Our present sewage disposal systems are ecologically unsound because they risk transmitting diseases, waste water, cost too much, increase lake eutrophication, and build up sludge. Sewerless toilets are being developed which can solve these problems. (MR)

The physiological effects on humans and animals of trace amounts of organic and unorganic pollutants in natural and waste waters are examined. The sensitivity of particular organs and species is emphasized. Substances reviewed include mercury, arsenic, cadmium, lead, chromium, fluorides, nitrates and organics, including polychlounated biphenyls.…

Participants in the D-19 symposium on aquatic sampling and measurement for water pollution assessment were informed that determining the extent of waste water stream pollution is not a cut and dry procedure. Topics discussed include field sampling, representative sampling from storm sewers, suggested sampler features and application of improved…

The technical and economic feasibility of constructing and operating a rapid sand filtration sewage treatment system as an adjunct to a waste water stabilization pond is investigated. The study concludes that such units are within the technical and economic constraints of a small community and comply with the EPA criteria. (BT)

More than 60 successful programs and projects developed specifically under Title V of the Rural Development Act of 1972 by 13 southern states and Puerto Rico are reported in this synopsis of Title V achievements in the southern region. A summary of benefits to people in 82 pilot counties of the rural South lists improved job opportunities, homes,…

Reviews New York City's Environmental Protection Administration two-year effort in air, water, noise, and solid waste pollution control. Successes and difficulties are seen as applicable to other urban areas. Long-term planning considers population control, poverty programs, traffic management, and land use. (JM)

This module discusses some of the objectives of incorporating vegetative cover in land treatment systems. Specific crops and forest cover are mentioned in relation to benefits associated with each, and specific treatment alternatives (irrigation, overland flow, and rapid infiltration) are included in relation to vegetative cover considerations.…

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 enumerates the benefits to be derived from cropping at a waste application site and criteria to be used in selecting a crop for use in a particular situation. Following basic discussions of the requirements of various crops for water, soil-plant-air moisture potentials, crop water tolerance, nutrient removals by various crops, and…

This module summarizes laws that are relevant to the land application of wastes, focusing on the applicable Federal laws and representative state regulations from different areas of the country. The module describes the 10 points of Public Law 92-500, the Federal Water Pollution Control Act Amendments of 1972, that relate to land application. It…

The Highland Park environmental health plan includes the following components: Legal and administrative and programmatic relationships, planning studies, residential environment, disease vector control, water and sewage systems, sanitation, air pollution, food protection, industrial and radiological health, and solid waste facilities. (JR)

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.…

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…

This module summarizes four major reasons for employing monitoring during design and operation of a land application site: documentation of existing water quality and system performance, confirmation of design parameters, provision of data for future designs and for management decisions. Monitoring requirements are examined for different land…

This publication contains information relating to waste prevention, treatment and disposal, and waste product utilization. Its primary purpose is to provide information that will help the food industry executive recognize waste problems and make wise management decisions. The discussion of the methods, techniques, and the state-of-the-art is…
