Twenty-two bath samples were analysed by the Public Analyst.
It is standard practice to record the number of bathers who have
used the bath prior to the sample being taken and the number of
bathers in the pool at the time of sampling, and the appearance
of the water. In four cases the appearance was cloudy, but in two
of these over 200 bathers were using the bath immediately prior
to the time of sampling. In 16 cases the bacterial count was
not more than 5 per million and in four it was under 10. Free
chlorine ranged from 0.2 to 3 parts per million.
