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...
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...
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...
Importance of ET on Colorado River Water Quality
Salinity is a major problem in the Colorado River. About 37 percent of the salt loading is contributed by irrigated agriculture activities. Deep percolation and seepage from irrigated...
Rehabilitating Irrigation Systems with USDA Water Quality Programs
Recently, the United States Department of Agriculture (USDA) targeted several irrigated areas with chemically-impaired water bodies for accelerated technical and financial assistance to...
Water Quality Implications of Encapsulated Atrazine
This paper presents the movement of both encapsulated and wettable powder atrazine under no-till and conventional-till corn in the Coastal Plain physiographic region of Maryland. Soil...
Expert System for Agricultural and Water Quality Management
Agricultural activities occur in an open environment where uncontrollable climatic events influence both agricultural productivity and water quality. A decision support system is described...
Management of Agricultural Drainage Pollution Considering Regional Cooperation
Increasing awareness of toxic substance discharge from agriculture in the San Joaquin Valley of California has resulted in discharge limits on individual constituents in agricultural drainage....
Prediction of Sedimentgraph from a Small Watershed in Poland in a Changing Environment
Estimates of sedimentgraphs and temporal distributions of sediment concentrations are essential for prediction of pollutant concentrations in streams and reservoirs. In such predictions,...
Climate Change and Water Management Flexibility
Changes in regional climate expected to occur as a result of the accumulation of greenhouse gases may have significant impacts on water resources. In this paper, I examine the sensitivity...
Waste Water Management at Bulk Terminals
As North American environmental regulations become more demanding, the amount of contaminants permitted in waste water discharge is reaching lower levels than can be achieved by conventional...
Soil Contamination Issues at Port Marine Terminals
A preliminary survey of hydrocarbon contaminated soil and groundwater problems in U.S. west coast ports indicates that the problem occurs in most major port areas. Using the Port of Los...
Clean-Up of Contaminated Soils: A Necessary First Step in Industrial Land Redevelopment
This is a paper describing efforts by The Toronto Harbour Commissioners to demonstrate how several technologies can be effectively integrated to remove or reduce contaminant levels in...
Dredging Contaminated Sediments: A Monitoring Plan for Boston Harbor
Dredging and blasting will be conducted in Boston's Inner Harbor over approximately a one-year period during construction of the Third Harbor Tunnel. The silty organic surface sediments...
Analysis of Dredged Material Deposition Patterns
Between November 1, 1989 and 30 March, 1990, nearly 1 million cubic yards of dredged material were disposed in Puget Sound as the first phase (Element I) of the construction of the Navy's...
Bulk Commodity Terminals?Planning for the Future Competitive and Environmental Challenges
The demand upon all industries for better protection of the environment is increasing and the regulations and permit requirements are changing rapidly. Bulk commodity terminal operators...
Global Warming and Possible Effects on the Central and Southern Florida Project
The possible impacts of global warming on the operation and management of the Central and Southern Florida Project are examined. The potential impacts include sea level rise, tropical...
