Discusses the importance of teaching environmental chemistry in secondary school science classes, and outlines five examples of environmental chemistry problems that focus on major concepts of chemistry and have critical implications for human survival and well-being. (JR)

Discusses the sources and effects of nutrients in wastewater, and the methods of their removal in wastewater treatment. In order to conserve water resources and eliminate the cost of nutrient removal, treated effluent should be used wherever possible for irrigation, since it contains all the ingredients for proper plant growth. (JR)

A method of disposal is suggested that is superior to the dilution method. The proceudres are based on the conversion of the wastes to less toxic or harmless forms or neutralization, so that they won't be a shock to the sewage system, and then excess dilution. (Author/DF)

Discusses four elements of safety programs: (1) safety training; (2) safety inspections; (3) accident investigations; and (4) protective safety equipment. Also discusses safety considerations in water/wastewater treatment facilities focusing on falls, drowning hazards, trickling filters, confined space entry, collection/distribution system safety,…

Outlines a laboratory procedure which enables students to evaluate the contamination potential of surface impoundments and apply basic principles of hydrogeology to the land disposal of waste material. Includes a list of materials needed and directions for the instructor. (Author/DC)

Chinese planners are successfully combining the two seemingly contradictory policies of growth and conservation. Enhancement and preservation of China's natural environment and resources are in keeping with her primary goal of upgrading living standards. (Author/RE)

School districts are required to determine if asbestos-containing materials exist at school facilities and design and implement asbestos abatement. Reviews how to select a contractor, draft the contract, and ensure its proper implementation by complying with the law and avoiding liability. (MLF)

This article focuses on the strategies Hands across the River used to stop a mobile incinerator from being built a short distance from their neighborhood. The group gained support from Congressional representatives and local government in a battle against the U.S. Environmental Protection Agency. (LZ)

Biology and geometry students join forces to investigate a real world problem, recycling and landfill management. (ZWH)

Dynamics of a large, expensive, and controversial surface and underground evaluation of a radioactive waste management program at the Yucca Mountain power plant are reviewed. The use of private contractors in the quality assurance study complicates the evaluation. This case study illustrates high stakes evaluation problems. (SLD)

To determine how infectious waste is being defined, treated, and disposed, the Seattle/King County Department of Public Health conducted a waste survey and facility inspection at 26 hospitals and 22 medical offices. The results and conclusions are discussed in connection with a contemporary literature review. (65 references) (Author/JJK)

Surveys the attitudes of Iowans toward the use of treated sludge on farm lands. Responses were analyzed using stepwise regression to determine the attitude variance accounted for by various factors including trust, alienation, antitechnology, knowledge of sludge, knowledge of risk, and demographics. (Author/CCM)

Uses Geographic Information Systems (GIS) in a classroom exercise to examine the distribution of toxic release sites in Queens, New York. Creates a series of maps to examine the relationship between the locations of known toxic releases and demographic factors such as race, education, income levels, and linguistic isolation. (Contains 47…

This curriculum guide is designed to help teachers in the middle grades facilitate student understanding of the social and environmental implications and limitations of technological development. The nine activities offer students opportunities to explore social issues arising from the science and technology of the production and management of…

This activity has been designed to help students understand a variety of concepts related to water use, efficiency, and students' own impacts on their watershed. It is intended for use both in the classroom and at home. The first concept covered in this exercise is, "What is a watershed?" Ideally this concept will be conveyed in the context of the…
