SUMMARY OF REPORTS ON WATER SAMPLES SUBMITTED FOR BACTERIOLOGICAL EXAMINATION, 1934.
Report No. and Date. | Organisms produced on gelatine plates incubated at 20°C. for 3 days. | Organisms produced on agar plates incubated at 37.5CC. for 2 days. | B. Coli. | Streptococci. | B. Enteritidis Sporogenes. | REMARKS. |
---|---|---|---|---|---|---|
1656 (Godfrey's Farm) 15/1/34 | 1,580 per c.c. | 260 per c.c. | Present in 2 c.c. | Present in 10 c.c. | Present in 25 c.c. | The sample contains a considerable number of excremental organisms and is not fit for drinking purposes in its present condition. The surroundings of this well are undesirable in a domestic supply and there is some evidence to suggest that the water has been in a worse condition than it is at present. |
14720 (Victoria Cottages) 23/3 34 | 7,400 per c.c. | 24 per c.c. | Present in 2 c.c. | Present in 10 c.c. | Present in 25 c.c. | The water contains a considerable number of excremental organisms and there are indications that it has been in this state for a considerable time. It should not be used for drinking purposes, but if there is no alternative supply the water should be boiled before use. |
14721 (Bet-linge Cottages) 23/3/34 | 320 per c.c. | 7 per c.c. | Present in 100 c.c. not found in less. | Not found in 30 c.c. | Not found in 100 c.c. | The examination shows a few B.Coli not associated with other excremental organisms and therefore not indicating definitely pollution with excrement. These bacilli might quite well be accounted for by the loose-fitting cover and sewage pollution is highly improbable. The water is reasonably safe for drinking as judged by this examination. |
32047 Pinkwell Cottages) 25/6/34 | 1,500 per c.c. | 375 per c.c. | Present in 25 c.c. | Present in 30 c.c. | Present in 100 c.c. | The water is found to contain a large number of microorganisms a small percentage of which are of excremental origin. The close proximity of manured land and animals and the comparative nearness of a cesspool are undesirable features and it might be advisable to boil the water before drinking. |
53248 (S.W. Suburban Water Co.) 31/10/34 | 12 per c.c. | 7 per c.c. | Not found in 100 c.c. | Not found in 30 c.c. | Present in 100 c.c., not found in less | The sample contains a few objectionable spores but taking the result as a whole the water can be regarded as suitable for drinking purposes from a bacteriological point of view. |
53249 (Rickmans-worth Water Co.) 31/10/34 | 80 per c.c. | 26 per c.c. | Not found in 100 c.c. | Not found in 30 c.c. | Not found in 100 c.c. | The sample contains a few short streptococci in a quantity over 30 c.c. but as they are not of a faecal type they can be disregarded. The water is suitable for drinking purposes from a bacteriological point of view. |
53250 (Allied Building Corpn.) 31/10/34 | 11 per c.c. | 6 per c.c. | Not found in 100 c.c. | Not found in 30 c.c. | Not found in 100 c.c. | The sample .shows a low bacterial contence and no excremental types of bacteria are present. From a bacteriological point of view this water is of excellent quality. |
