REPORT.
From the bacteriological point of view the Madras water could hardly be in a more satisfactory condition.
There seems to be a definite tendency to improvement which has reached what must almost certainly be a
culminating point on this occasion. Sample I from the Sholavaram channel is not so good as the others but
has been much worse. It shows only one fœcal germ to the cc. and that of a very resistant kind. The.
samples taken from the top and bottom of the Red Hills Lake and that taken at Saidapet toll gate show
no fœcal germs at all. The sample drawn in Malayaperumal street is usually worse than the others, which
seems to require explanation, but though there is no exception to the rule this time the water is still quite
good there. Throughout the total counts are moderately low.
Chemically the water is by no means so good. The amount of organic matter, which appears to be of
animal origin, is far too high astonishingly so considering the bacteriological purity of the water.
prolonged spell of sunshine would appear to have killed off most of the germs associated with this organic
matter, but the situation cannot be regarded as satisfactory or of good augury when the natural purifications
agencies become less effective. The gathering grounds should be better conserved.

REPORT.
On this occasion the water at the headworks is quite good bacterially. Both the spring and the tank
fœcal germs of one highly resistant species. As usual the water is not
good after passing through the filters, though it cannot be said to be bad. As has been frequently pointed
out before the Adōni Water contains so much organic matter that organisms which manage to pass through
the filters can multiply and spoil the water when it is better than usual. The water would require to be
filtered in an exceedingly effective manner, but up to the present there has not been any indication of this
being done. Better conservation of the gathering ground would of course be attacking the evil at its source,
and judging by what is found after good rain, when the ground is well washed, a very considerable
improvement might be expected from such measures. Combining such measures with proper filtration a
very good supply might be got.

REPORT.
The water taken from the river Bugga above the Infiltration Gallery is better than it has
been before at this season and can really be said to be in a quite satisfactory condition, both
bacteriologically and chemically. There is only one fœcal germ to five cc. and this one is of a
variety usually associated with species of Class III. The total count is alsoremarkably low for
a river water. It is a pity to see such a good state of affairs spoiled, but unfortunately this is
what happens almost always at the headworks. The. fœcal germs are five times as many and
belong to a less resistant class. This state of affairs extends all through the system, the samples
being much alike.
Chemically the water is soft and of exceptionally good quality for a river water.

REPORT.
When a water-supply gives such excellent results as does that of Coonoor on this occasion
there is very little to be said about. Extraordinarily low total counts and what may almost be
called a vanishing number of fœcal germs are the satisfactory features we note.
Chemically the water has been better and it must be admitted that the organic matter is on
the high side and is probably of animal origin. This .constituent of the water varies in rather
a remarkable manner both as regards quantity and quality.

REPORT.
From the Bacteriological point of view the water, as distributed to the Town of Madura is,
on this occasion, in very good order. The total counts are low and the number of fœcal germs
almost negligable. This is all the more gratifying as the river water is far from pure, and
demonstrates that the passage, through the infiltration gallery can clear the water almost entirely
of germs.
Chemically the water does not on this occasion show evidence of a double source of supply,
but it is probably all sub-soil water and not river water at all. It is too hard and too saline for a
river water. The organic matter is on the high side and is of animal origin.

REPORT.
The quality of the Bezwada water is not on the upgrade. On each occasion there has been a rise in the
hardness and this time it is a marked one. The water is now half again as hard as it was when first
examined in August. The chlorides and presumably the sulphates are correspondingly increased.
