An evaluation of alternative treatment methods for trihalomethane reduction in public water supplies /
(1984)
Trihalomethanes are formed by the reaction of free chlorine with precursors (usually fulvic or humic acids) present in surface waters used as a source. One or more species of the trihalomethanes have been implicated as ...
A qualitative model for designing and implementing effluent trading programs.
(1999)
Effluent trading programs (ETPs) have been proposed as cost-effective alternatives to command-and-control regulations for surface water quality management. In addition to reducing environmental compliance costs, ETPs may ...
Iron and sulfur microbial processes applied to the biodegradation of organic contaminants in groundwater.
(1998)
This research emphasizes microbial/mineral interactions associated with Fe$\sp{3+}$ and SO$\sb4\sp{2-}$ reduction. Simplified methods are developed to evaluate Fe$\sp{3+}, $ Fe$\sp{2+}, $ and S mineral species. These ...
The use of fecal bacteria in the assessment of the environmental impact by concentrated animal feeding operations on water quality.
(2004)
Many sources of pollution, including agricultural, industrial, and urban sources, can increase a stream or lake's nutrient and bacterial concentrations. In order to improve water quality, these sources must be identified, ...
Social learning for sustainability: A local government approach.
(2000)
This research integrates theoretical constructs from the literature on social learning and policy innovation, together with site-specific information, in the creation of a decision-making schematic for environmental policy ...
The development of aquatic ecoregions in Oklahoma /
(1984)
This study was to determine if a technique could be developed for assigning aquatic ecoregions to streams in Oklahoma. It was determined that watershed attributes, generally available on a statewide basis, can be used to ...
Design of a general methodology for the evaluation and categorization of an environmental program with special reference to Costa Rica.
(1982)
This research essentially consists of two parts. In the first part, methodological studies were prepared as the basis for the development of the general methodology by which each government or institution can adapt and ...
Quantification of chlorophyll in small reservoirs using airborne video imagery.
(1998)
The primary objective of this study was to develop a rapid, economic method of assessing water quality and productivity in surface impoundments. Airborne video cameras equipped with narrow band filters were used to assess ...
Water reuse potential in the Valley of Mexico and design of a general methodology for the selection of the best water reuse alternative /
(1983)
The Valley of Mexico, as well as many other regions in the world, is experiencing acute water shortages mainly due to population explosion, industrial development, and limited water resources. The major objectives of this ...
