REPORT.
The sample taken from the infiltration gallery shows faecal organisms in -10 cc. The .
organisms; show no very objectionable ones amongst them.
The samples taken from the distributary system show improvement on this result though in
both instances objectionable organisms are to be found.
The sample taken from the well shows faecal organism in 1 cc., the organism being those
found in wells in hot weather.
Chemically the water from the gallery and the well are good, but both are very hard.
The recent rains probably have caused a temporary deterioration in the quality of the water.

REPORT.
The sample taken from the river shows fœcal organisms in . 01 cc. It is highly contami-
nated, due to the recent rains in the hills and the floods. The organisms present are not
however very objectionable.
The sample taken from the first tap after the water is drawn from the gallery shows fœcal
organisms in .1
cc. The organisms isolated are harmless in themselves and are much too
numerous.
Two samples from the distributary system show organisms in 1 and
.1 cc. and in one
instance, namely, that in the Teppakulam, objectionable bacilli are present.
Chemically the water from the river is full of silt and contains a lot of organic matter,
but that from the gallery is of fair quality and much improved on the raw river water. The
deterioration in the quality of the water at this time of the year can only be accounted for by the
recent rains bringing down a large quantity of pollution, some of which finds its way into the
gallery. Probably as the flood water decreases in amount the quality will rapidly improve.

REPORT.
The sample of water taken from the above gallery and from the suction well shows fœcal
organisms in 100th of a cc. The bacilli present are however not very objectionable.
The sample of water taken from the southernmost corner shows no organisms in 50 cc.
This is due to the action in the pipes.
The sample taken from the northernmost corner shows some improvement though nothing
like as much as the latter.
Chemically the water may be classed as of good quality.

REPORT.
The sample taken from the spring contains organisms in 5 cc.
The sample taken from the lake contains very large number of organisms. namely. 100 per cc.
The organisms however show that the water has been thoroughly well sunned.
The sample taken from the filtered reservoir shows for the first time that the filter beds are
considerably improving the quality of the water. Further improvement has gone on in the pipes
so that the water from the hydrant is of good quality and contains only one organism in 20 or
30 cc.
Chemically the water is not a good one, both ammonia figures being extremely high and
both being considerably increased by the action of the filters. Explanation for this phenomena
is not very apparent.

REPORT.
The sample from the storage reservoir is of fair quality, fœcal bacilli being present in 5 cc,
Organisms are not objectionable in themselves.
Sample B from Service Reservoir—the same remarks apply.
Samples C and D from distributary system contain water of the same quality, namely, fœcal
organisms in 5 cc.
Chemically the water is a good one and is very soft.

REPORT.
The sample taken from the Vagavati spring shows large amount of fœcal contamination.
The sample from the Suction well shows that the water taken at the depth of the gallery is
pure. Fœcal organisms are present only in 20 cc. and they are not objectionable in themselves
The quality of the water taken from the hydrants is about the same.
Chemically the water from the gallery is a good one.
