SUMMARY OF REPORTS OF WATER SAMPLES SUBMITTED FOR BACTERIOLOGICAL EXAMINATIONS, 1938.

Report No. and Date	Organisms produced on gelatine or agar plates incubated at 20°C. for 3 days	Organisms produced on agar plates incubated at 37.5°C. for 2 days	B. Coli.	Streptococci	CI. Welchii. (spores)	Remarks
1965 15/1/38	4 per c.c.	3 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	The sample has a very low bacterial count and no organisms of an excremental type are present. The water is quite safe for drinking purposes.
1966 15/1/38	27 per c.c.	3 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 results show the presence of a few excremental organisms, they are only present, however, in quantities of 100 c.c., and although the water is not of the highest degree of purity it might be considered reasonably safe for drinking purposes.
1967 15/1/38	12 per c.c.	2 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	The total number of organisms present is low and no excremental types are present. From a bacteriological point of view the water is quite satisfactory for drinking purposes.
5073 31/1/38	20 per c.c.	2 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	The bacterial counts are low and the sample contains no excremental organisms or objectionable bacteria. The water is excellent for drinking.
5074 31/1/38	5 per c.c.	Less than 1 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	The bacterial counts are very low and indicate exceptional purity. It is an excellent water for drinking purposes.
18112 4/4/38	1,028 per c.c.	102 per c.c.	Present in 1 c.c.	Present in 10 c.c.	Present in 25 c.c.	From the examination of this sample and data obtained, it will be seen that the water at present in this well contains many excremental organisms and therefore is not in a fit condition for drinking purposes.
18113 4/4/38	390 per c.c.	8 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	No excremental organisms are found in this sample and from a bacteriological point of view the water is suitable for drinking in its present condition. In view of the surroundings it might be considered advisable to see that the well is properly constructed.
22277 30/4/38	19 per c.c.	3 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	The total number of bacteria present is low and no excremental types are found. The results show that the water is quite safe for drinking.
22278 30/4/38	12 per c.c.	9 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 bacterial counts are low and the presence of a few B. Welchii spores is not of serious significance. From a bacteriological point of view the water may be regarded as suitable for drinking purposes.
22279 30/4/38	7 per c.c.	2 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	The total number of bacteria present is very low and no excremental types are found. The result shows that the water is quite safe for drinking.
27203 28/5/38	34 per c.c.	18 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Present in 50 c.c.	In chlorinated river water B. Welchii spores are often present, but in the absence of non-sporing excremental organisms the water can be regarded as suitable for drinking purposes.
38237 2/8/38	38 per ml.	6 per ml.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	The bacterial counts are fairly low and there are no excremental organisms present. From a bacteriological point of view the water is satisfactory for drinking purposes.
38239 3/8/38	43 per ml.	10 per ml.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c	The bacterial counts are not high and there are no excremental types of micro-organisms present. The water is satisfactory for drinking purposes.
52528 31/10/38	6 per ml.	2 per ml.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	The bacterial counts are very low and no excremental types of organisms are present. The water is of excellent quality for drinking purposes.
52529 31/10/38	60 per ml.	5 per ml.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	The agar count at 20°C. is rather higher than usual, but the 37°C. count figure is satisfactory. No organisms of an excremental character are present and the water is safe for drinking purposes.
