ENVIRONMENTAL HEALTH„
1. WATER SUPPLY„
The whole of the area is supplied by the Metropolitan Water Board
and the supply has been satisfactory both as regards quantity and
quality,, In view of the large number of routine bacteriological and
chemical examinations carried out by the Water Examination Department of
the Board it was not considered necessary to make routine tests but three
samples were taken when investigating complaints and proved to be satisfactory.
Well water is used for industrial purposes at certain factories, but
is not used for domestic consumption all the houses in the town being
provided with a main water supply.
Fluoridation is commented upon in the preamble to the report by the
Medical Officer of Health„
