Abstract The need for rapid assessment of bacterial contamination at beaches is well known. Bacterial concentrations change rapidly (Bohm, Whitman et al. 1995, Olyphant and Whitman 2004, Whitman and Nevers 2008). The persistence model regulates todays swimming with yesterdays Escherichia coli (E. coli) measurement. As a result, this beach management tool is known to be less protective of human health than desired but was still used at over 500 beaches in 2010. One method for meeting this problem has been to develop rapid analytical methods taking two hours of laboratory analytical time. This approach is becoming operationally available but at higher analytical cost (Setty 2012) than the slower cultural methods currently employed. These rapid analytical methods provide beach managers with the capability to advise swimmers about E. coli concentrations on the same day, but only if sampling, transportation, and data management time components can be completed within four hours, giving an overall time of 6 hours. This requires early field sampling and laboratories close to the beaches being sampled.
