Swimming is an enjoyable and healthy pastime for many people. However, swimming pools can be a source of infection if the water is inadequately treated.
With regular use, changing numbers and treatment, the pool water chemistry is very complex and requires consistent monitoring. It is necessary to examine the chemical and bacteriological quality of the water to ensure it is safe for use.
Monitoring is undertaken by simple tests at the poolside and chemical and bacteriological samples are taken for more thorough analyses. The monitoring is the responsibility of the pool operator.
As a basic public health measure, Environmental Health monitors the quality of swimming pool waters by an annual programme of sampling.
