Phosphorus chemistry under aerobic and anaerobic conditions in model two-celled waste stabilization ponds.
(1980)
This study involved a laboratory examination of the phosphorus interactions between the sediment and water as they occur on a diurnal basis in a waste stabilization pond under summer conditions in the southcentral U.S. At ...
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 ...
Research to establish ecological standards for water resources developments.
(1981)
Three levels of development were identified to represent the environmental condition of the region under consideration. The least disturbed environments are designated as level I areas to which the strictest ecological ...
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 ...
Coupled modeling of the air quality impacts of chemical depainting agents released from an industrial wastewater treatment facility.
(2001)
Coupling of an appropriate source emissions model and an atmospheric dispersion model represents a cost-effective and environmentally-responsible approach for meeting impact prediction and regulatory reporting requirements, ...
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 ...
