OFFENSIVE TRADES
There is only one offensive trade business established in the
district, and during the year no complaints were received in connection
therewith.
ATMOSPHERIC POLLUTION.
Complaints of atmospheric pollution were again confined to a
few specific areas, the main trouble being restricted to two particular
sources where intermittent regression in the conditions kept
occurring, and where continual efforts were made to try to improve
circumstances. Structural alterations at one source of trouble are
progressing and it is hoped that these will prevent further pollution
during the coming year.
During the second half of the year, equipment for the measurement
of atmospheric pollution was installed at three points in the
eastern part of the district and monthly analyses were carried out.
No evidence of marked atmospheric pollution was recorded during
that period. It is hoped to extend the scope of these investigations
in the coming year, when it should be possible to make a more
accurate assessment of the situation.
SWIMMING BATHS AND POOL
Enfield has two public swimming pools, a relatively modern
open air pool, built in 1932, situated next to the Sports Stadium,
and indoor baths at Enfield Lock, built in 1895.
As regards the purification of the water, the up-to-date method
of break-point chlorination with continuous filtration and aeration
has been in operation at the open-air Pool for many years, and this
gives a safe and pleasant bathing water.
Up to, and including, the 1953 season, the indoor baths used
the "Fill-and-empty" system, but a modern chlorination, filtration,
and aeration plant is now in operation and working satisfactorily.
Reports on the twice-daily examinations for chlorine content
and alkalinity of the water of both baths are sent to the Medical
Officer of Health, and Sanitary Inspectors take samples regularly
for bacteriological tests.
