REPORT.
The result got with the samples on this occasion are very fair ; better than they have been for the last two
years, and considerably better than they were at this season last year. Notably there is the absence of vibrios,
and fewer excremental germs in the water at the headworks.
Chemically the water is quite fair. There is a tendency for the organic matter to vary in quality, and
this seems to be in association with the rainfall. When there is a flow in the river the albuminoid ammonia
is higher and the oxidised nitrogen lower in proportion; after a spell of dry weather the reverse holds good.
