The temporal distribution of indicators (faecal coliforms and faecal streptococci) and opportunistic pathogens (Candida albicans and Pseudomonas aeruginosa) at a Lake Ontario bathing beach on high and...: En13-5/85-45E-PDF
"In order to examine the temporal relationship between bather load and water quality indicator levels, faecal pollution indicator (faecal coliforms and faecal streptococci) and opportunistic pathogen (Candida albicans and Pseudomonas aeruginosa) levels were monitored hourly in the nearshore waters of a shallow Lake Ontario bathing beach on a hot August day when the bather load was high, and on two overcast August days when the bather load was negligible. On the high bather load day, an increase occurred in the numbers of faecal coliforms and faecal streptococci in the beach water in conjunction with an increase in the bather load; P. aeruginosa levels increased later in the day. There was little apparent relationship between C. albicans levels and the other parameters which indicates that, on the high bather load day, C. albicans levels could not be predicted by either bacterial indicator levels or bather loads. No corresponding increases were observed for any of the monitored parameters on the low bather load days. The results suggest that bather load and sample collection time may interact to influence estimations of recreational water quality based on faecal pollution indicator and P. aeruginosa levels"--Abstract.
