REPORT.
The results on this occasion show a reversal from the usual in respect of the storage and service
reservoir s , the latter being considerably better, and really in a very satisfactory condition. Is there any
reason why this state of affairs, in regard to the service reservoir of course, should not be maintained. The
water of the storage reservoir is not nearly so good as it has been, but this may be associated with recent
rainy weather. There are ten fœcal germs to the cc.. and nine of the ten colonies subjected to closer scrutiny
proved to belong-to a species whose resistance to the natural purification processes has not been determined.
This is unfortunate, but as this germ both in. Sample I and Sample III is associated with moderately and
very resistant species, it is more likely to belong to Class II or Class III than to Class I.
Sample III from the fountain in front of the Telegraph Office is more like the storage reservoir.
Possibly there is silt in this section of the pipes.
Sample IV is better again though not so good as the water of the Service Reservoir.
Chemically the water is as usual excellent.

REPORT.
The river water is exceedingly impure, showing a huge total count and a hundred fœcal organisms to
the cc. These latter however are not very objectionable in themselves, rendering it probable that the more
dangerous varieties of the pollution reaching the river have been got rid of. From sample we find that
nine-tenths of the bacterial impurities have disappeared, so that the infiltration gallery is working well.
Sample II shows still farther improvement as regards the number of fœcal germs and from this point of
view is of exceptional purity. The admixture of varieties and the total count do not indicate such a satis-
factory state of affairs. Taken all round the sample drawn from the Pillar Fountain near Big Teppakulam
Fountain is the most satisfactory, the total count being largely reduced and the fœcal germs, though increased
as compared to sample III, b e l o n g i n g t o o n e s p e c i e s o f t h e m o s t h i g h l y r e s i s t a n t c l a s s .
Chemically the water shows similar features to those observed formerly. The increase in hardness and
salinity of the gallery water over that of the river water indicates some admixture with water From another
source. This has been noted before, but on this occasion the admixture is not responsible for additional
impurity. As regards organic matter the filtered water is very fair.

REPORT.
Sample No. I from the collecting well of the infiltration gallery is pretty good. There are few fœcal
germs and though too many species are represented they are mostly of the more resistant kind, and indicate
a
more satisfactory condition of the water than in. January 1.909, for instance, when the fæcal gems were still
fewer. The water has as usual a high degree of temporary hardness but is otherwise good.
Samples II and III may be taken together. Bacteriologically they are of much the same quality.
They have many more fœcal germs than were seen in sample I ; but only the more resistant kinds are
present. The water is softer.
Bacteriologically sample IV resembles sample I, chemically it is more like sample II. It is probably
mainly well water altered by passage through the pipes.
A special feature in all the samples on this occasion is the low total counts.

REPORT.
The results got at Nellore on this occasion are not easy to explain. As was the case last year the river
was in flood, so that not much is to be expected from the river water. Sample II from the head water works
shows an extraordinary drop in the number of fœcal germs but nothing like so great a drop in the total count.
We hardly expect to find a filter or a gallery acting in a selective manner. Sample III is worse than the raw
water of the flooded river and is very bad indeed. Sample IV is again .like the water from the head works.
Chemically the water as distributed is considerably harder and more saline than the river water. This
suggests an admixture with water from some source other than the river, which might account for the
variation in the bacteriological finding between Samples I and II. These chemical increases have been more
or less in evidence on most of the occasions when this system has been examined.
