Ground Water Recharge in Central and West Coast Basins
The agencies responsible for the Central and West Coast Basins of Los Angeles County, California have managed their ground water supplies by the artificial recharge of reclaimed and imported...
Role of Soil-Aquifer Treatment in Water Reuse
Reuse of municipal wastewater requires treatment so that the water meets the quality requirements for the intended use. Irrigation of vegetables consumed raw requires absence of pathogenic...
Plume Management for Groundwater Remediation
Site-specific data for four sites were compiled to evaluate the effectiveness of pumping and treating contaminated groundwater and recharging the treated groundwater to the surficial aquifer....
Effect on Soil and Groundwater Due to Long-Term Land Treatment
A comprehensive assessment of the environmental impact of a full-scale, operating overland flow (OLF) land treatment system was made of the Campbell Soup, Inc. OLF system in Paris, Texas....
Water, an Endangered Ecosystem; the Assessment of Chemical Pollution
The pervasive nature of water and its accessibility to mankind leaves it open to a variety of man-induced changes ranging from diversion of water flows to heavy metals pollution. The abuses...
Review of Mitigation Methods for Fish Passage, Instream Flows, and Water Quality
Current environmental mitigation practices at nonfederal hydropower projects were analyzed. Information was obtained from project operators on dissolved oxygen (DO) mitigation, instream...
Side Effect of the Cross-Flow Turbine: Improved Water Quality
The working principle of the Original Cross-Flow Turbine with draft tube demands air induced into the turbine housing to operate at high efficiency. Reoxygenation of water will occur,...
One Hydro Project?Many Regulatory Masters
A discussion of the dispersion of federal regulatory authority over the development of new hydro-power capacity is presented....
Harrisburg Hydroelectric Project?Water Quality Issues
The Harrisburg Hydroelectric Project is a proposed 34.4 MW hydroelectric facility on the Susquehanna River near Harrisburg, Pennsylvania. The project will consist of a 16.5 ft high gated...
Reviewing the Role of Hydropower in TVA Reservoir Operations
The Tennessee Valley Authority (TVA) has reviewed the long term operating priorities for its reservoir system to determine the appropriate role of water quality and recreation as compared...
The Wisconsin River System Operations Model: WIRSOM
The passage of the Electric Consumers Protection Act of 1986 requires the Federal Energy Regulatory Commission to give equal consideration to non-power as well as power values in hydroelectric...
Physical Hydraulic Modeling for Construction of New York State Dam Hydroelectric Project
The New York State Dam is located on the Mohawk River near its confluence with the Hudson River. Downstream from the dam, the river flow is divided into four main channels as the water...
Total Quality Planning
When it comes to major unit maintenance, 'total quality results' require an investment in 'total quality planning.' The successful replacement...
Deflector Plate Turbine Aeration?Case Studies
Water quality requirements have become a focal point in recent re-licensing of hydroelectric projects. The Federal Energy Regulatory Commission has significantly increased the relevance...
Water Quality Sampling Under Preferential Flow Conditions
Shallow wells, porous cup samplers, and wick and gravity pan lysimeters were used to observe the movement of bromide applied to the surface of a grass covered field during a 23 day period....
Percolation Lysimeters for Water Quality Sampling
A field method to measure, year-around, the quantity and quality of leachate under irrigated crops has been developed. A specific objective was to evaluate percolation lysimeters as tools...
Drainage Lysimeters for High Water Table Citrus Studies
Forty drainage lysimeters were installed in 1988 to conduct water quality and consumptive use studies for citrus. The lysimeters were designed to simulate the high water table conditions...
Use of Lysimeters for Determining Characteristics of Pore Water
Lysimeters have been installed and used during the cleanup and stabilization of several former uranium processing sites in the western United States. In particular lysimeters have been...
Use of Lysimeters to Monitor a Sanitary Landfill
A vadose zone monitoring program has been developed using basin lysimeters to evaluate the environmental impacts of a sanitary waste landfill. Lysimeter systems, consisting of collection...
Herbicides in Streams: Midwestern United States
Results from a 2-year study of 149 streams geographically distributed across the corn-producing region of 10 midwestern States show that detectable concentrations of herbicides persist...
