REPORT .
The water from both the Tanjore Jail wells is probably derived from the same source, and, as has been
previously noted, that source is not a very desirable one. On the present occasion the water of both wells
show the high number of the hundred fœcal germs to the cc. It is true indeed that the species represented
are not in themselves objectionable, there being no evidence of recent pollution. This is borne out by the
results of the chemical examination. Here we see the usual remarkably high figure for oxidised nitrogen, a
well-known sign for old pollution. The small amount of organic matter left unoxidised is of animal origin.
Otherwise the results are fair enough. With one exception during a specially high flood, the filtered water of
the Tanjore municipal supply has been notably better than the water of these wells.
