REPORT.
The water of the Sholavaram Channel has been worse than on the present occasion, but it is far
f r o m b e i n g s a t i s f a c t o r y . T h e r e a r e t o o m a n y f œ c a l g e r m s a n d t o o m a n y k i n d s . T h i s i s h a r d l y w h a t w e s h o u l d
expect after a prolonged spell of dry weather. The samples from the surface and the bottom of the Red Hills
Lake show progressive improvement, and the latter is very good indeed. The water has deteriorated and its
passage to the city and in Malaya Perumal Street is very similar to the surface water of the Red Hills Lake.
The sample taken at the Saidapet toll gate shows a strange state of affairs. There are fewer fœcal germs
but all belong to the susceptible Class I, and to varieties not present in any of the other samples. The water
at this place has, as a rule, been as good or better than that at other parts of the system, so it is surprising to
find on this occasion evidence of recent pollution. It is to be hoped that the cause was a temporary one.
Chemically the water is far from satisfactory. There are present all the signs of recent pollution with
organic matter of animal origin. High chlorine, albuminoid nitrogen and absorbed oxygen with an undesir-
able ratio of four to one between the last two. This seems to point to a dirty unconserved state of the
gathering grounds.

REPORT.
The water from Storage Reservoir is on this occasion in a highly satisfactory state, and is better than
ever before since this system of analyses was started. With only one fœcal germ in 20 cc., and only one
fairly resistant species present there is very little left to be desired.
The water in the Service Reservoir is not nearly so good, there being twenty times as many fœcal germs
and a greater admixture of species as in the previous sample. Deterioration of the water in its passage from
the Storage to the Service Reservoir is not a new feature.
The samples taken from the distributary system are both good. They are markedly better than the
sample from the Service Reservoir. The sample taken in front of the Post office shows too great a number of
varieties. In this respect the sample taken from the Choultry near the Railway Station is the better. This
sample shows a very marked improvement over what was found on the two previous occasions.
Chemically the water is as usual excellent. No stress can be laid on the figure for albuminoid nitrogen
as it must certainly be due to an error in techniques.

REPORT.
The water from the spring and the filter beds shows a marked improvent this quarter, fœcal organisms
only being present in 5 cc. and upwards ; the bacilli are of the resistant class. The water from the reservoir
and distributary system show evidence of gross animal pollution, for fœcal organisms are present in a tenth
of a cc. and they are of many varieties. The water from the fountain No. 12 is the worst in this respect
as the analysis suggests recent pollution. I would suggest that in this case there is some leakage in the
pipe system. The chemical analysis of the waters shows very little change from the previous quarter.

REPORT.
The analysis of the sample of the Pennar river this quarter shows gross contamination, there being fœoal
organisms in a hundredth of a cc. As compared with the analysis of last quarter this is not satisfactory.
The filtered water is certainly better than that of the river, but here again there are fœcal organisms in 5 cc.
and upwards The water from the distributary system keeps much about the same as the filtered water
so that the pipes are probably fairly clean.
h emically the river water contains more saline matter than on the last occasion.
