REPORT.
Little need be said as to the canal water. The canal being flooded it is not surprising to find almost every
type of bacterial impurity well represented. The contrast between this and the water of the Northern Settling
Tank is extremely marked and shows what a valuable procedure simple settling can be. Sample III from the
Southern Settling Tank is just like the canal water, presumably it has just been pumped in when the sample
was drawn. Sample IV shows that the filtered water is very much worse than the water that has merely been
allowed to settle. This is not an unusual feature The samples taken from the distributary system are
much better, especially Samples V and VI. As regards fœcal germs Sample VII is also quite good, but it
has managed to acquire a huge total count. It would be interesting to find out where these organisms have
come from.
Chemically the water is quite good.
