Book Description
Fluoride is known to occur at elevated concentration in a number of parts of the world, where it can be a significant cause of disease. The primary focus of this book is the prevention of adverse health effects from excessive levels of fluoride in drinking water. The book fills the urgent need, identified for updating the WHO Guidelines for Drinking-water Quality, for information on the occurrence of fluoride, its health effects, ways of reducing excess levels, and methods for analysis of fluoride in water. The draft document, produced by a working group of experts convened to consider protection from fluoride and its control, was issued for extensive review and consultation. The resultant book, which incorporates the comments received, was further peer reviewed by experts in developed and developing countries. It is aimed at a wide range of individuals, including health workers and sanitary engineers who may require a broad introduction to the subject with more detailed guidance in some specific areas. Fluoride in Drinking-waterwill be an invaluable reference source for all those concerned with the management of drinking water containing fluoride and the health effects arising from its consumption, including water sector managers and practitioners, as well as health sector staff at policy and implementation levels. It will also be of interest to researchers, students, development workers, and consultants.

Book Description
FROM THE INTRODUCTION Over the past decade, industrial water pollution control has undergone vast changes. Public Law 92-500 passed in 1972 primarily targeted conventional pollutants such as Biochemical Oxygen Demand (BOD) and suspended solids and as a result wastewater treatment plants were designed to meet these objectives. In recent years volatile organics, priority pollutants, aquatic toxicity and some heavy metals have received attention in specific industrial effluents. In some cases nitrogen and phosphorus will have specific effluent limitations. If the wastewater contains volatile organics such as benzene or toluene, these organics must be removed prior to biological treatment or basins must be covered with off-gas treatment. The technology choice to meet these objectives in a cost-effective manner will be site specific. In 1976 EPA established effluent limitations for priority pollutants in the organic chemicals, plastics and synthetic fibre industries (OCPSF). These are pollutant specific guidelines expressed as an effluent concentration. Depending on the specific chemical involved, the biological treatment process or a source treatment technology may provide the most economical solution. Aquatic toxicity poses a major problem in industrial water pollution control. Because it is frequently non-specific it is difficult to identify appropriate cost effective technologies. As a general rule, biological treatment should be the first option with more costly physical chemical technologies employed only in cases where the toxicity-causing chemicals are non-biodegradable.
