REPORT.
The water seems to be of uniform quality throughout the system; filtration does not improve
it. Chemically a marked deterioration of the water has been noticed since last year probably
due to the occurrence of a severe drought.

REPORT.
The results of Bacteriological analysis of the samples are worse during this quarter than
those of the last occasion. There is more than tenfold increase in the total count and fivefold
in the excremental organisms. Filtration has not so far been effective. The quality of water
supplied is thus on the retrograde step. It was good in March, medium in June and bad in
September. This requires some investigation.
Chemically the water continues to be good.

The Red Hills Lake water is at its best on the present occasion. ; one of the lake samples does not
contain even a single fœcal organism in about 2 ounces of water. The total counts are also low.
Chemically there has been a slight improvement in the sample taken at the distributary system.

REPORT.
The river water has improved in quality since last analysis, but still shows sufficient signs
of pollution as to place it in the class of bad waters. Filtration has been efficient remarkably
removing all the excremental organisms, quite a unique example since the commencement of the
present system of analysis. This state also obtains in the distributary system.
Chemically the water is of fair quality and much improved after passing through the
Infiltration Gallery.

REPORT.
The river water continues to be bad, but filtration has decidedly improved it, there having
been a decided reduction in the total organisms present as well as the excremental forms. Of
the samples taken at the distributary system, that from the Municipal Office is highly polluted.
This condition has been noted on several previous occasions pointing to serious leakage in that
section of the pipes.
Chemically, excepting for a slight increase in total solids, the water continues to be good.

REPORT.
All
the samples show a certain amount of deterioration since the last analysis. There has been about
five-fold increase in the total number of organisms of ordinary and excremental nature, present in a cubic
centimeter. This condition is probably due to the continuous drought in the locality.
Chemically the water is of fair quality throughout.
