The purpose of this study was to develop e-learning activities that could facilitate the integration of sustainability concepts and practices in engineering and chemical education. Using an online learning management system (LMS), undergraduate students in an applied chemistry program at a public university in Zimbabwe participated in an online…

The Paso del Norte segment of the Rio Grande experiences two seasons per year; the (wet) irrigation season and the (dry) non-irrigation season. The goal of this study was to improve the understanding of occurrence and contribution of dissolved metals in this region during the non-irrigation season. The objectives of this study were to (1) evaluate…

Designed to assist community college administrators and faculty in enhancing vocational education programs and services, this Vocational Education Resource Package presents case studies of four partnerships between California community colleges and industry and offers guidelines for developing successful partnerships. The case studies focus on:…

This case study applies principles derived from the Center for Regenerative Studies (CRS) to a community college in North Carolina. CRS, on the campus of California State Polytechnic Institute (California), is dedicated to the education, demonstration, and research of degenerative systems in the areas of shelter, food production, energy, water and…

Exclusion of some forms of tax revenue and all forms of nontax revenue and support from measures of tax effort for allocating federal revenue sharing funds appears to introduce systematic bias against rural/nonmetropolitan local governments. Omitted tax revenues include those for schools and special districts (rural communitites raise…

The ability of various treatment processes, such as oxidation ponds, chemical coagulation and filtration, and the soil mantle, to remove the agents of infectious disease found in waste water is discussed. The literature concerning the efficiency of removal of these organisms by various treatment processes is reviewed. (BT)

This manual for sewage treatment plant operators was prepared by a committee of operators, educators, and engineers for use as a reference text and handbook and to serve as a training manual for short course and certification programs. Sewage treatment plant operators have a responsibility in water quality control; they are the principal actors in…

An examination of activated sludge treatment to determine the effect of increased waste concentration caused by water conservation measures is described. (MR)

Based on the idea that the prevention and treatment of water pollution should begin at its source, this document focuses on some methods that individuals can use in their homes and businesses to treat wastewater. Chapter one, "What Is the Water Crisis?" explains the basic concepts of the hydrologic cycle, evapotranspiration, and the quantity of…

Presents a literature review of agricultural wastes, covering publications of 1976-77. Some of the areas covered are: (1) water characteristics and impacts; (2) waste treatment; (3) reuse of agricultural wastes; and (4) nonpoint pollution sources. A list of 150 references is also presented. (HM)

This general information pamphlet is concerned with the types of wastewater treatment systems, the need for further treatment, and advanced methods of treating waste. Current methods are described, illustrated and evaluated. Pollution problems from oxygen-demanding wastes, disease-causing agents, plant nutrients, synthetic chemicals, inorganic…

Discusses the possible health hazards resulting from released nucleic acid of inactivated viruses, chlorinated nonliving organic molecules, and overestimated reliability of waste treatment standards. Suggests the recycle system use a dual disinfectant such as chlorine and ozone in water treatment. (CC)

Most waste treatment techniques conceived to meet the 1977 standards can be separated into three distinct phases: primary, secondary and tertiary treatment. An examination of the four heaviest industrial water users, pulp and paper, steel, plating, and food processing, demonstrates these treatments use proven technology to meet specific…

Water pollution techniques and practices, including data analysis, interpretation and display are described in this book intended primarily for the biologist inexperienced in this work, and for sanitary engineers, chemists, and water pollution control administrators. The characteristics of aquatic environments, their biota, and the effects of…
