A second round of water sampling on the River Nidd has confirmed high levels of the faecal bacteria E.coli.
Volunteers tested for E.coli levels along the length of the Nidd as part of a clean-up campaign amid concerns about the state of the river and reports of bathers at Knaresborough Lido suffering sickness and diarrhoea.
The first round of sampling took place in August and the laboratory results of the second round, which took place a fortnight ago, were released last week.
David Clayden, chairman of Nidd Action Group, which coordinated the sampling, said the latest results confirmed the previous findings, which showed concentrations of E. coli bacteria were above acceptable limits.
He added the locations identified as E.coli hotspots in August once again produced the most concerning results.
Tributaries in the middle and lower Nidd catchment, including Ripley Beck, Oak Beck and Crimple Beck, had the highest concentrations of E.coli, with Bilton Beck the worst.

Sampling at Oak Beck in August.
In general, concentrations of E. coli were much lower in the upper catchment of the river from Pateley Bridge to Birstwith, than in the middle and lower catchments.
Knaresborough sampling locations revealed concentrations above the levels deemed sufficient for inland bathing water.
The Nidd Action Group committee met on Friday to talk about next steps, which will include organising a second public meeting to discuss progress and plans for 2024.
Mr Clayden said the meeting will be held in Knaresborough in early December and would follow a similar format to the one staged in March this year.
Meanwhile, Andrew Jones, the Conservative MP for Harrogate and Knaresborough, is expected to submit a bid to the government in the next few days to designate bathing water status on the Nidd.
If accepted, agencies will be obliged to undertake measures to clean the Nidd, as has happened on the River Wharfe in Ilkley.

A Harrogate conservationist has called for signs to be put up urging children and dogs to avoid entering Oak Beck.
Keith Wilkinson described the situation as “desperate” after a series of incidents over the last fortnight have seen the beck turn brown.
The Environment Agency said last week it was “investigating the possible source of the pollution” after receiving “a number of reports of discoloured water”.
But after a brief recovery, the beck was heavily discoloured again today.

Oak Beck in Jennyfields this morning
Mr Wilkinson, who is honorary secretary of Bilton Conservation Group and chairman of the Nidd Gorge Advisory Partnership, said:
“The Oak Beck situation is desperate with daily pollution events for two weeks now — sand and silt from construction work, solids escaping from the open storm drain near The Hydro and a constant stream of what looks like detergent foam from high up near Birk Crag.
“It is totally unacceptable. Signs are needed urgently to warn children and dogs to keep out of the water.”
An Environment Agency spokesperson said:
“At the moment as investigations are currently ongoing so we are unable to comment further in order not to prejudice our enquiries.”

The Environment Agency is investigating possible pollution of Oak Beck in Harrogate.
Residents complained to the government organisation about water looking like “milky coffee” over the past couple of days.
The Stray Ferret contacted the Environment Agency to ask whether it was investigating any incident in relation to discoloured water in the beck.
A spokesperson said an officer was on site yesterday to take samples of the water.
They added:
“Over the past few days, we have received a number of reports of discoloured water in Oak Beck, Harrogate.
“An officer attended site yesterday to take samples, and we are currently investigating the possible source of the pollution.”
Hundreds of fish are believed to have died in an Oak Beck pollution incident in September last year when the water turned brown.
Dead fish could be seen in the watercourse at Oak Beck retail park.
The incident prompted leading Harrogate conservationist, Keith Wilkinson, to call on Yorkshire Water and the Environment Agency to step-up efforts to work together to prevent pollutions in the beck, which he said occur too frequently.
Oak Beck, which flows across northern Harrogate, empties into the River Nidd at Bilton.

Yorkshire Water pays £235,000 for illegal Harrogate sewage discharge
Yorkshire Water has agreed to pay £235,000 to charity for illegally pumping sewage into Hookstone Beck in Harrogate.
The Environment Agency said today the company breached its environmental permit by discharging sewage from its Stray Road combined sewer overflow into the beck, which flows between Hookstone Road and Crimple Beck.
Following an Environment Agency investigation, Yorkshire Water volunteered to make amends for its offence.
It agreed to pay the sum to Yorkshire Wildlife Trust, which will use the donation on environmental improvements in North Yorkshire including native crayfish conservation and reed bed management at Ripon City Wetlands.
The Environment Agency said the Stray Road combined sewer overflow, near Tewit Well, has an environmental permit which allows a discharge into the beck when the storm sewage facility is fully utilised due to rainfall or snow melt.
On 27 August 2015, it discharged illegally during dry weather and sewage fungus was evident on the bed of Hookstone Beck.
Yorkshire Water has now upgraded its telemetry to allow continuous monitoring of the storm overflow.

