Formed stool (faeces) and vomit contamination incidents pose a risk to the health of users. The only way to prevent the spread of disease is to immediately close the affected pool and undertake appropriate remediation.
Note that no remedial action is required for blood in the water provided an appropriate primary disinfectant residual is present.
In major contamination events it may be necessary to submit a sample of the water to show it is free of microbiological contamination before reopening. public swimming pools and spa pools operators should contact Public Health Unit for advice
