SANITARY CIRCUMSTANCES OF THE AREA.
Water.
The Metropolitan Water Board is the supplying
authority.
The supply to the Crayford District is a mixture
of water from Crayford, Dartford, Darenth, Wansunt and
Wilmington wells. All the water was chlorinated on the
works, but any chlorine remaining after a period of contact
was removed completely.
Bacteriological analyses were made five times per
week for all supplies both before and after chlprinatio
and 100 per cent. first class results were obtained during
the year.
All new and repaired mains were chlorinated before
being restored to use and samples of water from them'
were tested bacteriologically.
There was a serious pollution of the Crayford Well
at the beginning of April, 1950, with the result that the
station was out of service until the end of ajnuary, 1951.
Although there was gross sewage contamination of the
well it was taken out of supply immediately on the first
signs of deterioration in bacterial quality, and no contaminated
water passed into supply.
