This guide to environmental health planning outlines the process and procedures of bringing together certain fundamental data pertaining to various physical aspects of the environment, including data collection, evaluation, usage, and implementation. The components of such planning programs are listed along with study preparation information. Emphasis is given to the evaluation of health related utilities and services that readily lend themselves to long-range planning, such as water, sewage, and solid wastes. Programs for dealing with air pollution and housing are mentioned in this connection. Data forms, study maps and the locations of U.S. Department of Health, Education and Welfare regional offices are included. (TG)
