A Risk-Based Evaluation of Best Management Practices to Control Agricultural Groundwater Contamination
The probabilities of groundwater contamination by pesticides under different management alternatives were evaluated in a single county in Oklahoma by coupling an agricultural infiltration...

Transport of Injected Produced Water: A Sensitivity Study
This paper deals with the development and application of a model to assess potential environmental effects on Underground Sources of Drinking Water (USDW) due to the presence of an improperly...

An Expert System for Groundwater Management with Applications to Collier County, FL
This paper describes techniques used in frequency analysis, time series model building, forecasting, up-dating, and mapping. Domain knowledge of experts is transferred into the system...

An Evaluation of Hazardous Waste Land Treatment Closure Options
The purpose of this research was to evaluate changes in the persistence and mobility of the residues remaining when hazardous waste land treatment (HWLT) sites are closed. This evaluation...

Design and Implementation of a Risk-Based Remedial Action Program for Underground Tank Removal at a Dioxin-Contaminated Site
The unknown or uncertain conditions often inherent in hazardous waste site remediation projects complicate the job of the responsible professional to adequately assess and manage associated...

A Local Approach to Regulating Toxic Air Contaminants
The Monterey Bay Unified Air Pollution Control District began developing a local toxic rule that would apply to a broad number of pollutants and yet be readily usable to a permitting engineer....

Agricultural Salinity?Nature, Extent & Concerns
This paper presents an overview on the nature, extent and concerns of agricultural salinity problems. The problem of salinity has extended beyond the farmlands, and the practice of saline...

Effects of Salts on Soils and Plants
Salinity is a major constraint to crop production in many irrigated lands of the world. Management practices are needed for the control of soil and water salinity. The development of appropriate...

Land Reclamation and Drainage Water Reuse
This paper presents a brief overview of two chapters appearing in 'Agricultural Salinity Assessment and Management Manual', K. Tanji, Edit., Irrigation and Drainage...

Irrigation and Drainage Practices
Salinity causes many problems in agriculture, by lowering production or requiring more intensive management on farms, or by degrading off-farm soils and waters. This paper describes causes...

Institutional, Environmental and Legal Issues
An evaluation of the subsurface agricultural drainage problems occurring on prime agricultural land on the west side of the San Joaquin Valley of California offers an insight into the...

Irrigation Agriculture: Is it Sustainable?
Irrigation in (semi-) arid climates can be managed in such a way that it can be sustained indefinitely. Salination can be avoided by providing adequate drainage. Drainage, however, exacts...

Cokriging for Evaluating Agricultural Pollution
Subsurface drainage data from irrigated lands near Twin Falls, Idaho were used. Total Dissolved Solids and NO₃-N were selected as variables. The...

Sensitivity of Non-Point Source Models to Net Rainfall
A sensitivity analysis of the ANSWERS model was conducted to explore the possible impact on model outputs of discretizing rainfall input data into short time increments of various durations....

A Multivariate Analysis of Stillwater Lakes, Nevada
Stillwater Lakes located in western Nevada has been experiencing an astounding number of fish and waterfowl deaths since August 1986. This problem is explored through a multivariate statistical...

Behavior of Total Zinc in the Similkameen River
Multiple linear regression analysis was used to: develop equations that summarize the relationship between total zinc and a set of water quality characteristics measured in the Similkameen...

Prediction of Overland Phosphorus Transport Using a Phosphorus Enrichment Ratio
The Guelph model to evaluate the effects of Agricultural Management Systems on Erosion, Sedimentation, and Phosphorus yield (GAMESP) of Rousseau et al. was used to calibrate the phosphorus...

Urban Stormwater Runoff Management
Local land use regulations managing stormwater runoff in new urban developments are the most practical and effective method to control pollutants in urban stormwater runoff or prevent...

Irrigation and Aquifer Management in Illinois
The ground-water resources in eastern Kankakee and northern Iroquois Counties, Illinois, have been used for irrigation for over 50 years. During the drought of 1988, 131 irrigation wells...

Groundwater Protection in New York State
Groundwater protection is implemented by a variety of governmental entities. At the state level, the Departments of Environmental Conservation (DEC), and of Health (DOH) are the agencies...
