REPORT

       Ādōni water is always characterised by the large amount of organic matter it contains. This organic
matter varies a good deal both as regards quantity and quality. On the present occasion it shows the high
nitrogen carbon ratio associated with animal organic matter. Bacteriologically the water is not at all bad, but
the water in passing through the pipes acquires high total counts that were absent from the water at the
headworks; this is a very usual state of affairs at Adoni.
