HAVE THEY MISSED the 4th WATER: SOURCE WATER?
IT’S NOT JUST TREATING OUR DRINKING WATER- IT’S CLEANING UP THE SOURCE FIRST!
Surely it’s better, cheaper and safer to concentrate on prevention rather than treatment?
The reports are all about infrastructure, says Victoria University of Wellington Senior Researcher, Dr Mike Joy. However, in the case of drinking water quality, infrastructure to treat water is the ambulance at the bottom of the cliff.
CRUCIAL ‘FOURTH WATER’ MISSING
“I could find no mention of the fence at the top of the cliff, which is protecting water at the catchment scale – i.e. safeguarding the sources of the water. Missing this crucial ‘fourth water’ – the source water – seems odd.”
WATER CATCHMENTS SO IMPORTANT
A water catchment is an area of land and the water that collects and moves through it to drain into a river or stream. A catchment is often bordered by hills or mountains. The water enters via rain or snow and then moves across the surface or beneath the surface (as groundwater) until it drains into a stream or river.
“I note that the summary report on the workshops held for the Three Waters Reform Programme, released in March 2021, showed that in polls held during the workshop, taking a catchment view of water ranked as the second most important objective by attendees.
NITROGEN & NITRATES CAUSE CANCER
“Finally, I could find no mention of one of the emerging issues for New Zealand, that is nitrogen contamination of drinking water. There was no mention of it, nor just how expensive it is to remove nitrate from water,” concludes Joy.
