About this book

In many countries wastewater treatment systems are hardly functioning or have a very low coverage, resulting in very poor quality water being used for irrigation and the cultivation of consumable produce. This can create significant risks to public health, particularly in expanding urban areas. "Wastewater Irrigation and Health" approaches this serious problem from a practical and realistic perspective, addressing the issues of health risk assessment and reduction in developing country settings.

The book therefore complements other books on the topic of wastewater which tend to target high-end treatment options or merely report that wastewater irrigation is a common phenomenon. The editors of "Wastewater Irrigation and Health" move the focus onto quantifying risk in order to reduce it. It presents the state-of-the-art on low-cost options for health risk reduction in line with the multiple barrier approach of the 2006 guidelines published by the World Health Organization.

'This book represents the best, modern innovative thinking on the topic and symbolizes an important turning point in the history of wastewater reuse in irrigation as a major contributor to water and nutrient conservation, public health and welfare.' Professor Hillel Shuval, Department of Environmental Health Sciences, Hadassah Academic College, Jerusalem and Professor of Environmental Sciences (Emeritus), Hebrew University, Jerusalem, Israel
