REPORT.
It is perhaps permissible to extract a grain of comfort from the results on this occasion, in that they
have been worse. Bacteriologically they have however been much better, and it is rather extraordinary that
the results got in 1909 have not been repeated. As usual the old well water is the worse bacteriologically,
while the new well water is the worse chemically. The south gate well water examined at this time last
year was classed in badness along with the old well water, on rather insufficient grounds. Since it is very
definitely the best of the three chemically, it would be well to give it a further trial.

REPORT.
The results given by this sample are not a little extraordinary. It gives such a huge total count that
one would be inclined to regard the water with suspicion, but not one of this huge total is of excremental
origin. Such a very unusual result might have been due to some accident ; so the test was repeated with
double the usual quantity of water. The same result was got ; so we have to note the remarkable fact of the
water of a well whose structure and surroundings are by no means ideal, having no fœcal germs in 160 cc.
From a bacteriological point of view the water is quite safe to drink.
Chemically also the water is by no means bad though the figure for albuminoid ammonia is high, and
curiously high in comparison with that for oxygen absorbed. In this respect only it is inferior to the water
which is usually used, in other respects it is distinctly better.

REPORT.
These Jail waters are rather better than they have been for some time back. The water of the tank
and the tope well must be considered as distinctly good which is a welcome return to what was noticed when.
these analyses were first started. Why the quality of water should vary in such a manner is not by any
means clear. The water from well No. III is the worst, no new position for it to occupy. In comparison
with recent results the total counts are definitely better though the samples from wells IV, III
and I are still
on the high side. All the waters' are definitely soft and free from any objectionable amount of organic matter,
but they all show moderate to high figures for oxidised nitrogen. It would appear from this that laterite is
favourable to purification by chemical agencies, but its filtering power is almost nil.

REPORT.
The water of the Kitchen well is hard put to it to maintain its customary inferiority to that of the
Hospital well, but it may be said to have just done it. Apart from being shown to be contaminated with
organisms usually recognised as pathogenic, the waters are about as bad as they could be.
Chemically they are exceedingly hard and loaded with saline impurities.

REPORT.
Qualitatively the water is better than at the corresponding examination last year and even quantitatively
there is an improvement in the total count. The water is however a very inferior one and it is to be hoped
that something better will be available in the future.

REPORT.
Bacteriologically the water of the general well is on this occasion the worse of the two and shows 100
faecal germs to the cc. as against 10 to the cc. seen in the water of kitchen well. This has not often been
the case of late and may be in relation to the fact that the general well water is now derived from a double
source.
Chemically the water of the kitchen well is as always the worst and shows the same old objectionable
features, Neither of the sources yields at all a good supply and if possible the jail should derive its water
from the municipal supply, which is distinctly good.

Report on the Town Water-Supplies of the Madras Presidency
for the Quarter ending 31st March 1912, being Part I of
Appendix IV to the Annual Report of the King Institute of.

REPORT.
The water-supply of Madura continues to be of satisfactory quality, which is a notable
change from past years. The water as pumped from the Infiltration Gallery is remarkably pure
but even the water in the spring channels cut in the river bed is in good order. Chemically
we have to note the return of the evidence of a double source of supply, as mere passage through
the gallery could not produce such differences as are met with between the two samples. The
water as distributed is also very fair.
