MADRAS.
WATER SAMPLES TAKEN—16TH & 17TH JANUARY 1912.
REMARKS.—The Maclean's Channel was dry. There was no flow of water from the Shola-
varam Channel to the Red Hills, when samples were taken. The supply is
constant. There has been about 2304 inches of rain since last analysis.

REPORT.
Although not so good. as last year at this season, the results got the present occasion cannot be called bad
The water of the Sholavaram Channel is the worst both from the point of excremental pollution and of tot
count. The lake water is quite good with a lower total count on the surface than at the bottom which is much
what we would expect in sunny weather. There is a tendency for the water in the Distributary System to b
not quite so good, but there is not much to complain of this time.
Chemically there is more organic matter in the lake water than in that of the supply channels and thi
has frequently been the case before.

REPORT.
There is nothing new to be said of the Guntur water. A. really good water is more or less
spoiled by its passage through the service reservoir and pipes. Results such as these do not
recur year after year without some cause, probably readily ascertainable, for them. It is time
the authorities concerned took some action in the matter. Chemically the water is on the hard
side and contains a good deal of total solids not accounted for by the substances estimated

REPORT.
The results got on analysing the Bezwada samples are rather apt to be surprising. In the present case
we have excremental organisms in extremely small amount, but of the worst possible type. The phenome
-
nally low total counts seem to preclude any idea of extensive leaking in the pipes, but possible high negative
pressures may be established in the pipes as a result of the intermittent service, and such would severely test
the joints of really well laid pipes. Chemically the water is fair, the large proportion of the organic matter
having been rendered innocuous by oxidation. The tendency for the hardness to increase is no longer in
evidence.

REPORT.
It would appear that the Infiltration Gallery is working with fair efficiency as we note
a large reduction of the fœceal germs in the water after passing through it. The post filtration
pipes are however dirty and we get very high total counts. The section of pipe near the
Railway station is worst as in addition to the high total count the foecal germs are brought up
to the same figure as that shown by the river water, and the kinds are more numerous and more
objectionable. With a constant supply available the pipes should be more frequently scoured out.
Chemically the water as distributed is quite good.

REPORT.
It is satisfactory to see that the anticipations expressed by the Municipal Chairman,
T anjore, in his note of the 17th January 1912, regarding the poor resulte got with samples of
Tanjore water in previous quarters, have been fully realised. The raw river water shows a
m oderate amount of pollution and a high total count, but the action of the re-laid filter beds is
exceedingly good and a water of excellent quality is distributed to the town. Chemically also
the water shows benefit from filtration in the marked reduction of organic matter.

REPORT
Adoni water is always characterised by the large amount of organic matter it contains. This organic
matter varies a good deal both as regards quantity and quality. On the present occasion it shows the high
nitrogen carbon ratio associated with animal organic matter. Bacteriologically the water is not at all bad, but
the water in passing through the pipes acquires high total counts that were absent from the water at the
headworks ; this is a very usual state of affairs at Adoni.

CUDDAPAH.
WATER SAMPLES TAKEN—18TH FEBRUARY 1912.
REMARKS.—The Bugga river was dry when samples were taken. There was no water over the
gallery. The water from the experimental well was pumped into the service
reservoir to supply the town from 10th January 1912. The sample from the tap
adjoining the service reservoir was not taken as there was no flow of water
through the tap owing to the low level of water in the reservoir. The level of
water in the reservoir was about 8 inches. The supply is intermittent. There
has 'been about 2.30 inches of rain since last analysis.

REPORT.
For some time back the Cuddapah water has shown a moderately high figure for nitric nitrogen,
indicative of pollution of old standing. This first appeared in 1910, but now the water has reverted to its
older condition and is really remarkably good.
Bacteriologically the state of affairs is not quite so satisfactory though it is not bad. No sample could
be obtained from the head works as the level was too low. The sample from Yerramukkuppalli shows a very
high total count and there is probably silt in this section of the pipes. The sample taken from a tap in the
Madras road is much better and can be called quite satisfactory.

REPORT.
The water at the headworks is not good on this occasion and forms a sad contrast to the state of affairs
this time last year. Exceptionally too the water from the Collecting Chamber is not so good as that from
the wells. As usual the water distributed is much worse than that at headwords, but it seems rather useless
proceeding to go on pointing this out time after time. Chemically the water is quite fair. That from the
west well is the harder. The water as distributed seems to he a fairly even mixture of these two.
