Arsenic reading of 0.005mg/L recorded last 3 months at Victoria Avenue Water Treatment Plant



Last week we brought you the story regarding the low levels of arsenic in the Waiuku drinking water. While nothing has changed, we investigated arsenic and water testing further. The results are still at 50 percent below the maximum acceptable level of 0.01mg/L, as defined in the Drinking Water Standards of New Zealand.

Arsenic is a metal that has no smell or taste. Arsenic is naturally present in bedrock in many places. Depending on local environmental conditions, arsenic can leach from soils or mineral deposits into groundwater.
When looking at some research regarding the effects of living in an area where high levels of arsenic were present, people were more likely to have bladder, lung, or skin cancer.
They were are also more likely to have problems with their skin, and with their cardiovascular, immune and neurological systems.
WaterCare in accordance with Ministry of Health guidelines have increased the testing frequency to monthly. This is a requirement when a reading at or above 50 percent of the PMAV is recorded.
Watercare General Manager Service Delivery, Shayne Cunis, says the Auckland Regional Public Health Service and the Medical Officer of Health have been notified.
“We are following normal processes by increasing our sampling and analysis programme in Waiuku. While detection is below the limit specified in the Drinking Water Standards of New Zealand, we are evaluating additional treatment options.”

Since you’re here… we have a small favour to ask. More and more people want the Post than ever but advertising revenues across the media are falling fast.

The Post’s independent, investigative journalism takes a lot of time, money and hard work to produce. With investigative reporting, we often don't know at the beginning how a story will unfold and how long it might take to uncover. This can mean it is costly – particularly as we often face legal threats that attempt to stop our reporting. But we remain committed to raising important questions and exposing wrongdoing. And we do it because we believe our perspective matters – because it might well be your perspective, too. If everyone who reads our reporting, who likes it, helps to support it, our future would be much more secure. For as little as NZ$5, you can support the Post – and it only takes a minute. Thank you.