The company agreed to an enforcement undertaking, which is a voluntary offer made by companies and individuals to make amends for their offending, and usually includes a donation to a wildlife charity to carry out environmental
Claire Barrow, Environment Agency area environment manager, said:
“Sewage pollution can be devastating to human health, local biodiversity and out environment. Storm overflows must only be used under strict permitted conditions that control their environmental impact.
“We are holding the water industry to account like never before and while we will always take forward prosecutions in the most serious cases, enforcement undertakings are an effective enforcement tool to allow companies to put things right and contribute to environmental improvements.
“They allow polluters to correct and restore the harm caused to the environment and prevent repeat incidents by improving their procedures, helping ensure future compliance with environmental requirements.
A Yorkshire Water spokesperson said it had made “significant improvements in our operations since this incident in 2015″, adding:
“When things go wrong, we understand we have a responsibility to make it right.”
A Yorkshire Wildlife Trust statement said:
Volunteers learn to test for E coli in River Nidd“Nature is in crisis and we firmly believe polluters causing damage to the environment must make amends, including through clean-up operations and fines.”
Dozens of volunteers will be heading to the River Nidd today as part of a project to find out how much E coli bacteria is in the water.
Around 40 people will be gathering near Conyngham Hall in Knaresborough to learn how to take valid samples from the Nidd – from the bankside and from bridges over the river.
The volunteers will then turn out again in force on August 3 to put their training into action and take samples from all stretches of the river from Scar House Reservoir at the top end of Nidderdale right down to Moor Monkton, where the Nidd joins the Ouse in the Vale of York.
They will repeat the process at the end of September, in an initiative that forms the centrepiece of an iNidd project organised by the Nidd Action Group (NAG).
All the water samples will be sent for laboratory testing to find out how polluted they are, both with faecal and chemical inflows.
David Clayden, chairman of NAG, said:
“We want to find the truth. I don’t think people know enough about the river. This whole project is about understanding the chemical and biological profile of the river, including the tributaries, specifically Oak Beck, Crimple Beck and possibly also Ripley Beck.
“It will give us data from all up and down the river, all taken on the same day, under the same conditions, which has never been done here before. A lot of preparatory work has gone into this and it’s all coming together very well. It’s very exciting.”
The samples will enable NAG to establish the concentration of faecal coliforms – or E coli – associated with human and pet health, nutrient chemicals such as phosphates and nitrates, and concentrations of heavy metals – all associated with the ecological balance of the river and the richness and variety of invertebrate and plant life.
Mr Clayden said:
“If a water sample is good, that’s great. But if it’s bad, we want to know what’s upstream of it – a sewage outlet, a farm, or a caravan park perhaps? We need to gauge the relative importance of different pollution sources.”

