Degradation of Ground Water by Tetrachloroethylene
Ground water from many municipal water wells in California has been degraded by tetrachloroethylene (PCE) at concentrations above the drinking water standard. Investigations conducted...

Wellfield Protection Program in Broward County, Florida
The Potable Water Wellfield Protection Program was initiated early in 1981. It examined land uses in the County, made an inventory of potential ground water pollution sources, compiled...

Case Study: Design of Groundwater Quality Monitoring Systems
This paper demonstrates the fundamental aspects of the design an implementation of state-of-the-art groundwater monitoring system, using conventional design principles. Based on experiences...

Use of D-C Resistivity to Map Saline Ground Water
It has been estimated in previous studies that 23 square miles of the Oxnard aquifer, a member of a multi-layered aquifer system beneath the Oxnard plain in Ventura County, California,...

Principles of Ground-Water Protection
Successful wellhead protection activities depend on a thorough knowledge of the ground-water flow system and an understanding of how contaminants migrate through geologic formations. Once...

Connecticut's Wellhead Protection Program
Connecticut's Wellhead Protection Program was the first in the country to receive EPA approval and remains one of the strongest programs in the nation. The program is based on comprehensive...

Oklahoma's Ground Water Protection Strategy
This report examines Oklahoma's developing ground water protection strategy in light of the national strategy. We look first at relevant federal legislation and what EPA expects of a state...

Groundwater Management in Southern Florida
A water supply plan was developed by the South Florida Water Management District (SFWMD) for Hendry County, Florida as part of the Lower West Coast Water Supply Plan. In the course of...

Ground Water Management in Arkansas
Arkansas has historically enjoyed plentiful water and has typically resolved water conflicts with case by case application of common law. As agricultural, industrial and domestic water...

Statistical Decision Analysis for Interception Wells
In this paper we apply the Bayesian decision analysis to the engineering design of a groundwater interception well whose purpose is to capture a contaminant plume. Two decision variables...

?H and ?⁴C as Tracers of Ground-Water Recharge
Surface spreading of water from the Santa Clara River is used to recharge aquifers underlying the Oxnard Plain. These aquifers are divided into an upper system about 400 feet thick, and...

Evapotranspiration Data Management in California
This paper will discuss components of the California Irrigation Management Information System (CIMIS). CIMIS is an automated agricultural weather network operated by the California Department...

Use of the TETrans Model in Predicting ET Effects on Groundwater Quality
Recently Corwin and Waggoner (1991) developed a contaminant transport software package referred to as TETrans, (acronym for Trace Element Transport). TETrans is a useful preliminary assessment...

Predicting Water Quality as Affected by ET Using the Root Zone Water Quality Model
The Root Zone Water Quality Model (RZWQM) is a physically based simulation model used to predict water and solute movement running from, moving through, and leaching out of the root zone....

Irrigation Project Modernization
Project modernization for sustainable irrigation requires a design and operation plan which will provide water deliveries with flexibility and reliability at each level within the system....

Technology Transfer Lessons from a U.S. Water District
An interceptor canal will be constructed near the end of eight laterals to collect and transport operational discharge and returned farm deliveries to a reservoir for temporary storage....

Technology Transfer for Projects in South America
Engineering services were provided for three projects in South America. One project was located in the Pampa Region of Argentina and two others in northern Brazil. The projects were: 1)...

Promoting Private Irrigation Development: The Irrigation Sector Program Experience in Nepal
In 1988, Nepal embarked on development of an Irrigation Sector Program. The key ingredients of the program are direct farmer participation in irrigation development and establishment of...

Technology Transfer to Developing Countries
Foreign assignments have proven to be the most interesting and rewarding part of a career for many western professionals. For success, however, care must be taken to assure that the individual...

The U.S. Bureau of Reclamation?New Directions in Water Management and Conservation
The activities of the U.S. Bureau of reclamation are reviewed. Pacific Northwest Region, upper Deschustes River Basin Water Conservation Project, Northwest Cooperative Agricultural Weather...
