Description:Fecal bacteria have classically been used for the determination of water safety, sanitary system functioning and environmental health. It is now apparent that the bacteria, both the indicator bacteria and fecal bacteria more generally, are ubiquitous and that other determinants of safety are required. This volume, which focuses on indicator organisms but also more broadly on fecal bacteria, reviews the state of the art, and will be of interest not only to basic scientists but to those in many fields who apply the science to manage environments and human health.
