Objective To know the present sanitary status of bathing beach in Haikou,and provide the scientific data for improving the assessment of microorganisms contamination of bathing beach. Methods The routine water quality data and related meteorological data of the bathing beach were collected from 2007 to 2009. In July 8th-10th 2009,a high grade bathing beach and an ordinary one were selected,four sampling sites were selected where the contamination by feces were often seen,the number of swimmers was the largest,the samples were collected from the deep-water areas and sand beach respectively,and fecal coliform and enterococcus were examined. Results The concentration of fecal coliform was(1 085.8?538.8)cfu/L in water and(120 000.0?32 659.9)cfu/1 000 g in sand,and the E.faecalis was(32.5?19.1)cfu/L in water and(2 425.0?689.8)cfu/1 000 g in sand. The numbers of the two kinds of bacteria in water decreased with the increase of distance from the land. The concentration of bacteria was positively correlated to the day's rainfall(P
