REPORT.
Bacteriologically the analysis of the pump well water shows considerable improvement; the quarantine
well water has however deteriorated and suggests some recent excremental pollution.
Chemically except for the usual high figure for oxidized nitrogen there is nothing particular to point
out; the result of the analysis is much the same as that of the last quarter.

REPORT.
Bacteriologically the sample of the old well water shows the usual amount of pollution , excremental
organisms are present in one hundredth of a cubic centimeter and the total count is high. The new well has
improved a little since the last analysis but there should not be much variation in a well water.
Chemically both the waters contain a large amount of solids.

Bacteriologically both the well and reservoir samples are of the same quality but the well shows a decided
improvement since the previous analysis. The river water shows highly suspicious signs of animal pollution
it contains about 100 organisms in 1 cc., the total count also being high.
Chemically the reservoir sample is not good; it shows an increased amount of albuminoid nitrogen and
low ratio between it and the oxygen absorbed; the same may be said about the river sample.

Bacteriologically the total number of organisms continues high and the fœcal germs though belonging to
class II. are more numerous than in the last half-year' s analysis.
Chemically the water is about the same as before, rather hard but of a fair quality.

REPORT.
• •
This water as usual shows a very high total count, but a slight improvement in the number of excremental
organisms present.
Chemically the water is very hard and it is therefore not at all a suitable drinking water.

REPORT.
The water from Well No. 1 is of a much bettor quality than during the last half year showing a much
lower total count and only one fœcal germ in 10 cc. which belongs to the more resistant class.
The sample from Well No. 2 also shows an improvement with a slightly lower total count and a great
reduction in the number of fœcal germs.
Well No: 3 shows signs of considerable excremental pollution containing as many as 100 fœcal, organisms
in one cc. belonging to not less than. seven different varieties the total count is also high.
Water from Well No. 4 and the tank do not call for any special comment, but the Tope well water show
a marked deterioration, the total organisms being countless and the fœcal germs being 500 times more
numerous than on the last occasion and belonging to at least five different varieties.
The chemical analysis of the samples does not call for any special remarks the waters being on the whole
of the same salinity, softness and organic purity as before.
