Water and Nitrogen Management Practices in the Central Platte Valley of Nebraska
Contamination of groundwater by nitrogen leached from fertilizer on irrigated soils is related to the quantity of nitrate present, the leaching potential based on soil texture and percent...
Economic Evaluation of Treatment Alternatives for Nitrate-Contaminated Water Supplies
This paper discusses the economic feasibility of removing nitrates from water supplies. Potential nitrate treatment methods include ion exchange, reverse osmosis, bio-denitrification,...
Geohydrologic Aspects of Water-Quality Problems of the San Joaquin Valley, California
Salinity and selenium concentrations in shallow ground water of the western San Joaquin Valley, California, are related to the geomorphology and hydrology of the alluvial fans. High salinity...
Experimental Design for Parameter Estimation in Groundwater
Model parameters have to be estimated from historical input-output observations using inverse procedures of parameter identification. Unfortunately, because of the limitation of the quantity...
Groundwater Transport in a Heterogeneous Aquifer: Tracking a Complex Plume
The Tennessee Valley Authority (TVA) is conducting a large-scale groundwater research project as a part of the Electric Power Research Institute's (EPRI) Solid Waste Environmental...
3-Dimensional Groundwater Modeling of the West Coast Basin Barrier
This paper describes a practical application of groundwater modeling of seawater intrusion in southern California. The West Coast Basin is one of the major groundwater reservoirs underlying...
Critical Water Issues and Computer Applications
This book contains papers presented at the 15th Annual Conference of the Water Resources Planning and Management Division of ASCE. The theme of the conference was Critical Water Issues...
Landfills: Lessening Environmental Impacts
Controlled recycling of leachates within landfills accelerates abaeribuc microbial reactions, thus converting refuse organics to methane. The process also enhances the precipitation rates...
Systems for Artificial Recharge of Ground Water
Design and management of infiltration systems should be adapted to local conditions of water quality, climate, soil, hydrogeology, and environmental constraints. Aspects to be considered...
The Economic factors of Ground Water Recharge Projects
As a result of the Water Conservation and Water Quality Bond Law of 1986, the State of California is now providing low interest loans to local water agencies to finance ground water recharge...
Bureau of Reclamation's High Plains States Ground Water Recharge Program
The Bureau of Reclamation is conducting a two-phase program to demonstrate the feasibility of recharging declining aquifers in the 17 western states. The U.S. Geological Survey (USGS),...
Feasibility of Artificial Recharge to the Oakes Aquifer, Southeastern North Dakota
Based on measured well yields, initial surface infiltration rates, and ground-water quality, the Oakes aquifer can support a large-scale artificial recharge-irrigation project. An aquifer...
Ground Water Recharge Through Wells
Surface runoff water accumulates in natural depressions called playas on the Southern High Plains; most of it is wasted by evaporation. The water is turbid, but otherwise of good quality...
Analysis of Hydraulic Impacts at the Tucson Reclaimed Water Recharge Project
The Tucson Reclaimed Water Recharge site has been implemented with increasingly sophisticated calculation methods as data collection efforts advanced. Initial project scoping utilized...
Wastewater Recharge: Water Quality and Operations
The Green Valley Wastewater Treatment Facility began operations in its current configuration in 1981. It treats approximately 1 million gallons per day of municipal wastewater, with disposal...
Health Effects of Ground Water Recharge
A five year multidisciplinary research project was conducted to evaluate the health significance of using treated wastewater for ground water replenishment. The focus of the study was...
Planning Ground Water Recharge in Scottsdale, Arizona
Mined ground water has historically supplied the municipal water needs of the City of Scottsdale. State enactment of stringent ground water legislation has mandated an eventual termination...
Ground Water Recharge at United Water Conservation District, Ventura County, California
For more than 60 years United Water Conservation District and its predecessor district have recharged seven ground water basins in Ventura County, California with more than 2,100,000 acre...
Ground Water Recharge Through Excavated Basins
Excavated basins were used to bypass slowly permeable soils in the Southern High Plains and artificially recharge the Ogallala aquifer. Recharge rates with turbid playa water were as rapid...
An Approach to Quality-Orientated Management of Catchment Areas with Artificial Ground Water Recharge
In the Federal Republic of Germany the artificial ground water recharge is primarily used to replenish the ground water resources for municipal drinking water supply. Only in some cases...
