Trout and Rivers Advocacy Urges Rural NZ to Test Water Supplies


All rural households that rely on their own water supplies should get them tested for nitrate levels if that water flows through agricultural land says NZ Federation of Freshwater Anglers (NZFFA) spokesman Steve Gerard of Rakaia Gorge.

His call came following nitrate level testing of waters by NZFFA around Canterbury and in particular the water supplying his own household. Gerard said he took advantage to the NZFFA’s water testing service to have his family’s own water supply tested. The results were alarming. The sparkling spring fed stream at the top of the Canterbury Plains tested 5.0mgl for nitrate, while a nearby house spring water supply has tested consistently at 8.0mgl. 

“I never suspected our lovely spring water could possible test so high, considering our location high up on the plains in Rakaia Gorge,” he explained.

Gerard said there were a couple of dairy farms upstream of the household.

“Whether that is the cause or something else I don’t know. However, the possible health impact at 8.0mlg is concerning for our family, and as an interim measure, we are sourcing our drinking water from the town supply” he said. 

Overseas studies have shown a strong link between high nitrate levels in drinking water and bowel cancer in humans. Bowel cancer is the second-highest cause of cancer death in New Zealand while a 2018 Danish study of 2.7 million people has shown a strong link between nitrate levels and the disease. In addition, high nitrate levels in water have a link to human birth problems such as underweight and premature babies.

“New Zealand has one of the highest bowel cancer rates in the world. Recent data show also that drinking water supplies in some parts of New Zealand have nitrate levels more than three times higher than the threshold level for colorectal cancer risk identified in the Danish study,” explained Gerard.

  

He reiterated all rural households that rely on their own water supplies should get testing particularly if that water flows through agricultural land.

    Environment Canterbury consents the use and pollution of freshwater for the gain of agribusinesses while distancing itself from the costs &/or consequences to the affected downstream well owner, the environment, and recreational water users. Perhaps Ecan’s performance should be judged by different measures than the volume of consents it approves. (The justification for government appointed commissioners in 2010).
