When Third Energy announced plans to frack one of its wells at Kirby Misperton, people in the North Yorkshire village decided to monitor the effects for themselves. They began by collecting data to establish a baseline against which impacts could be compared. In this guest post, Mike Potter, a member of the Kirby Misperton Monitoring Group, explains why, how they did it and what they found out.

Living near a planned fracking site prompted me to look into high volume high pressure hydraulic fracturing about six years ago. But when reasonable questions and suggestions were met with silence, half-truths and weasel words, I became highly suspicious.

A key failing in the early days of fracking in other countries was that baseline data was rarely collected.

How could harm, detrimental effects, or even benefits be recognised when there was no evidence of how things have changed? How can effective regulation be put in place without robust understanding of harmful effects? Fracking is a completely untested process in this country, apart from the Cuadrilla example at Preese Hall in 2011, so no evidence base exists for the UK.

I asked for baseline assessments of health, air and water quality before any fracking took place. I said there should be environmental impact studies using evidence from existing fracking operations. This should be followed by a sensible period of ongoing monitoring of any potential impacts if the industry were to expand commercially. I suggested that data collection and analysis should be strictly independent wherever possible and with an extremely robust provenance.

I received neither response nor reassurance.

After about nine months, I decided there was no justification to trust the word of either industry or government until I could see some commitment to my requests.

Eventually the government agreed to fund independent monitoring led by the British Geological Survey (BGS) in and around the Kirby Misperton site and at Preston New Road, where Cuadrilla was planning to frack. This work, carried out with four universities and Public Health England, was additional to monitoring required by regulators.

While this monitoring was welcome, it did not cover all the impacts that fracking may have on the local community. Noise and traffic levels were not included, and initially, air quality was measured only at the KM8 well-pad itself.

So a group of concerned residents came together and formed the Kirby Misperton Monitoring Group (KMMG) to address some of these issues.


We wanted to be sure that appropriate monitoring was in place and accurate baselines were recorded before any fracking-related disruption happened.

We also wanted to establish if there were any gaps in the monitoring by the British Geological Survey, Third Energy and the regulators.

Making our own baseline measurements would give us a solid understanding of the measurement process and the conditions in the area before fracking happened. This would make us better placed to talk about the issues and to hold the operator and/or the regulator to account if we needed to.

Having our own data would mean we would be prepared to challenge any future planning applications if we wanted to.


In deciding what we would monitor, the most important considerations to us were cost, trustworthiness and reliability of results.

Equipment and methods would have to conform to accepted and proven protocols for results to carry as much weight as possible. So, for example, chemical analysis of water samples had to be conducted by an accredited laboratory and traffic surveys were conducted according to industry guidelines.

This wasn’t about being pro or anti fracking.

It was about collecting unbiased data that would allow us to recognise harmful effects on local communities or ecosystems if or when they occurred.

Some people will ask ‘why would we trust your results?’ The use of industry standard protocols means we can robustly defend our findings. We can also compare them to those of BGS and Third Energy and they should closely match. If not, there are serious questions to be answered of ‘whose are wrong, and why?’.

The group initially identified 13 areas where monitoring would be useful. But we prioritised four areas: noise, air, water and traffic.

We believed this was where the immediate possible impact on the community was likely to be greatest and we could make good quality measurements.

Traffic: We carried out six weekly 12-hour surveys and used static cameras at two locations.

Air quality: We had six locations recording nitrogen dioxide and benzene levels.

Water quality: We had access to five boreholes and wells around Kirby Misperton

Noise: We monitored 24/7 about 800m from the site and within the village

Other: We also monitored complaints to police, arrests and incidents.


We appointed two people to lead on each priority area. We developed project plans to track progress, cost, equipment and standards. We bought traffic cameras, air sampling kits, water borehole tests, noise monitoring instrument and a weather station.

Funding for KMMG has come from a combination of our own pockets, other local people who agree with our aims and objectives, and donations from a number of businesses with strong green credentials.

Unsurprisingly, we would welcome further unconditional donations. As you would expect, the most valuable contribution has been the considerable time, commitment and knowledge of our members.

