The distribution of Pseudomonas aeruginosa (PA), the number of coliform bacteria and standard plate counts were investigated in river water in five urban parks and at two bathing areas upstream of a river in the summer of 2001. PA was detected at all the sampling stations. The number of PA was positively correlated with the standard plate counts (r=0.788) and also with the number of coliform bacteria (r=0.802). There were more PA and coliform bacteria in the river water in two of the parks than at the bathing areas upstream. In one of the parks, there was a remarkable difference in the amount of bacteria before and after the special summer clean-up. However, infants had been bathing in the river before this summer clean-up. The presence of PA warrants urgent improvement in the management of the park as well as regular monitoring to ensure that the river is safe for bathers.
