Swimming Baths
There are two municipal-owned swimming baths in the district, one at West Hendon
and one at Mill Hill. The long, hot summer produced big attendances at both, a
total of 170,596 persons using Mill Hill bath and 67,438 West Hendon.
Visits are paid by the Public Health Inspectors and samples taken of the water,
particularly during hot weather when the baths are most frequently used.
Swimming bath water often in advertently becomes drinking water, particularly
where schoolchildren are concerned, and therefore the water in swimming baths should
as nearly as possible reach the standard of drinking water.
The cleanliness of these swimming pools is quite remarkable when compared with
the bacteriological standards reported by the Medical Research Council (Memorandum
No.37) which followed an investigation into the contamination of bathing beaches in
England and Wales. In this report a typical beach examined by the Medical Research
Council showed a coliform count which ranged between 40 per 100 ml. at the lower end
of the scale to 25,000 per 100 ml. at the upper end of the scale.
30 samples were taken at the two Hendon pools, and no coliform organisms were
found in any of these samples. Report No.71 of the Ministry of Health in the
Bacteriological Examination of Water Supplies also recommends that in 75% of the
samples taken, the 24-hour plate count at 37°C. from 1 ml. of water should not
exceed 10 colonies and the remainder should not exceed 100 colonies. Of the 30
samples taken 75% did not, in fact, exceed 10 colonies and in only 2 cases did the
count exceed 100 colonies. One of the latter samples was found to have been due to
the chlorinator having been out of action for some 2 hours prior to the taking of
the sample, due to a burst water main. The other sample was taken after August Bank
Holiday week-end, when there had been very high attendances at the bath.
