R E P O R T .
Bacterially the water at the Headworks is very satisfactory but that of the Service Reser-
voir is not good; it has been of this quality for a long time. The reservoir requires to be
examined when the cause of this deterioration will doubtless be ascertained. The water of
the Distributary System is naturally of the same quality as that of the Reservoir.
Chemically all the water is good.

REPORT.
A sample from the river Penner was available on the present occasion and it affords a
striking contrast in quality to the samples obtained after filtration, The unfiltered water has
all the possible signs of gross pollution, whereas the water after filtration is excellent.
The efficiency of the filtration is also borne out by the chemical results.
Chemical Analysis.
87
REPORT.
All the samples of water taken both at the headworks and distributary system shew an unusually bad
quality probably due to admixture of surface pollution after the recent heavy rains.
Chemically the water is hard, otherwise of fair quality.
Chemical Analysis.

SAMPLE V.
89
REPORT.
The unfiltered water from the river is as usual far from satisfactory bacterially but after
filtration shows a considerable improvement in the way of reduction in number of the organisms
both ordinary and fœcal. This should be considered as highly satisfactory but for the
accidental finding of a pure culture of B. Coli communis in the sample. The water at the
distributary system is of fair quality.
Chemically the water has deteriorated since the previous analysis.

DINDIGUL.
WATER SAMPLES TAKEN—15TH NOVEMBER 1911.
REMARKS.—Water is derived from two sources (1) an infiltration gallery and (2) a deepwell. Deepwell was used as a source of supply
for the last one month. But water from the gallery was allowed to supply the town from 6 A.M. to 10 A.M. on 15th Nov
ember 1911 when samples were collected from the distributary system. The supply is intermittent. There has been
about 7·92 inches of rain since last analysis.

WATER SAMPLES TAKEN—1ST DECEMBER 1911.
REMARKS.—There was a large flow of water in the Samalkota Canal when samples were taken. The canal water was not allowed to
run into the settling taluk. The supply is intermittent. There has been about 13·48 inches of rain since last analysis.

97
REPORT.
There has been a remarkable change in the quality of the water on the present occasion. A gros[ILL]
polluted unfiltered water from the canal has been converted into one of the best when it reaches the distri[ILL]
tary system. Whatever has been done to achieve this should be continued in future.

The water is of uniform fair quality at the headworks but has deteriorated slightly at the
distributary system.
Chemically the water shows a decided improvement over the previous analysis, there being

REPORT.
Bacteriologically the water has considerably improved since the last analysis. The total colonies have
diminished as well as the excremental organisms ; filtration however has not improved it any more than the
Settling Tank and the clearing action of pipes have done.
Chemically also the water shows improvement.
