Hydrogeologic data for the McKay Creek subsurface waste-injection test site, Pinellas County, Florida
John D. Hickey
1977, Open-File Report 77-802
Lithologic, hydraulic, geophysical, and water-quality data collected at the McKay Creek subsurface waste-injection test site in Pinellas County, Florida, are reported. Data were collected to determine the possibility of subsurface injection of waste-treatment plant effluent. One exploratory hole, one test injection well, and eight observation wells were constructed between May...
Artificial recharge to a freshwater-sensitive brackish-water sand aquifer, Norfolk, Virginia
Donald L. Brown, William Dudley Silvey
1977, Professional Paper 939
Fresh water was injected into a brackish-water sand for storage and retrieval. The initial injection rate of 400 gpm decreased to 70 gpm during test 3. The specific capacity of the well decreased also, from 15.4 to 0.93 gpm. Current-meter surveys indicated uniform reduction in hydraulic conductivity of all contributing...
Geology of the Monterey Bay region
H. Gary Greene
1977, Open-File Report 77-718
Geophysical data and sea floor samples collected from the continental shelf and slope between Ano Nuevo Point and Point Sur, California indicate that the Monterey Bay region has had a complex late Cenozoic tectonic history. Uplift and depression have produced a succession of regressive and transgressive sedimentary units, while contemporaneous...

Background studies for appraising subsidence in the Texas Gulf Coast region
B. E. Lofgren
1977, Open-File Report 77-412
Significant ground movement has accompanied the extraction of large quantities of fluids from the subsurface at many localities. The possibility of both horizontal and vertical ground movement--subsidence, fissuring, growth faulting--in the Gulf Coast region, caused by the withdrawal of large volumes of deep formation fluids, is of major concern.Although widespread...

Documentation for subroutine REDUC3, an algorithm for the linear filtering of gridded magnetic data
Richard J. Blakely
1977, Open-File Report 77-784
Subroutine REDUC3 transforms a total field anomaly h1(x,y) , measured on a horizontal and rectangular grid, into a new anomaly h2(x,y). This new anomaly is produced by the same source as h1(x,y) , but (1) is observed at a different elevation, (2) has a source with a different direction of...
Water consumption by nuclear powerplants and some hydrological implications
Ennio V. Giusti, E.L. Meyer
1977, Circular 745
Published data show that estimated water consumption varies with the cooling system adopted, being least in once-through cooling (about 18 cubic feet per second per 1,000 megawatts electrical) and greatest in closed cooling with mechanical draft towers (about 30 cubic feet per second per 1,000 megawatts electrical). When freshwater is...
