REPORT.
There has been a considerable falling off in the quality of Tirupati water, both in comparison with the
last occasion it was examined and with the corresponding period of last year. There does not seem to be any
variation in the meteorological conditions to account for this. As usual the water of the east well is better
than that of the west well. The experimental well which is now examined for the first time yields worse
water than either, though it is not very much worse than the west well water. It seems a pity that more
water of the quality shown by that of the east well should not be obtainable. All the samples taken at the
headworks show undesirably high total counts. The water as distributed is unfortunately more like that of
the west well but shows even higher total counts and this is specially seen in the water from Fountain No. 57
in Bari Street where the water is worse than that of the experimental well. The pipes and especially the
Bari Street Section must be dirty or leaky.
Chemically the water shows a good deal of oxidised nitrogen, and though rather hard is otherwise fair.
