Chapter A7. Biological IndicatorsNational Field Manual for the Collection of Water-Quality Data (TWRI Book 9)7.1 Fecal Indicator BacteriaBy D.N. Myers, D.M. Stoeckel, R.N. Bushon, D.S. Francy, and A.M.G. Brady This section of Chapter 7 is available as a pdf file: Download a copy of Adobe Acrobat Reader for free. AbstractFecal indicator bacteria are used to assess the microbiological quality of water because, although not typically disease causing, they are correlated with the presence of several waterborne disease-causing organisms. The concentration of indicator bacteria is a measure of water safety for body-contact recreation or for consumption. This report provides information on the equipment, sampling protocols, and identification, enumeration, and calculation procedures that are in standard use by U.S. Geological Survey (USGS) personnel for the collection of data on fecal indicator bacteria.
