ANALYSES OF WELL, SPRING, MINERAL AND ARTESIAN WATERS. 15 
The analysis made, proved the water to be seriously contamin- 
ated, and in its then state totally unfit for human consumption. 
These impurities were without doubt due to the heavy rains, the 
water having run over a large catchment area, the surrounding 
district consisting largely of orchard lands which at stated times 
are manured; the impurities being derived from the fertilizers 
used in enriching the soil. The water was condemned about the 
same time by the Government Analyst, (Mr. W. M. Hamlet, F.1.c, 
F.C.S.) to use his own words—“ The organic, impurity which from 
its character on analysis is probably due to decomposing animal 
matter, is so excessive, and such an amount compels me to con- 
demn this water as being absolutely unfit for human consumption 
either filtered or unfiltered.” The water has lately greatly im- 
proved in quality, but it is not in my opinion a suitable one for a 
town supply, on account of the orchard lands in and around the 
watershed, and if at any time heavy rains are experienced the 
same contamination will occur.
