REPORT.
On this occasion no sample of the unfiltered water was taken which is a pity as, on the last examina-
tion, it was the best of the lot and had suffered deterioration by its passage through the filters and
p i p e s . T h e w a t e r t a k e n f r o m t h e s u c t i o n w e l l o f t h e i n f i l t r a t i o n g a l l e r y s h o w s a v e r y u n s a t i s f a c t o r y
state of affairs. All the points alluded to last time as requiring amendment are present in even greater
degree, and there are some objectionable features in addition. We have a huge total count, fœcal germs
in one tenth of a cc., many varieties represented and these including some of Class I which points to recent
and therefore dangerous pollution getting access to the water. If this pollution is being derived from the
f i l t r a t i o n p a s s a g e s i t o u g h t t o b e s e e n t o a t o n c e . T h e w a t e r f r o m t h e d i s t r i b u t a r y s y s t e m i s r a t h e r
better on this occasion, though it also is capable of improvement. There are too many varieties of
excremental germs in the water from the Geddy Bazzar Road, though these are probably unobjectionable
in themselves. The water from the tap in Yerramukkupalli is definitely better in this respect.
Chemically the water is as before and that was excellent. It is a pity that such good water should
be polluted in the above manner, and the circumstance is suggestive of bad management.
