Presented is a guide for helping secondary school students investigate the litter problem, acquire litter control skills, and develop an anti-litter ethic. The manual contains a hierarchy of learning objectives, a pretest/posttest, background information on litter, and activities keyed to the learning objectives. Each lesson includes brief…

This booklet outlines the steps through which the sponsors of special outdoor events can reduce the amount of loose trash generated. The guide includes sample on-site checklists, pledges for donating litter bags and/or receptacles, and press releases, along with a fact sheet on waste handling attitudes and a questionnaire for use with personnel…

This module describes important criteria to use in evaluating land for waste treatment sites and tells where the necessary information for such evaluation can be obtained. Among the important criteria for evaluation are climate, land use of potential site and surrounding areas, topography, drainage characteristics, soil properties, and geology.…

This module examines the basic properties of soil which have an influence on the success of land treatment of wastes. These relevant properties include soil texture, soil structure, permeability, infiltration, available water capacity, and cation exchange capacity. Biological, chemical and physical mechanisms work to remove and renovate wastes…

This module describes the following conventional treatment systems and evaluates their use as pretreatment steps for land application: preliminary, primary, secondary, disinfection, and advanced waste treatment. Effluent qualities are summarized, a brief discussion of application systems is given, and cost comparisons are discussed in some detail.…

This module discusses the hydrologic considerations that apply to land application of wastes. These are precipitation, infiltration and percolation, evapotranspiration, runoff, and groundwater. Climatic considerations that relate to wastewater storage are also discussed. Particular emphasis is given to wastewater flow, precipitation, evaporation,…

A comprehensive, documented discussion of certain operating principles useful as guidelines for the analysis of industrial wastewaters is presented. Intended primarily for the chemist, engineer, or other professional person concerned with all aspects of industrial wastewater analysis, it is not to be considered as a substitute for standard manuals…

This study compared incentives and educational methods to motivate children to pick up litter and to prevent littering. Incentives did aid in getting litter picked up. One-sentence anti-litter statements, educational materials, and lectures reduced littering, but incentives did not. (MR)
