Geology of an area near Brentwood, Williamson County, Tennessee
D. W. Hanchar
1988, Water-Resources Investigations Report 88-4176
The geology and structure of an area near Brentwood, Williamson County, Tennessee, were studied to define the potential aquifers and confining units that comprise the groundwater flow system of the area. Four different formations were identified. These formations are, in descending order, the Bigby-Cannon Limestone, the Hermitage Formation, the Carters...
Channel infiltration from floodflows along the Pawnee River and its tributaries, west-central Kansas
James B. Gillespie, C. A. Perry
1988, Water-Resources Investigations Report 88-4055
Most of the streams is west-central Kansas are ephemeral. Natural recharge to the alluvial aquifers underlying these streams occurs during periods of storm runoff in the ephemeral channels. Proposed flood-retarding structures within the basin will alter the downstream runoff characteristics in these channels by reducing the peak flow and increasing...
Ground-water quality in the Lompoc Plain, Santa Barbara County, California, 1983
Charles Berenbrock
1988, Water-Resources Investigations Report 87-4101
Groundwater is the main source of water in the Lompoc plain, California. The lower member of the younger alluvium is the main water-bearing zone. Long-term groundwater levels in most of the plain have not changed significantly since the 1940's. Groundwater quality in the plain in 1983 tended to deteriorate from...
U.S. Geological survey program on toxic waste--ground-water contamination; proceedings of the Second technical meeting, Cape Cod, Massachusetts, October 21-25, 1985
S.E. Ragone
1988, Open-File Report 86-481
This study characterizes the clay minerals in sediments associated with a plume of creosote-contaminated groundwater. The plume of contaminated groundwater near Pensacola, FL, is in shallow, permeable, Miocene to Holocene quartz sand and flows southward toward Pensacola Bay. Clay-size fractions were separated from 41 cores, chiefly split-spoon samples at 13...
Waterfowl Management Handbook
1988, Fish and Wildlife Leaflet 13
The North American Waterfowl Management Plan, the Service's most recent mandate for management of migratory waterfowl, and recent legislation such as the Farm Bill all underscore the need for a single source of information about the management of waterfowl and their habitat. Much of this information exists in scientific papers,...
Seismicity map of the state of Texas
B.G. Reagor, C. W. Stover, S. T. Algermissen
1988, Miscellaneous Field Studies Map 2034
This map is one of a series of seismicity maps produced by the U.S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000.  This map shows only those earthquakes with epicenters located within the boundaries of Texas, even though earthquakes in...