KMMG has brought together people with a diverse range of expertise, and we have sought further advice and learnt a great deal along the way.

For efficiency, small teams work on each of aspect of the monitoring according to their relevant skills and interests, and the wider group meets regularly to share and discuss progress.  For example, traffic surveys require plenty of volunteers (we had a team of 30) with the concentration and perseverance to accurately count vehicles in miserable weather for an hour or two, while other aspects of our monitoring have required fewer people, but more specialist knowledge.


We identified key traffic locations and recorded vehicle types and numbers, as well as traffic incidents.

Air quality

Measuring potential air pollutants, including diesel exhaust, dust, hydrocarbon compounds and methane, requires specialised equipment, and expertise.

We focussed on methods that were relatively low cost, that could give us accurate, quality-controlled results to industry standards and that we could conduct and interpret. Our data was complementary to the BGS air quality monitoring, which was just at the site, while our measurements were around the village.

We used diffusion tubes, which were industry standard and analysed at an accredited lab.

Water quality

We identified where Third Energy’s consultants planned to monitor ground and surface water and we looked for gaps in this monitoring.

We used a suite of tests to measure dissolved gases, chemicals and typical fracking-related compounds. This was considerably broader than Third Energy’s monitoring. The test company supplied transport and bottles for testing, guidance and information sheets to ensure we collected clean specimens.


We acquired industry-standard equipment, including a monitor, monitor calibration device and a weather station.

We sited the noise monitor and weather station 810m from the well site in a resident’s garden. It was 10m away from Third Energy’s equipment. The weather data is essential to interpret noise measurements.


Traffic: Traffic management plan breached nearly every day

KMMG traffic 3

We now have clear evidence that Kirby Misperton Village residents were severely disrupted by the traffic associated with the preparations to frack the well site at KM8. There is robust data we can use to address any future planning applications.

There was a 30% increase in traffic movements at the start of site preparation at KM8. 25% of the increase was light goods vehicles and vans. Police vehicles accounted for 10-15% of daily movements. These comprised 100 movements through the village each day that had not been accounted for in the Traffic Management Plan (TMP), approved by North Yorkshire County Council.

We discovered that the TMP was breached virtually every day and no-one accepted responsibility for the breaches. The county council blamed the Police. The police blamed Third Energy. Ryedale District Council appeared to do nothing.

We know that heavy goods vehicles (HGVs) delivering to the KM8 site were too big to navigate roads in the villages around Kirby Misperton. We now know what traffic comes through Kirby Misperton every day. We also know what the limits are on the amount and type of traffic the village can accommodate in future.

Air quality: increase in nitrogen dioxide with site preparation

KMMG air

We discovered that nitrogen dioxide levels were highest at the well-site, peaking in November 2017. The lowest levels were upwind of the KM8 site. In the village, the highest levels were on the main road through the village.

As well as our own monitoring, we followed the more detailed BGS air quality data (made available online) on particulates and a range of gases. This helped us to understand the impacts of site activities on air quality.

The online BGS data, and recently-released Environment Agency data, also showed large increases in nitrogen oxide levels once activity at the KM8 site began.

Water quality: No evidence of contamination

We did not find evidence suggesting any oil and gas contamination prior to fracking taking place.

We found that many farms were reluctant to allow us to test their boreholes. We also discovered that there are considerably more boreholes than we originally thought. Potential groundwater contamination from fracking is a greater threat to farmers than they may realise.

Noise: Realistic baseline

We can now give the planning authorities a realistic baseline for local noise levels. We also have actual data on the noise levels, duration and quality that communities may experience at different stages of fracking development.

This information could allow people to identify breaches of planning conditions and alert the authorities.

Noise monitoring equipment is very technical and sensitive. Training is essential for both site location, data downloads, maintenance and data analysis.

What we also learned?

We have a better understanding of what needs to be monitored, how this can be done and how to identify when breaches occur.

