Eighteen 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 only
three cases was the appearance cloudy, and in one of these 100 bathers
were using the bath at the time of sampling. In no case, however, was
the bacterial count more than 5 per million, and in 12 samples (including
that taken with 100 bathers) there were no growths of bacteria.
Free chlorine ranged from 0.5 to 3.1 parts per million.
