Although using a total coliform bacteria test in assessing bacteriological contamination in public swimming facilities has many specific benefits, the following are limitations with regard to its accuracy: 1) total coliform bacteria have the potential to rapidly multiply in polluted waters and may therefore provide false implications regarding the time pollution occurred; 2) total coliform bacteria tests may provide false negatives when certain species of Pseudomonas or secondary invaders are present; and 3) because coliform bacteria can be readily destroyed and inactivated by chlorine, the test may not be a good indicator for more chlorine-resistant organisms (Koren & Bisesi, 2003a; Salvato et al.
