REPORT.
There has been a marked reduction of the fœcal and other organisms present in the "Jail well" sample
but they belong to many species and indicate a great deal of contamination.
The water from the other two wells shews gross pollution.
Chemically the camp well water is softer than the other two wells.

REPORT.
There is an unsavoury sameness about the results got on analysing the well waters of the Central Jail,
Salem. A grain of comfort may perhaps be extracted from the fact that the results have been worse, but
with huge total counts and great diversity in the species of fœcal germs represented the evidence of
extensive, if not very recent, pollution is complete.
Chemically both waters show a reduction in oxidised nitrogen and in the case of the Hospital well
water this may be regarded as an improvement. in the Kitchen well water a rise in the unoxidised nitrogen
more than neutralises the improvement.

REPORT.
Bacteriologically the well water of the Palamcottah District Jail cannot be classed as good. The total
count, the number and kind of fœcal germs preclude that; but it is satisfactory to note that for two years the
water has been kept free from the highly objectionable recent pollution found at both the examinations in
1909.
If this be due to greater care of the immediate surroundings of the well, the Jail authorities are to be
congratulated on the efficiency of their precautions.
Chemically the water is, as usual, quite fair.

REPORT.
Considering that the river was low when samples were taken, the number of fœcal germs is
di s t i nc t l y hi g h. No mor e ha v e be e n g ot i n t i me s of f l ood. Onl y one of t he mos t r e s i s t a nt k i nds
is present however and this favourable result is also seen in all the other samples drawn from the
system. The water is greatly improved by passage through the infiltration gallery and as
distributed to the town is of very fair quality. The higher total count shown by sample III
is probably due to silt in that part of the pipes.
Chemically the water is also much improved by passing through the gallery, the organic
matter being greatly reduced. The results got are curiously like those obtained at the same
time and under the same conditions at Tanjore. This would seem to point to the possibility o

REPORT.
Tanjore River water appears to be at its best when there is but a small flow of water. On
the present occasion and for a river water it is not at all bad. The total count is quite moderate
and the fœtal germs only one to the cc. and of the most resistant kinds. The water is greatly
improved by passage through the infiltration gallery, both the total count and the intestinal
germs being greatly reduced in number. This favourable state of affairs is maintained in
Sample III, but in Sample IV, we find a notable increase in the total count. Probably there
was some silt in this section of the pipes.
Chemically the water is very fair and the benefit brought about by the filtration is clearly
seen, the considerable amount of organic matter in the river water being partly removed and
partly oxidised.
