REPORT.
Considering the high flood that there was in the river when the samples were drawn it is surprising to
find so few fœcal germs present, the more so as the varieties are numerous and of a distinctly undesirable
description. Pollution has been extensive and fairly recent, though it is probable that the drainage area is
getting cleansed.
After passing through the infiltration gallery the water is very greatly improved and
state of affairs is maintained throughout the system.
Chemically the river water, as was to be expected is not good, but most of the organic matter being in
suspension has been removed by passage through the infiltration gallery leaving an excellent product.

REPORT .
The Madras water-supply is in better condition than it was in at the corresponding season of last year.
The water in the Sholavaram channel is notably better in the matter of total count and in the number of
f o e c a l o r g a n i s m s a n d i n t h e i r n a t u r e .
The sample taken from the bottom of the lake is of course polluted with sediment and little stress need be
laid upon it. All the foecal organisms are of the second or moderately resistant class. Class I has presuma-
bly succumbed to what sunshine there was, and under normal sunny conditions Class II would also probably
be killed off.
The surface water of the lake is exceedingly pure and shows only a very few foetal organisms of the most
resistant kinds. The samples drawn from the distributory system are also good, but not so pure as is the lake
water. Chemically the water contains too much organic matter, and this appears to be mainly of animal origin,
not a good testimony for the way the gathering ground is conserved.

REPORT.
It must be admitted that for a river in flood the water is not at all bad. The same thing was noticed
last year at this season when there were even fewer fœcal germs, but a higher total count. Sample No. II
shows an extraordinary change for the worse, and the cause of this should be looked into. The great number
of varieties of fœcal germs present points to the water having been extensively polluted.
Sample No. III is somewhat better again but the total count has gone still farther up. The section of
the pipe line to the Geddy Bazaar Road has an unenviable capacity for adding excremental germs to the
water. On the present occasion there are a hundred times as many fœcal germs as the river water contains.
They all belong to one or two varieties which seems to point to the pipe containing silt.
Chemically the water is a good one. The figure for nitric nitrogen is higher than it was at this
time last year. This figure is liable to rather remarkable fluctuations.

REPORT.
On the present occasion samples were not collected from the source and headworks, but only from the
distributary system. There does not however seem to be any reason to suppose that there is much divergence
from past findings. A good to fair supply spoiled in distribution sums up the situation pretty fairly. In the
main such have been the results shown ever since these analyses were started. On the present occasion all the
samples show fœcal bacilli in one-tenth of a cc and all contain vibrios. Fountain No. 12 in the Old Madras
Road maintains its reputation for high total counts.
Chemically the water is as usual. Moderately hard with some soluble sulphate, but otherwise fair.

REPORT.
In some respects the results got this quarter with the Bezwada water are even better than last. The
water near the headworks is not so good, but pipe action has had a very marked effect on the germ content
of the water. It seems to have a selective destructive effect on germs of animal origin but none on other sorts.
These latter appear to collect in the pipes and get added to the, in this respect, better water of the headworks
raising the total counts enormously.
Chemically the water is, as in last quarter, rather hard but otherwise excellent.
