REPORT.
From every point of view except that of being in a condition to cause epidemic disease these waters
very bad. They show a very high total count and they have germs of animal origin in one-tenth and or
hundredth of a cc. respectively. Among these latter too there are so many varieties as to indicate extensive
if old-standing, pollution. This is also borne out by the results of the chemical analyses, which show very his
figures for oxidised nitrogen and for chlorine. The great hardness of the waters and also their considers;
contents of soluble sulphate would render them liable to set up disturbances of the digestive system.

REPORT.
Bacteriologically the main objection to both these waters is the high total count so high that it could
not be enumerated. As regards germs of animal origin, however, the waters are much more satisfactory
with one to the cc. in the case of the jail well and one to five ccs. in the camp well. The varieties present
all belong to the more resistant classes which indicate that a considerable amount of natural purification
has gone on.
Chemically the water of the camp well is the better in spite of its having more total solids and soluble
sulphates. The jail well water is more saline, it has a. suspiciously high figure for nitric nitrogen, and
ratio, one to five, between albuminoid nitrogen and absorbed oxygen indicates that pollution of anmal
origin has access to the water. There is. however, nothing to show that recent pollution has taken place.

REPORT.
The sample from the suction well shows fœcal bacilli in 1 cc. The organisms are not in
themselves objectionable but are too numerous.
2. The sample taken from the reservoir shows fœcal bacilli in 1 cc. The increase is,
probably due to settlement of organisms in the tank.
3. The sample taken from near the Muhammadan School and from Punganur Amman Koil'
Street are much of the same quality. The organisms present suggest either silt or leaks in the
pipes. They are inferior to the original sample.
4. Chemically the water is of a fair quality but rather hard and contains much saline
matter. The nitrates are present.

REPORT.
The sample taken from the lake shows fœcal bacilli in 1 cc., but the organisms sh ow that
the water has been thoroughly well sunned and settled.
The sample taken immediately after filtration shows no improvement of the water, the
filter beds not affecting the number of organisms present in any way.
Two samples taken from the distributary system, east and west of the station, show that
remarkable improvement has gone on as the water passes through the pipes. No fœcal bacilli
are found in 50 cc.
Chemically the water is of good quality.

The sample from the river bed shows fœcal bacilli in 1 cc., the organisms presenting the
typical mixture of recent and dangerous pollution.
The water from the infiltration gallery is much improved. Fœcal organisms are present in
20 cc. and are not objectionable.
The quality of the water distributed from the hydrants is quite satisfactory. Slight
improvement has gone on owing to the action of the pipes.
The river water, filtered water and four samples from hydrants have been carefully examined
for cholera vibrios as the disease is rather prevalent in the .town. All these have given a
negative result showing that the town water-supply is not in any way responsible for the
presence of the malady.
Chemically the river water shows signs of pollution and that of the gallery may be described
as of a fair quality.

REPORT'
The sample from river bed contains fœcal bacilli in 1 cc' The organisms present are not
very objectionable in themselves.
The sample from a tap immediately after filtration shows organisms present in 5 cc.
The samples taken from the distributary system show further improvement due to action of
pipe' The one from Kodaikal Street shows fœcal bacilli in 20 cc' and that taken from the
hydrant outside the station shows in 10 cc'
Chemically the water from the infiltration gallery is almost a good. water. It is however
rather hard for river water.
