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...
Multiple Treatment System for Phosphorus Removal
Detention ponds, wetlands, and infiltration basins have each been shown to reduce constituent loads carried by urban stormwater, including phosphorus. Design recommendations are presented...
Swedish Approach to Infiltration and Percolation Design
Design of infiltration and percolation facilities is similar to detention facilities. The storage volume of an infiltration basin being the ponding volume on top of the infiltration surface...
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),...
Artificial Recharge Research at the University of Arizona
This paper summarizes pit- and well-recharge trials at Tucson, Arizona. The pit recharge trials examined management techniques and characterized flow patterns in the 80 ft thick vadose...
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...
Hydraulic Effect of Turbid Water Infiltration Through a Shallow Basin
A 225 m2 test basin was operated from September 1986 through October, 1987, to determine the hydraulic effects of turbid water application. Initial...
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...
Artificial Recharge and Water Supply in The Netherlands
In 1984 infiltration by surface spreading was 156 million m3, serving 15% of total supply of drinking water in the Netherlands. Already for some...
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...
Bacterial Fingerprinting to Trace Source of Coliform Bacteria During Artificial Recharge
This report describes the use of a bacterial 'fingerprint' technique to determine if treated effluent from infiltration beds was the source of coliform bacteria...
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...
Quality Changes of River Rhine and Meuse Water Upon Basin Recharge in the Netherlands' Coastal Dunes: 30 Years of Experience
A wide spectrum of quality changes of river Rhine and Meuse water is presented, on a global scale after pre-treatment, dune infiltration and post-treatment. Attention is focussed on the...
Benefits and Risks of Artificial Recharge of Saline Aquifers
Artificial recharge of saline aquifers by deep well injection of treated effluents is attractive, as it provides a solution to an environmental problem, and possibly creates groundwater...
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...
