SECTION F.—WATER SUPPLY, MILK AND
FOOD AND DRUGS.
F (1 ). Water Supply.
The water in this district is almost exclusively supplied
by the Metropolitan Water Board. The water though possessing
a considerable degree of hardness, is of good quality and
is palatable. The supply is led direct into the dwellings
served, no standpipes being known to exist.
Routine examinations of such supplies have been under
taken throughout the year with completely satisfactory
results, and arrangements exist with the Kent County Council
for 2 samples of this supply to be submitted to the Laboratory
monthly for bacteriological examination.
