ORC reducing Shotover wastewater testing despite contamination spike
The results, which come from the Otago Regional Council's own monitoring page, showed E. coli levels spiking above minimum acceptable standards about July 28, while there have also been breaches of compliance for suspended solids on at least three occasions in the past month.
From August 18, instead of testing weekly and having weekly site visits, the ORC will shift to monthly testing and visits, although there will still be weekly water testing of the Kawarau River downstream of the treatment plant site.
An ORC spokesman said in a media release this decision balanced the need to ensure a robust monitoring programme which provided assurance to the people of Queenstown and downstream from the discharge, "with the need to ensure prudent financial management, where appropriate monitoring and oversight is already in place".
The spokesman said it had confidence in Queenstown's own monitoring of the site, as ORC would audit it for any discrepancies or breaches.
"With the enforcement order in place, as well as the monitoring required under the resource consent, Queenstown are now required to undertake a wide range of monitoring and supply these results to ORC."
The Shotover wastewater plant has been beset with compliance problems for several years.
In January, the regional council sought an enforcement order from the Environment Court to address current compliance issues at the treatment plant, which followed the issuing of two abatement notices and 10 infringement notices.
On June 9, the Environment Court approved the application for an enforcement order, which requires the Queenstown Lakes District Council to undertake several actions aimed at achieving compliance on site — most of them to do with frequent monitoring of the water quality.
All test results will continue to be made public.
The ORC declined to respond to a series of questions before yesterday's deadline.

ORC reducing Shotover wastewater testing despite contamination spike
The regional council is dialling back its regular testing of the Shotover wastewater treatment plant despite E. coli levels spiking recently. The results, which come from the Otago Regional Council's own monitoring page, showed E. coli levels spiking above minimum acceptable standards about July 28, while there have also been breaches of compliance for suspended solids on at least three occasions in the past month. From August 18, instead of testing weekly and having weekly site visits, the ORC will shift to monthly testing and visits, although there will still be weekly water testing of the Kawarau River downstream of the treatment plant site.

Whanganui West Catchment Group to reveal results from three years of water testing
'On the other hand, E. coli bacteria continue to cause concern, and the group is refining its surveying to try to find better ways to reduce that persistent problem,' it said. 'The work is separate from Horizons' [Regional Council] monitoring, which gives rise to warnings in summer to bathers at Kai Iwi and Ototoka.' Earlier this year, swimming at Kai Iwi was off-limits for several days, after detection of high levels of enterococci bacteria. Whanganui Region Catchment Collective (WRCC) co-ordinator Natasha de Rose said volunteers undertook the sampling at 82 sites. The WRCC is the umbrella organisation for the West Whanganui group. 'We always need more buy-in, but there are certainly some farmers who are pulling their weight and doing a lot of stuff on their properties,' de Rose said. 'I think farmers got sick of the narrative that they were causing E. coli in swim spots, and that's been a big driver for them behind the scenes.' The Mowhanau Stream is one of five in the Whanganui West catchment. Photo / NZME Russell said the group was 'a very small cog in the big picture'. 'It all feeds into what New Zealand Inc is getting for produce overseas,' he said. 'More and more of our red meat customers, the likes of [United Kingdom supermarket] Sainsbury's, are starting to ask about the environment from which their meat is being supplied and whether it's being looked after.' He said, historically, there had been minimal water testing in the area. 'This report is forming the basis of what our next actions will be. 'It is a long-term thing we're looking at. We have to hold our position in terms of water quality, and try and improve it.' De Rose said funding for the group's work came from the Ministries for Primary Industries and Environment via the WRCC, with additional funding for sampling and reporting from Wai Connection. 'There are a few catchment groups up and running now, like Okoia and a little one in the back of Brunswick down to Papaiti. 'They are up country as well, through to Taumarunui and beyond. 'We are all trying to do the same things, but working together makes it a bit easier.' Russell said in the 1970s and 1980s, the focus in the Whanganui West area was to clear land and grow grass. 'The focus for this generation is actually looking after the environment, waterways and biodiversity. 'We'd like to see more farmers getting involved, and we'd like more members. The more the merrier.' The report will be presented at the Mowhanau Beach Community Hall on July 24 at 7pm. Mike Tweed is a multimedia journalist at the Whanganui Chronicle. Since starting in March 2020, he has dabbled in everything from sport to music. At present his focus is local government, primarily the Whanganui District Council.

