Abstract:
Eighty four samples of sea water were collected from Bangsaen Beach, Chonburi Province during June-December 2002. The correlations among coliform bacteria, E. coli, fecal streptococci and Vibrio spp. were determined. Coliform bacteria was found significantly correlated to E. coli and fecal streptococci with the correlation coefficient of 0.432 and 0.596 respectively. Considering the correlations among bacterial numbers of each station, coliform bacteria was correlated with E. coli at Bangsaen Beach Resort Hotel and Windsurf Club. It was also correlated with fecal streptococci at Bangsaen roundabout, Lamtan and Windsurf Club. Teh correlation with Vibrio spp. was found only at Bangsaen Beach Resort Hotel. From the results, fecal streptococci showed higher correlation with coliform bacteria than E. coli. Therefore it could possibly be used as index bacteria.
