15.-BACTERIOLOGICAL EXAMINATION OF WATER SUPPLIES.
The number of samples of water examined during the year was 1,791, an increase of 292 samples over last year. The following table gives the sources from which these samples were obtained:-
Tap waters in Victoria and Kowloon 1,074 Filter Bed samples for Water Authority 233 Well waters for M. O. H. 70 Imported River Waters from West Rivers &c. 76 Public Tank supplies 162 Nullah water for P. W. D. 17 Miscellaneous samples 159 Total 1,791The private water supplies of the Dairy Farm were examined weekly. Specimens were also examined on several occasions at the request of a sugar factory, dockyard and mineral water factory; all the above supplies were satisfactory.
The public water supplies both in Victoria and in Kowloon continue to maintain a high standard of purity.
Domestic filter candles were examined and sterilized regularly for various Government and other Institutions, the total number dealt with being 352.
The necessity for importing large quantities of highly polluted river water into the Colony during the recent drought threw a large amount of extra work on to the Government Analyst together with the Institute; but thanks to prompt chlorination and efficient control a constant supply of excellent potable water was maintained.
