As a result of the bacteriological examinations three adverse reports on drinking water were
received. These were thoroughly investigated and as a result of action taken the subsequent
sampling showed the water from these particular drinking points to be pure and potable.
Chemical analysis of water supplies was carried out by Dr. Amphlett Williams, the Corporation's
Public Analyst. Fourteen such samples were taken, all of which were satisfactory.
The Metropolitan Water Board have supplied the following Report:—
"(a) The supply was satisfactory both as to quality and quantity throughout 1966.
(b) (i) The supply was derived from the following works and pumping stations:-
River Thames (Southern)
New River via Stoke Newington
No new sources of supply were instituted.
(ii) The number of samples collected and the bacteriological and chemical analyses of
the supply from the above sources after treatment are shown on the attached sheets. No
fluoride was added, and where the fluoride content is indicated it represents the naturally
occurring fluoride in the water.
(c) The supply being hard in character is not liable to be plumbo-solvent.
(d) All new and repaired mains are disinfected with chlorine, after a predetermined period of
contact the pipes are flushed out and refilled; samples of water are then collected from
these mains; and the mains are returned to service only after results are found to be
satisfactory.
The quality control from these laboratories is carried out by means of daily sampling
from sources of supply, through the treatment works or well stations, from the distribution
system, and through to the consumer. Any sign of contamination or any other abnormality
is immediately investigated.
(e) (i) The Board has no record of the number of structurally separate dwellings supplied in
your area, but the population supplied direct according to the Registrar General's estimates
at 30th June, 1966, was 4,469.
(ii) No houses were permanently supplied by standpipe.
Other Observations
(f) There were no changes to the general scheme of supply in your area.
(g) There were no additions to the total yardage of mains in the Borough."