NAG hopes to be able to publish the results of the lab tests in the autumn, around the same time that Andrew Jones MP is due to submit the case for River Nidd bathing water status for consideration by Defra (the Department for Environment, Food & Rural Affairs).
NAG is also working with the Environment Agency on an “outfall safari”, which involves walking along the river bank and spotting unmapped pipes and other sources of pollution.
Mr Clayden said:
“You’d think they would know where they all are, but they don’t. A lot of these pipes have just been wrongly connected, either intentionally or by accident, and they may come from any private property along the river bank.
“So we need volunteers to spot them and report on how much pollution they’re causing. It involves investigative, observational work, and some training may be given by the Environment Agency.”
NAG was formed in September 2022 after concerns about the quality of the water in the Nidd were raised by anglers and others. It now has 100 volunteers.
Mr Clayden said:
“It’s a nice community, and one thing they all have in common is that they all love the river.”
Anyone wanting to join them and get involved with research on the River Nidd should use the Get Involved page on the NAG website.
Bed race entrants urged to ‘keep your head above water’ when crossing polluted NiddGreat Knaresborough Bed Race competitors crossing the polluted River Nidd this weekend have been urged by organisers to keep their heads above the water.
Last week a young child was reported to have been taken to hospital with an E. coli infection after playing in the river at Knaresborough.
It came after a report by Professor Peter Hammond, a retired professor of computational biology, last month revealed the equivalent of 317 Olympic pools of raw sewage were discharged into the river at four sewage treatment works in 2020.
Nidd Action Group and Harrogate and Knaresborough MP Andrew Jones are campaigning for a stretch of the Nidd at Knaresborough Lido to be granted bathing water status, to ensure the river is cleaned up.
Saturday’s bed race will see hundreds of competitors crossing the river as part of the course.
Bed Race chairman Martin Brock, of Knaresborough Lions, said:
“It goes without saying that we wish the youngster a speedy recovery from their infection. We know for our teams and the crowds that the river crossing is an integral part of bed race and one that they look forward to every year. The teams recognise when signing up for the event that they are participating at their own risk.
“We will flag at the team briefing about the Nidd, although it is local knowledge that the water isn’t perfect, and that when crossing, you keep your head above water.”
Safety measures
Last year, the Nidd saw 870 sewage dump incidents, according to Environment Agency figures, and recent water testing by researchers from the University of Leeds has shown the harmful bacteria E. coli is at unusually high levels.
E. coli is a bacterial infection that can cause severe stomach pain, bloody diarrhoea and even kidney failure. It is found in the gut and faeces of many animals, particularly cattle. Its presence at such high levels in the River Nidd is thought to be caused by either sewage dumps or by run-off from livestock farmland – or both.
Mr Brock added:
“Ultimately, no one is forced to go through the river and we do implement safety measures if teams choose to cross including limiting the number of beds in the river and having divers from the Upper Wharfdale Fell Rescue Association in the Nidd.
“The final decision to cross the river is taken on the morning of the race and if advice is given that it is unsafe, we would cancel the crossing. However, as things stand, with the recent spate of fine weather and a low river level, we are planning for the traditional river crossing on Saturday 10th.”

Harrogate and District Green Party said today the bed race was “an incredible event… being put at risk by Yorkshire Water’s cavalier approach to their sewage problem”.
It accused the government, supported by local MP Mr Jones of “putting profits before people”.
Mr Jones replied by saying recent data showed E. coli levels had drastically dropped and urged the Greens to join the Nidd clean-up campaign. He added:
“Politicians laying blame at one another’s door for a situation that has existed ever since the Victorians built our sewerage system is not constructive.”
The annual bed race was first held in 1966, and sees 90 teams of seven complete a 2.4-mile course around the town. This year’s theme for the pre-race fancy-dress parade is “That’s Entertainment”.

Yorkshire Water chief executive apologises for sewage failures
The chief executive of Yorkshire Water has apologised today for its record on sewage and said she will refuse any bonus this year.
Nicola Shaw admitted the company has not done enough to tackle storm overflows, which release raw sewage into rivers at times of high rainfall.
Yorkshire Water has been widely criticised for its record on storm overflows and was fined £233,000 in January for discharging 20 million litres of raw sewage into Tong Beck at Bradford.
Ms Shaw joined the company in May last year and has yet to receive an annual bonus. Her predecessor Liz Barber’s last bonus was £679,000 in the 2021/22 financial year.
In a letter to customers, Ms Shaw said:
“There has been a huge amount of criticism of, and anger at, the water industry over recent months.
“I get why people are angry – seeing sewage in our rivers and seas isn’t right. We should have a system that befits the 21st century. So, on behalf of Yorkshire Water, I am sorry.
“We should have acted more quickly to change the situation. That’s why I have decided to refuse any bonus this year as I want us to make progress.”

- Yorkshire Water discharged sewage into River Nidd 870 times in 2022
Ms Shaw pledged the company would “up its game” by improving the 190 storm overflows “that we know are operating much more than they should” and by “delivering our largest environmental investment ever”.
Yorkshire Water will spend £180m on storm overflow improvements in the next two years, which it said would help to reduce discharges by at least 20%.
The £180m investment will be spent on:
- Increasing storage within Yorkshire Water’s wastewater treatment works
- Preventing surface water entering the sewer system
- Reducing infiltration into sewers
- Small changes to the operation of treatment works.
There is no shortage of concern about the state of the River Nidd, as a busy public meeting in Knaresborough demonstrated this week.
About 70 people turned up at Gracious Street Methodist Church on Tuesday to listen to academics, anglers, environmentalists and politicians and to find out how they could get involved in the attempt to achieve bathing water status.
Just two rivers in England — the Wharfe in Ilkley and Wolvercote Mill Stream in Oxfordshire — currently have bathing water status, which obliges the Environment Agency to put plans in place to monitor and protect the water.
Nidd Action Group has been set up to coordinate the initiative.
James McKay, a Knaresborough resident and manager of the Water-Wiser centre at the University of Leeds, told the Stray Ferret at last week’s meeting Nidd sampling had begun and the campaign had the funds and expertise to achieve its goal.
Mr McKay said the group needed to demonstrate enough people used the river recreationally for the campaign to be successful.

