REPORT.
The sample from the supply channel to Sholavaram lake shows fœcal organisms in 1 cc. The organisms
a r e n o t e x t r e m e l y o b j e c t i o n a b l e .
Chemically the water contains rather large amount of chlorine.
The sample from the channel connecting with the Red Hills lake—Very much the same remarks apply
above.
Chemically the water is considerably worse than the preceding sample.
The sample from the Red Hills lake—Organisms are present in 1 cc. They are not objectionable in
teniselves.
Chemically the water contains large quantities of albuminoid nitrogen and free ammonia.
The samples taken from the distributary system show an improvement on the last result. The organisms
are present in 5 cc.
r4
Chemically also the water is slightly improved.

REPORT.
The sample of water from the spring contains fœcal organisms in 1 cc. Those that are
present are very objectionable and suggest serious pollution.
The water after filtration shows little or no improvement. The organisms present seem
less objectionable.
Other samples from the reservoir and the distributary system cannot be looked upon as
satisfactory. Fœcal organisms are present in 1 cc. and those isolated are highly objectionable
and suggest fœcal pollution of the dangerous nature.
Chemically the water is not a bad one.

REPORT.
The sample from the river Pennar shows considerable amount of pollution but the organisms present are
not very objectionable.
The sample taken from the gallery shows fœcal organisms in 5 cc.
The two samples taken from the distributary system show fœcal organisms in 5cc ; but in both instances
highly objectionable organisms are found. This is most unusual in Nellore and suggests that silt may be
accumulated in the pipes.
Chemically the gallery water is good but contains a very large quantity of chlorine. The river water
show sample evidence of gross

REPORT OF WELLS.
The sample from the well opposite the Post Office shows very gross contamination, fœcal organisms being
present in 1/100th of a cc.
The sample from the well by the side of Kalasa Mahal is slightly better, fœcal organisms being present in
.1cc. The organisms that are present are not extremely objectionable.
Chemically the water from the well opposite the Post Office is a good one and does not show much
pollution . The well by the side of Kalasa Mahal however is a bad water showing considerable organic

The samples taken from the two wells on the bank of Kalyani River show considerable pollution, fœca
bacilli being present in .1 and 01 cc. The organisms though very numerous do not suggest recent pollution
The samples taken from the distributary system show considerable improvement, fœcal organisms being
present only in 1 cc.
Chemically the water is good one. The only feature to be noticed is that of the two wells, the easter
one is very much softer than the one at the west end of the gallery, the eastern one being nearer a stream.
