Borehole Geophysics: Tools to Characterize Rock Properties
Effective design and construction in rock requires characterization of the engineering properties of the rock mass, as well as any associated geological features such as joints, faults, and bedding planes....

Geotechnical Aspects of Pavements: There's More to Roads than Asphalt and Concrete!
When you jump on the highway to make that commute to work, do you think much about what's under the surface you ride on? Pavements are layered systems designed to provide a strong structure to support...

Permits, Surface Water/Groundwater Baseline Sampling, and Analysis of Dewey-Burdock In Situ Uranium Project in Fall River County, South Dakota
Powertech Uranium Corporation has proposed to conduct in situ mining within a uranium enriched ore deposit on the proposed permit area known as the Dewey-Burdock project. The project is...

Considerations Regarding Geochemical Transformations Downstream of Subsurface Wastewater Effluent Disposal Facilities
Many suburban and rural communities use subsurface disposal in conjunction with on-site and other small decentralized systems. In addition, to reduce the impacts of wastewater treatment...

Watershed Modeling for Surface-Groundwater Interaction
Groundwater use has increased rapidly due to irrigation development in the Great Plains. This is especially true in the Republican Basin that intersects the three states of Nebraska, Kansas...

Concentrated Animal Feeding Operations (CAFOs) and Nitrogen Conversions in the Groundwater Environment
EPA's regulatory focus on concentrated animal feeding operations has historically concentrated on potential surface water impacts from direct discharges as well as nutrient-laden runoff....

Characterization of Interaction of Surface Water and Groundwater in the El Paso Lower Valley of Texas
El Paso is located in the Chihuahua desert and prone to long periods of extreme drought. With the river drought, regional irrigation districts only received 34% and 38%of a full water...

Hydrochemical Modeling of Water Quality in a Ground and Surface Water System within a Semi-Urban Watershed

Exploring All Options
To relieve environmental stress around the Tampa Bay area's existing groundwater wells, Tampa Bay Water—the regional water supplier—is implementing a Master Water Plan that...

Coming to the Surface
In the past few years, the coastal areas of the Gulf of Mexico and much of Texas have experienced less than normal rainfall and record water demands. During this period, average daily...

National Water Quality Assessment: Moving from Measurement to Understanding
The USGS National Water Quality Assessment (NAWQA) program began in 1991. The objectives of the program were to characterize the quality of the Nations ground and surface water, assess...

Surface Irrigation
Surface irrigation refers to a large group of irrigation methods in which water is distributed by gravity over the surface of the field. Water is typically introduced at the high point...