James McKay speaking at the meeting
He said the process of achieving bathing water status wasn’t easy but “it’s the only thing we can do to make a real difference to water companies”.
Mr McKay said water companies were obliged in 2023 to update their water resource management plans for the next five years and the goal was to achieve bathing water status by then. He added:
“If we succeed it won’t have an immediate effect. The first thing that would happen is Yorkshire Water would have to do its own sampling. But over the next couple of years it could start to make a big difference.”
Untreated sewage
Although Knaresborough Lido is the focus of the campaign, if bathing water status is achieved it would bring improvements to the upper reaches of the 56-mile Nidd, including around Pateley Bridge, which flow into the Lido.

Alan Paterson addressing the meeting
Alan Paterson, of Nidd Action Group, told the meeting the three main causes of river pollution were sewage, agricultural contaminants and urban run-off. He said the first two were the main issues affecting the Nidd.
In 2021, Yorkshire Water pumped untreated sewage from 81 locations into the River Nidd 2,552 times – for 18,346 hours, or 764 days.
Mr Paterson said Yorkshire Water’s plans to clean-up the Nidd were “good but would take far too long” and bathing water status would oblige it to act sooner.
Andrew Jones, the Conservative MP for Harrogate and Knaresborough, has led on the campaign to achieve bathing water status and has been looking for volunteers to undertake surveys before he can submit an application. He has also raised the matter in Parliament.
Mr Jones wasn’t at the meeting but Stephen Culpin, a member of his office, was. Mr Culpin said afterwards the intention was to finalise and submit the application by the end of October.

Mr Jones (left) with Frank Maguire, the owner of Knareborough Lido.
The government’s record on sewage discharge has been fiercely debated. Mr Paterson said declining funding to key regulators such as the Environment Agency suggested ministers did not take the issue that seriously but he added that although the action group was “entirely apolitical”, Mr Jones deserved praise for his efforts.
“If he gets some brownie points then fair play to him because we need that bathing water status to improve the quality of water Yorkshire Water is discharging. I’d be deliriously happy if my MP, Julian Smith (the Conservative for Skipton and Ripon) got involved but he hasn’t.”
Mr Paterson added “rivers should be safe and clean to play and bathe in — it’s a right, not a privilege” and people attending the meeting were encouraged to volunteer by undertaking roles such as counting river users.
Wild swimming
Numerous groups attended the meeting but some river users, such as wild swimmers and kayakers, weren’t and some felt the campaign still needed joining-up more.
But the turnout and enthusiasm generated widespread optimism that people might soon be able to swim in the Nidd without a high risk of falling ill, as happened last summer.

Tuesday’s meeting at Gracious Street Methodist Church
Shan Oakes, a Knaresborough town councillor and member of Harrogate and District Green Party said:
“It was a hugely successful event and I feel confident that more like it will follow, bringing the community together to try to stop the pollution and bring back life to our lovely river.”
Yorkshire Water ‘keen to work in partnership’
Two days after the meeting, councillors on North Yorkshire County Council’s Harrogate and Knaresborough area constituency committee questioned a representative of Yorkshire Water as the issue of bathing water status was aired again.
Monika Slater, the Liberal Democrat councillor for Bilton Grange and New Park, told the meeting Leeds University researchers were now taking Nidd samples monthly and this would increase to fortnightly in May.
But she added the samples had so far discovered the harmful bacteria E. coli was at “concerningly high” levels.
Bilton Conservation Society is also sampling at Oak Beck, which empties in the Nidd at Bilton.
Sarah Robinson, from the corporate affairs team at Yorkshire Water, told the meeting:
“There are lots of influences on bathing water quality. It isn’t just about our assets — in some ways that would be easier because we could control that. “
The big issue for the Nidd, Ms Robinson added, was going to be agriculture, such as chemical run-off caused by farmers’ sprays. Dogs running in water also had “a massive impact”, she added. But she said the company was “very keen to work in partnership” to address problems.
The next six months will determine whether the good intentions, and the disparate interests, can be harnessed to achieve real change for the Nidd.
Developer apologises for debris in River Crimple at SpofforthA housing developer has apologised after debris from its site near Harrogate entered a nearby waterway.
Polystyrene and plastic from the 72-home Yorkshire Housing site at Spofforth was floating in the River Crimple in the village over the weekend.
Yorkshire Housing was granted permission to build the homes at Massey Fold in October 2021 after a long-running campaign by some villagers against the development.

