Treatment And Disposal Of Hazardous Wastes In The East Central Florida Region, Tracey Bell Jan 1979

Treatment And Disposal Of Hazardous Wastes In The East Central Florida Region, Tracey Bell

Retrospective Theses and Dissertations

Although the East Central Florida area is not heavily industrialized, its dependence on groundwater resources makes it especially vulnerable to contamination by poor waste disposal practices. The East Central Florida area was studied to discover the nature and disposal of hazardous wastes generated. It was found that a large portion of hazardous wastes in the region were from very small industries, distributors, and even consumers. Three of the most toxic and/or voluminous waste problems in the area--metal plating wastes, pesticide wastes, and hospital wastes--were studied to determine available alternatives for disposal and their costs.

Mass Loadings Of Selected Water Quality Parameters For The State Of Florida, Charles D. Miller Jan 1976

Mass Loadings Of Selected Water Quality Parameters For The State Of Florida, Charles D. Miller

Retrospective Theses and Dissertations

The mass loadings of pollutants common in surface waters result from the discharges of many different sources. In the last few years it has been noted that nonpoint sources contribute more pollutants than point sources. This is because in many cases the point source discharges have been, by law, reduced drastically. In the State of Florida many water quality parameters were examined to estimate the mass loadings in streams related to, drainage area, average flow, land use, soil type and management practices. A total of sixteen streams were examined. The information was first calculated for mass loadings as a function …


"Storm", A Mathematical Model Applied To The Shingle Creek Basin, Jay G. Foy Jan 1975

"Storm", A Mathematical Model Applied To The Shingle Creek Basin, Jay G. Foy

Retrospective Theses and Dissertations

Stormwater management necessitates a regional plan based on the best practical methods. "Storm", a mathematical model, is employed to simulate runoff conditions in the Shingle Creek Basin. The computed runoff quantity is calibrated directly with the streams hydrograph. Runoff quality is predicted with two sets of pollutant loading rates. The scope of the model is expanded by development of parametric curves that can be used to convert measured quality data to input land use loadings. A parametric study is also performed to fabricate the effects of urbanization on the Shingle Creek Basin.