We have improved our knowledge of monitoring procedures, both generally and at the KM8 site specifically. This has helped us to assess what we have been told by the regulators and Third Energy, and to interpret the data from BGS.

We highlighted that onCline data streamed from the BGS seismic equipment was not scaled correctly, meaning seismic events were not being shown. Additionally, one of the six units was not streaming in real time due to the lack of 3G connection. We raised these issues with BGS, which corrected them, ensuring that seismic data for KM8 was publicly available

We successfully recorded the data we wanted to and we now know where the gaps are. We won’t be blindsided in the future on monitoring issues.

We could have better communicated the results to the village on what we achieved. We need to improve our ability to consolidate and record incidents of all types.

We would like to carry out baseline methane monitoring of the area before drilling and fracking. This will conclusively show any fugitive emissions if or when fracking takes places but it is a very expensive procedure.

We learned that having technically-savvy people on the team was essential. We needed people who could analyse data, install and set up equipment and communicate with the group. We are very grateful for the time and effort given up by the circa 38 people who made up the group.

And finally, we also learned that we needed to plan for separate, secure and consolidated data storage.

Key lesson

The efforts of KMMG members demonstrated how seriously some in the local community are concerned by the prospect of fracking in Ryedale and far beyond.

When significant numbers of rational, intelligent local people recognise the need to commit so much of their time, effort and tenacity over a long and indefinite period of time to such an end, you really have to ask the question why?

  1. This is so encouraging and so needed! Well done to Mike Potter and the team. The fact that it is necessary for members of the public to do this key work is an appalling reflection on (the lack of) government policy and action, for it is they who should be setting this up with BGS and others. The KMMG can be very proud of what they are doing…..would that others could do the same in order to test replication of results and data.

  2. An excellent report and very well done to the KMMG, truly inspiring. It will be interesting to see the results, when and if they frack at that site. And I wonder what the monitoring results will be for the construction of a well pad, drilling a new borehole and fracking because this is what communities face and it is an even more disruptive process.

  3. Third Energy has a controversial fracking site at Kirby Misperton in North Yorkshire, while the council’s fund has £81 million invested in other companies fracking across the world

    North Yorkshire Council doesn’t seem to have a problem with fracking…

    • Not quite true Kisheny. Staunchly Tory NYCC has a problem with the planning regulation of fracking being removed from it’s control and has communicated that concern to the govt.

  4. This is evidence of the intelligent, dedicated and determined work that a community can muster when faced with a threat from an industry that quite obviously is more concerned with making profit regardless of the consequences. I hope the Government will take note and realise that trying to impose an unwanted and unnecessary industry upon the public will not work.
    Our Government need to look around the world and take a lead by working much more speedily towards renewable energy rather than promoting Fracking for very dubious reasons.
    Dave Adam.

  5. Fantastic works. While these findings may or may not be accepted as valid by those involved it show that there are people out with valid and real concerns issues that they undertake significant effort to understand the problems.
    Well done to you sir and those involved.

  6. This work is truly inspirational and an excellent lead for other groups around the country. Gold standard regulations mean diddly squat unless the local communities can hold them to account with industry standard arguments.

  7. A fantastic report highlighting exactly why we can’t trust the Gas companies or the planning conditions placed upon them. ‘Traffic management plan breached every day’…..says it all.

  8. Very good. I expect the same due diligence and monitoring will take place for housing developments in the area (and any other construction activities) as nitrogen oxide and benzene levels will rise in line with increased traffic. And monitoring of TMPs and wheel washing etc….. Flamingo Land parking lot…..

    Potential ground water pollution is a greater threat from farmers.

  9. Thanks for providing such a thorough update. It’s clear the gold standard regulations mean nothing to the drilling companies. Fines if handed out would be paid but it’s the lives of the residents and animals which are being put at risk. This should be used as a template for any other sites. Thanks for all your efforts.

  10. Good to see some “citizen science” here. Well done! Please ensure you keep records of the meteorological (including barometric pressure) & ground conditions when you take measurements of air & groundwater. These can have significant effects in causing peaks. Also note farming activities as these can raise NOx & methane too.
