Biological Clogging and Rehabilitation of Drains and Well Systems and the Implications on Groundwater Quality

A Multiperiod Approach for the Solution of Groundwater Management Problems using the Outer Approximation Method
In a previous work the Outer Approximation method was presented (Karatzas and Pinder, 1993 and 1996) for the solution of groundwater management problems where the selected pumping rates...

Comparison of Stochastic Programming and Robust Optimization Models for Groundwater Plume Containment
Stochastic optimization models for containing a groundwater contaminant plume through the installation and operation of pumping wells are developed. Two related formulations are presented—stochastic...

Flexible Water Deliveries: One District's Experience
The Merced Irrigation District (MID) has implemented two significant incentive programs in 1995 to provide surface irrigation water to farmers who have shifted to private wells for irrigation....

Artificial Recharge of a Buried Glacial Aquifer in South Dakota
The Huron Project of the High Plains States Groundwater Demonstration Program was designed to artificially recharge a buried glacial aquifer in eastern South Dakota High flows from the...

Optimal Well Locations for Groundwater Mound Control

Wellhead Protection Area Predictions and Implications for the Biscayne Aquifer in Miami, Florida
The need to protect groundwater supplies from sources of contamination is of particular relevance to densely populated urban areas, such as Dade County (Greater Miami), in South Florida....

Wellhead Protection: Local and Community Efforts
The need to protect groundwater supplies from sources of contamination is of particular relevance to densely populated urban areas, such as Dade County (Greater Miami), in South Florida....

Juvenile Fish Separator Design
Separation by size of downstream migrant juvenile salmonids at hydroelectric projects in the Columbia River basin is an integral part of transportation and bypass programs. However, separation...

Regional Groundwater Management with Health Risk Assessment
A regional groundwater system may have several areas which are contaminated with organic chemicals. In general, the objective of groundwater management is to supply the demand for water...

Effect of Surface Water and Ground Water Interaction on Atrazine Transport to Pumping Wells
High concentrations of agricultural chemicals in flood waters have been reported in many Midwestern rivers and streams. The public water supply wells of a number of riparian communities...

Use of Artificial Neural Networks for Agricultural Chemical Assessment of Rural Private Wells
The detection of agricultural chemicals in rural private wells has prompted for numerous studies at regional, state, and national levels. A principal concern arises from the fact that...

Simulation of Unsaturated Zone Virus Transport Adjacent to Municipal Wells
The EPA proposed groundwater disinfection rule for municipal wells would allow exemptions if, among other options, the necessary virus source setback distance could be maintained to provide...

Beneficial Aspects of Flood and Rain in Countries Where the Drinking Water is Naturally Contaminated with Fluoride Where Fluorosis is a Major Public Health Problem
Floods, although considered destructive, have beneficial aspects too. This report is about one such instance where flood waters are considered extremely beneficial in countries where drinking...

Anaheim State-of-the-Art Water Treatment Plant—Six Years from Conception to Completion
After six years of intensive planning, budgeting, pilot testing, design, and construction, the City of Anaheim, California, has successfully completed the modifications to the 15 mgd Lenain...

Conjunctive Water Use Transforms a California Desert
An area doing multi-billion dollar recreational and agricultural business in the Southern California Sonoran desert owes its existence and well being to two things—wise water planning...

Use of δ¹8O and δD to Define Seawater Intrusion
On the basis of previous studies, more than 60 km² of upper aquifer system underlying the Oxnard Plain was believed to be intruded by seawater. Recent work has shown that there are sources...

Economic Impact of Managing Sea Water Intrusion
Sea water intrusion into a coastal aquifer may result from continued over extraction of the aquifer. In many coastal communities, sea water intrusion has led to artificial recharge programs...

Numerical Modeling of Deep Well Injection Near a Fault

Operation and Maintenance of Ground Water Facilities
The objective of this manual, Operation and Maintenance of Ground Water Facilities (Manual 86), is to point out the many factors that need...