Kāeo's decade-long boil-water notice raises health concerns
Valentine said the colour of the water had improved in recent years, but it was still no good for drinking. In July 2015, Northland's Medical Officer of Health issued a boil-water notice because of levels of E. coli bacteria found in the water. That notice had never been lifted. Kāeo Water supplies just under 30 customers – a mix of homes, businesses and public facilities such as the toilets and community hall – on State Highway 10, the town's main street. Rather than face the cost of constantly boiling water, the Valentines have rigged up a tank for catching rainwater and every day they use it to fill up bottles for drinking water. Valentine said she had organised public meetings and lobbied the council in the past, but little had changed. 'The water needs to be drinkable out of the tap, for the kids that go to the community hall, and the people coming through town. They don't know that it's not drinkable. The businesses in town, a lot of them have installed their own rainwater tanks because they just can't rely on the water.' Kāeo chef Anna Valentine says her children have never known what it's like to drink out of a tap. Photo / RNZ Until the year 2000 Kāeo's water supply was owned by the Far North District Council. The council sold it to Doubtless Bay Water, which quit in 2008, saying it was not economically viable. It was then taken on by Wai Care Environmental Consultants. Kāeo Water operator Bryce Aldridge said it was difficult keeping up with ever-changing drinking water standards, especially for a small scheme like Kāeo's. 'And the Government's not assisting with the upgrading that's needed to meet those standards, because of the size of plant that we are.' Aldridge said he had never put up the price of water, and only a small minority complained about the quality. 'It's actually only one client … I have spoken to the other clients, and this is their fear [if the system is upgraded]: the water price going up, and the battle of having to put fluoride in our water, so a boil water notice actually protects us there.' The Ministry of Health has recently ordered the Far North District Council to add fluoride to its Kerikeri and Kaitāia town water supplies, but a spokesperson told RNZ the ministry did not order fluoridation of privately-owned water supplies. Aldridge said the discolouration was caused by iron and manganese naturally present in the source water from the Waikara Stream. Removing iron and manganese completely was difficult and required multiple treatment stages. He said the next step for the water scheme would be to move the plant to a new location, and introduce UV treatment. He told RNZ he had secured a new location just last week, but that had yet to be confirmed. Kāeo's private water treatment plant, on School Gully Road, draws from the Waikara Stream. Photo / RNZ Aldridge said he welcomed media scrutiny because it had caught the attention of Taumata Arowai, the national water authority, and had bumped Kāeo's water supply up its priority list. Taumata Arowai head of operations Steve Taylor said even a small private drinking water supply such as Kāeo's had to meet the requirements of the Water Services Act 2021 and other rules. The authority had sent a letter outlining its expectations in March, but a meeting scheduled that month had been cancelled by the supplier. Expectations included boil-water notice communication with consumers, and providing a confirmed, funded plan for achieving compliance with legal requirements. Taylor said those expectations had not yet been met. The authority had set a new date of July 23 for meeting the supplier and inspecting the plant. Taylor said boil water notices were only meant to be a temporary solution, because over time people could forget and risked drinking contaminated water. The authority could take action if it believed a supplier was not responding adequately to concerns about unsafe drinking water or failed persistently to comply with legal requirements. That could include requiring the local authority, in this case the Far North District Council, to take over the supply. All Kāeo Water's customers are based on the Far North town's main street. Photo / RNZ Te Rūnanga o Whaingaroa pou arahi, or cultural manager, Raniera Kaio said the scheme had suffered from buck-passing between the council and the operator as to who was responsible. He believed the only way to fix it was by the council, the operator and iwi working together. 'My personal opinion, indeed my professional opinion, is that the operator lacks the resources to fix it. Lacks the resources to fix it alone. It has to be a collaborative solution.' Kaio said the water plant had been inundated in the 2007 floods and never fully recovered. The boil-water notice also had a financial effect on the rūnanga, which spent $300-$400 a month on bottled water for staff and manuhiri [visitors]. He said Kāeo's water woes were emblematic of the neglect suffered by many rural, Māori-majority towns. The effects went well beyond the cost and inconvenience of having to boil water or buy it by the bottle. 'It's about the dignity of Kāeo, the mana of Kāeo. And whānau in Kāeo have lived with daily anxiety around whether their water is safe to drink, that really affects not only your health, your hauora [wellbeing], but it sort of affects your own self-worth and your identity as being from Kāeo.' However, Kaio said he was buoyed by news that Taumata Arowai was about to meet the operator, and hopeful a solution could be found. Meanwhile, Anna Valentine just hoped one day soon her children would be able to drink water out of the tap. 'I mean, we live in New Zealand, but it feels like we're in a bit of a third world country up here in Kāeo, having to go out every day and fill our plastic bottles from a water container that we collect off the roof. It's just crazy, actually.' Kāeo's boil-water notice is not the longest-running one in the country. A 2024 Drinking Water Regulation Report stated 74 long-term 'consumer advisories' – which include boil-water notices – were in place at the end of last year, and 20 council supplies serving a total of 7000 people had advisories in place for three or more years. 'The persistence of long-term consumer advisories represents a significant regulatory and public health challenge,' the report stated.
