Beach streams can sometimes contain more bacteria than sea water, particularly after heavy rain. This can result in the water quality of beach streams not having as good water quality as the sea.
After heavy rainfall events, the water quality of a stream that crosses the beach and discharges into the sea may be contaminated due to surface water run-off from agricultural land, urban areas or septic tanks. This may give rise to an increased risk of infection in the stream and the sea.
Inlet streams are generally not tested and so there may be no information on their water quality. As a rule, it is best to avoid splashing or playing in beach streams. As with normal safety precautions, you are advised to not drink or swallow water from beach streams and to wash hands carefully with clean tap or bottled water before eating or handling food.
