Chemical speciation and flyash stabilization of arsenic, barium, chromium, and lead in drilling fluid wastes /
(1984)
Another laboratory study was conducted to determine the behavior of metals within drilling fluid wastes stabilized by the addition of flyash. Drilling fluid wastes were mixed with varying proportions of flyash ranging from ...
Methodology for the selection of appropriate technology of water distribution systems in less developed countries /
(1984)
The output can be used by promoters, designers, planners, and the community to determine in advance the needs for manpower and the water rates that are necessary to be met in order to maintain the water distribution system ...
Land treatment of oil refinery sludges :
(1984)
Sampling, sample preparation and analysis methods developed for the measurement of oil content yielded consistent results. The developed method was used to study the degradation of oil with time. The loss of oil ranged ...
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 ...
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 ...
Determination of volatile hydrocarbon emissions from land treatment of petroleum oily sludges /
(1984)
Experimental soil-disposal tests were conducted in the laboratory in a controlled environment and on the field plots. Approximately 4792 kg sludge was spread on the six experimental plots in the field over a six-month test ...
The selection of best management practices for controlling the non-point source pollution in Oklahoma /
(1984)
Both models start with a soil erosion and water quality packages which use the Universal Soil Loss Equation to predict sediment suspension; the sediment delivery ratio to estimate the actual sediment discharging into the ...
Characterization of aquatic use attainment in Oklahoma /
(1984)
This research describes the application of an aquatic use assessment methodology referred to as use attainability analysis (UAA). The EPA has issued guidelines governing the process of Water Quality Standards' review and ...
