REPORT.
The water of the Adóni supply has undergone a remarkable change which is most probably due to the
heavy rainfall. In all the previous analyses of this water an undesirably high figure for organic matter was
,shown. On the present occasion it is very much lower, only one-fifth of what it was at this time last year.
Unfortunately this improvement does not extend to the bacterial content of the water. This is not very bad.
however and the varieties of fœcal germs present are not objectionable in themselves. The total count is too
high.
The samples from the distributary system show greatly decreased total counts, but this improvement is
more than neutralised by the presence of vibrios in the water. The source of these highly objectionable
organisms should be most carefully inquired into, and the necessary action taken to exclude them in future.

WATER SAMPLES TAKEN—15TH OCTOBER 1910.
REMARKS.—The tank water was not used as a source of supply when samples were taken as there was an abundant yield from the
spring. The tank is full and overflowing. The supply is constant. There has been about 27·37 inches of rain since last analysis.
