Fugitive Particulate From Highway Construction, Kennard F. Kosky
Fugitive Particulate From Highway Construction, Kennard F. Kosky
Retrospective Theses and Dissertations
National ambient air quality standards for particulate matter have been promulgated since April, 1971. While effects of stationary sources on these standards have been examined, little research has been accomplished on the effects of fugitive particulate. This thesis examines the environmental impact of a fugitive dust source, Highway Construction. Using the High-Volume reference method for particulate sampling, the effect of Highway construction was determined. An analysis of concentrations, distance influences, meteorological influences, particle sizes and construction influences is presented. The data obtained from this study indicates the major influence of concentrations is a function of distance and sampling height. Particle …
Electromagnetic Fields In Water Treatment, Robert H. Fagan
Electromagnetic Fields In Water Treatment, Robert H. Fagan
Retrospective Theses and Dissertations
Properties and characteristics of colloidal systems are reviewed with a discussion of colloid systems to be found in natural and wastewaters. Current electric and magnetic field theory are reviewed and summarized to provide practical application of the theory to engineering problems in the environmental field. Literature of colloidal reactions to electrical and magnetic fields is discussed and reviewed to ascertain areas of potential application of electric and magnetic phenomena to natural and wastewater treatment systems having objectionable colloid suspensions. It is concluded that application of electrical fields (electrophoresis) does not currently hold much promise for practical applications in water treatment …

Osha's Impact On Industry, Paul Christ Noller
Retrospective Theses and Dissertations
On December 29, 1970, the President signed into law the Williams-Steiger Occupational Safety and Health Act (OSHA) of 1970, which became effective April 28, 1971. The purpose of this act is to assure safe and healthful working conditions for the nation's wage earners. The law provides that each employer has the basic duty to furnish his employees a place of employment which is safe from recognized hazards that cause death or serious physical harm. The implementation of the OSHA Act has been the most extensive intervention into the day-to-day operation of American Industry in history. Originally, employers expressed doubt that …
