. Peters
1988, Water Supply Paper 2311
This report considers several theoretical aspects and practical applications of specific conductance to the study of natural waters. A review of accepted measurements of conductivity of secondary standard 0.01 N KCl solution suggests that a widely used algorithm for predicting the temperature variation in conductivity is in error. A new...
Water resources data, Maine, water year 1986
W.P. Bartlett Jr., W.B. Higgins, W.J. Nichols Jr.
1988, Water Data Report ME-86-1
Water resources data for the 1986 water year for Maine consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report contains discharge records for 48 gaging stations; stage only for 2...
