REPORT.
The water in the lake is not improved by the recent heavy rain but is decidedly inferior in quality to the
sample that was examined. This should not be the case if the catchment area was properly conserved. In other parts of
Presidency the recent rains have had a beneficial effect on the supply in lakes where care is taken with the catchment area.
(ii) The filtered water is very decidedly worse than last quarter. The beds are not removing anything like
quantity of bacilli that they ought to do. The beds themselves have been inoculated with most objectionable
fœcal
when the water was at its worst, immediately after a heavy downpour, and now the sand is adding these organisms
to filtered water though they are disappearing in the lake owing to the action of the sun and to settlement.
(iii) The samples taken from the pipe line are also worse than those of last quarter. The great length of
pipe line acting as a suitable breeding ground for the organisms
The town supply cannot be called satisfactory at this period of the year.
It is imperative that the filters be put into good working order and the useless coarse sand replac ed by fine.
is particularly necessary considering the very unsatisfactory nature of the catchment area and the multiplication of organ
that goes on in the pipes.
The chemical analyses show that the filtered water is harder than the unfiltered; hence it is probable that some
the gravel, pebbles and stones used in the lower layers of the filter beds are limestone and are slowly dissolving in the w
rendering it harder
Recommendations —
(i) That the filter beds be cleaned out and proper materials used in their construction, the sand coming from
sea-shore, where an excellent quality is obtainable.
(ii) That an estimate be drawn up preparatory to acquiring the village in the catchment area

REPORT.
(1) The water in the lake is fairly good ; it contains fœcal bacilli is 3 cc.
(ii) The water after filtration is good, shows no fœcal organisms in 50 cc. The extraordinary variation in the
results obtained from these filters calls for enquiry.
(iii) The three samples taken from the distributary system also show good results.
The water at this time of year is very satisfactory.
Chemically the water is moderate only in quality.

RE PORT.
(i) The water standing over the gallery is not a usual condition ; it is the result of heavy floods. The
contaius fœtal bacilli in 1. cc.
(ii) The water from the gallery is somewhat worse.
(iii)
The samples taken from the pipe supply show fœtal bacilli in 1 cc.
A new gallery is in course of construction. Hence until this is complete it is impossible to give a full report on
water.

REPORT.
The water from above the Infiltration gallery shows considerable amount of pollution. Fœcal bacilli are present,
in 1 cc. The organisms present however are not very objectionable.
2. The sample taken from the infiltration gallery very much resembles the one already described. It contain
fœcal bacilli in 1 cc., the bacilli being much the same.
3. The two samples taken from the hydrants in the town are of almost identical quality with the foregoing.
Chemically the water in the infiltration gallery is a good water.
321
Dind. I.
DINDIGUL.
Samples taken-26th July 1908,
Remarks.--- Water is derived from two sources — (i) an infiltration gallery and (ii) a well near the
station,
Both supplies are now very low and it is with great difficulty that the town can be
supplied.
No rain except some showers, has yet fallen.
