The purpose of this module is to develop a general procedure to decide the feasibility of land application as a waste management alternative, given a specific problem situation. This information provides a framework within which to apply the information presented in all other modules in the program. An outline of the general procedure followed in…

Five elements are identified as being potentially hazardous in this module. These are boron, cadmium, copper, molybdenum, and nickel. The hazards to plants and animals posed by these elements are discussed in some detail. The sources of toxic elements in sewage and the factors that effect the uptake of toxic elements by sewage sludge are also…

This module discusses the characteristics of alternate sites and management schemes and attempts to evaluate the efficiency of each alternative in terms of waste treatment. Three types of non-crop land application are discussed: (1) forest lands; (2) park and recreational application; and (3) land reclamation in surface or strip mined areas. (BB)

This module expands on the introductory discussion of nitrogen in other modules. The various chemical forms of nitrogen found in land treatment systems are defined. Inputs from waste application as well as natural sources are quantified for typical situations. A discussion of nitrogen transformations in the soil includes mineralization and…

Information, demonstration projects, and other activities, pertaining to solid-waste-related research, available from the U.S. Environmental Protection Agency (EPA), are contained in this document. These EPA publications are reports of the research, development, and demonstrations in progress as authorized by the Solid Waste Disposal Act of 1965.…

Hospital studies indicate the need for an environmental/sanitarian specialist for control of nosocomial infection and maintenance of a quality environment. The author recommends these requirements for certification as a hospital environmentalist: academic studies including toxicology, epidemiology, hygiene, management, and an internship in…

The professional sanitarian with appropriate interpersonal skills is very qualified to be administrator of a sanitation program or general public health program or to function at all administrative levels of public health. His/her particular training and professional orientation prepare him/her for this role. (RE)

The observations and conclusions are reviewed of the more widely distributed works on the bactericidal efficacy of cyanuric acid based swimming pool disinfectants. (BB)

Explained is the process of investigating an alleged waterborne disease outbreak. The information is designed to help water personnel work more effectively with health authorities in tracing, controlling, and preventing waterborne disease. (Author/MA)

Discussed are some of the ways to handle municipal and industrial wastewater treatment sludge presented at the 1978 American Chemical Society meeting. Suggestions include removing toxic materials, recovering metals, and disposing treated sewage sludge onto farm land. Arguments for and against land use are also given. (MA)

Programs for calculating gravity flow using a Texas Instruments SR-52 and the Programmed Manning Equation are given and discussed. (MR)

Discusses a study which sought to determine if food service management training and certification resulted in more sanitary operations. Findings from site inspections, pre/post tests, and attitude surveys indicated that the program did not produce statistically significant differences between control and study groups but that improvements in…

The Environmental Health Science Technology Program was initiated by Middlesex County College in 1971 to provide the trained personnel needed by industry and government. Major areas needing environmental health technicians, the environmental health technology curriculum, and the on-the-job-training internship program are discussed. (BT)

The need for the health profession's increased participation in long-term land use planning is detailed. The relationship between land use and environmental quality is stressed and current land use planning activities are summarized. A joint health and land use project initiated by the Johnson County, Iowa Health Department is described. (BT)

A look at the five basic subsystems in the food service operation should make equipment selections easier. (Author/MF)
