Abstract
A total of 357 water samples were collected from a public beach in northern Taiwan during beach season and the densities of enterococci were analyzed by Enterolert methods The mean enterococci level was 356 MPN/100 ml and ranged from 10 to 2005 MPN/100 ml which was classified as high contamination level according to the WHO water quality guideline 95 percentile 1000 MPN/100 ml Most of the deteriorated water quality conditions occurred during rainfall By excluding data from the rain days the overall beach water quality would be considered in the moderate contamination level 95 percentile 200–1000 MPN/100 ml Among the selected microbiological parameters tested the densities of total coliforms and enterococci exhibited the highest correlation r = 0449 p = 0009 followed by the concentrations of total coliforms and fecal coliforms r = 0403 p = 002 Nonetheless no significant correlation was found between enterococci and fecal coliform levels r = 0197 p = 0271
