1976
Dubin, Fred S. | Mindell, Harold L. | Bloome, Selwyn
"A practical guide for the identification and management of a range of hazardous wastes, Waste Management Practices: Municipal, Hazardous, and Industrial integrates technical information including chemistry, microbiology, and engineering, with current regulations. Emphasizing basic environmental science and related technical fields, the book is an introductory manual for waste management as mandated by the Resource Conservation and Recovery Act and related statutes."--BOOK JACKET.

Salkin, Michael S. | Shouse, James Clark
Extract: The objective of this study is to explore the possibilities for designing and operating solid waste systems to serve counties or towns within counties not currently meeting the Oklahoma Solid Waste Management Act of 1970. a central hypothesis of this research is that economies of scale exist in the formation and operation of multicounty solid waste systems. cost reductions are assumed to be achieved through the sharing of facilities, equipment, management and the ability to obtain bulk and fleet discounts. to test this hypotheses four types of systems are analyzed.

Contribution of the soil to the migration of certain common and trace elements
1976
Fuller, W. H. | KORTE, N. E. | NIEBLA, E. E. | ALESII, B. A.
Quantitative information on the immobilization of potentially health-hazard trace elements (e.g., Cd, Co, Cr, Cu, Ni, Pb, Zn, etc.) to prevent their migration through soil to water sources is scant. Little knowledge has been generated for the development of basic management practices for trace element stabilization against migration and their ultimate movement into domestic waters and potential food channels. The research here provides “baseline” information as a beginning for the control of hazardous trace element migration through soils. The contribution of 11 U.S. soils to the mobility of some common and trace elements as influenced by four readily characterized waste stream and leachate vehicles—pure water, dilute acid, solutions resembling industrial wastes, and municipal landfill leachates—is reported. Data are presented showing that: (a) soils release potentially hazardous constituents which migrate at different rates depending on certain measurable indigenous parameters, (b) solubilizing and mobility effects are a continuing process, (c) even the cleanest aqueous vehicle can become a carrier of potentially hazardous trace elements, and (d) certain characteristics of the soil, even under the most ideal conditions, must be identified before a management plan can be developed for the control of hazardous constituents in waste disposal.

1976
Fast food lunches in Smithtown, New York and Clark County, Nevada have turned troubled food service operations around. Efficient business management practices were combined with a desire to give secondary students nutritious meals with the kinds of foods they want to eat. Such favorites as hamburgers, pizza, tacos, and milkshakes are featured, but requirements for a Type A lunch are met. Students are consulted about preferences and suggestions. Student participation in the lunch programs increased and plate waste was reduced.
