REPORT.
Compared with some past results, the condition of the Vellore water-supply is not at all satisfactory on
this occasion. This is all the more surprising, as there is a good depth of water in the tank and the supply is
constant, while there has been no rain to wash polluting material into the water. In the tank water we find
too many fœcal germs and a surprising variety among them. Filtration has improved the water a great deal
but there are still too many kinds.
It is, however, in the distributary system that the most disquieting symptoms are to be observed. Both
the samples examined are very much worse than the filtered water and show every bad bacteriological feature ;
very high total counts, many fœcal germs with a great variety of species and including members of the susceptible
Class I. It is difficult to imagine any cause for this other than leaky pipes.
Chemically the water is of medium quality, and is improved by filtration. The organic matter is too
high and some at least of it is of animal origin.