The organisation, which owns and manages about 20,000 homes, said in a statement:
“On Friday, some insulation blew open in the high winds and broke up. The contractor notified the Environment Agency straight away to let them know what had happened.
“Because of the stormy weather over the weekend it wasn’t safe to retrieve and clear-up the debris until this morning. We’re working quickly to do this.
“Windy weather isn’t an excuse and this shouldn’t have happened. We’ve discussed this with the contractor who will ensure any loose materials are secure to prevent this happening again.”
Signs on site say the development, known as Bridgewell, will consist of two, three and four-bedroom homes built in partnership with construction company the Jack Lunn Group and the non-departmental housing agency Homes England.
Villager Mark Lee raised concerns about the incident on social media.

Conservationist Keith Wilkinson, who is chairman of Nidd Gorge Advisory Partnership and honorary secretary of Bilton Conservation Group, said the incident reinforced the need to look holistically at problems associated with Harrogate’s three rivers — the Nidd, Crimple and Oak Beck.
Mr Wilkinson said contamination from the Nidd tributaries inevitably impacted on the Nidd itself and therefore it would be better to adopt a more strategic view to managing water quality.

Stray Views: Concerns about housing scheme for Harrogate’s Knox Lane
Stray Views is a weekly column giving you the chance to have your say on issues affecting the Harrogate district. It is an opinion column and does not reflect the views of the Stray Ferret. Send your views to letters@thestrayferret.co.uk.
The report compiled by the case officer for Harrogate Borough Council about the proposed Knox Lane housing development ignores many facts.
It appears the application submitted in April 2020 is a Stonewater Housing Association/Jomast joint venture.
In the application for 73 homes, only 10 were open market. Fifty homes, including 10 open market ,were proposed on the allocated site, 80% affordable, the remaining 23 affordable homes were on adjacent unallocated land. The number of affordable (86.3%) is more than double Harrogate Borough Council’s HS2 Policy, despite pre-application discussions having taken place with council officers in September 2019. The following statements were included in supporting documentation with the application:
It is important to note that it was the applicant’s aspiration to provide a full affordable housing scheme on the site. However, an element of market dwellings has been introduced at the request of the council based on their reasoning that it would provide a more balanced scheme.
Due to the uncertainty in respect to the length of any lockdown and the fact that the scheme has already been consulted upon and the site is now an allocation, it is considered appropriate to submit the application rather than delay until some form of meaningful consultant can be carried out at some undetermined point in the future. There is a clear and pressing need for the delivery of housing of all forms within Harrogate.
Despite the application not being compliant with Harrogate Borough Council Local Plan policies it remained on the planning portal with consultees being contacted.
The revised application submitted in December 2021 excluded the 23 affordable homes on the unallocated land but included 30 (56.6%) in the new plan, still in excess of Harrogate Borough Council affordable homes policy and contrary to NPPF 47.
Consultations with residents were held in February and March 2018 when the land agent advised a proposal for 100% affordable homes on behalf of Wakefield and District Housing Association. It is now almost five years since these consultations were held yet no further consultations have been.
The link to Knox Country Park was requested by the case officer. He apparently has not considered the impact this will have on the newly planted habitat for wildlife. The extract from the ecological report submitted on behalf of the developer suggests the increase in footfall would.
Knox Lane comprised a single-lane road and associated footpath. It was lined on both sides by tree lines (including that one the western site boundary) and grass verges, with managed agricultural land beyond to the west. The tree lines may offer some nesting habitat for birds and foraging and commuting habitat for bats, but Knox Lane itself offers negligible suitable habitat for wildlife, comprising impermeable, artificial surfaces that are disturbed by human activity on a regular basis. As such, this area was assessed to be of low ecological value.
