It is concluded that bacteriological measurements of recreational water quality must be based on the detection of fecal contamination by all warm-blooded animals. Field data from numerous fresh water and estuarine pollution studies indicate a sharp increase in the frequency of Salmonella detection when fecal coliform densities are above 200 organisms/100 ml. Fecal coliform bacteria should be used as a baseline indicator system for evaluating the microbiological suitability of recreational waters. The recommended limit of 200 fecal coliforms/100 ml for primary contact recreational water use is consistent with research findings and field investigations.
