Managing water key for shale sites

Effective management of water at shale gas exploration sites is now the main concern of water companies rather than its availability, following engagement between the two industries.
A memorandum of understanding was signed by Water UK and the UK Onshore Operators Group (UKOOG) last November to ensure cooperation because extracting shale resources requires large amounts of water for drilling and hydraulic fracturing (known as fracking).
Since then a task group from both industries has been meeting regularly to discuss issues around fracking and water, a spokesman for Water UK said.
As a result, the providers believe that the main challenge will be ensuring surface water is not polluted when it returns from underground fracking operations. “We feel that we understand the risks a lot better now,” he said. “We feel the main area of risk is making sure they are no spills on site.”
Last month, the World Resources Institute published a report warning that companies developing shale resources are likely to face serious challenges in accessing freshwater in many parts of the world.
It highlighted water stress in areas of the UK where shale gas resources have been identified, such as the Bowland area in Lancashire and the Wessex-Weald area in the South East.
Companies developing shale resources in the UK could face regulatory and reputational risks if they do not actively engage with local stakeholders on water security, the institute warned.
Competition with other industrial water users and residents could cause costs to rise, it warned.
Globally, the institute found that 38% of shale resources are in areas that are either arid or under high extreme levels of water stress; 19% are in areas of high or extreme seasonal variability; and 15% are in locations exposed to high or extreme drought, the report states.
Demand for fossil fuels will peak by 2025 if all national net-zero pledges are implemented in full and on time, the International Energy Agency (IEA) has forecast.
The Green Homes Grant is set to deliver only a fraction of the jobs and improvements intended, leading to calls for more involvement from local authorities in future schemes.
COVID-19 recovery packages have largely focused on protecting, rather than transforming, existing industries, and have been a “lost opportunity” for speeding up the global energy transition.
Half of the world's 40 largest listed oil and gas companies will have to slash their production by at least 50% by the 2030s to align with the goals of the Paris Agreement, new analysis has found.
None of England’s water and sewerage companies achieved all environmental expectations for the period 2015 to 2020, the Environment Agency has revealed. These targets included the reduction of total pollution incidents by at least one-third compared with 2012, and for incident self-reporting to be at least 75%.
The UK’s pipeline for renewable energy projects could mitigate 90% of job losses caused by COVID-19 and help deliver the government’s ‘levelling up’ agenda. That is according to a recent report from consultancy EY-Parthenon, which outlines how the UK’s £108bn “visible pipeline” of investible renewable energy projects could create 625,000 jobs.
Billions of people worldwide have been unable to access safe drinking water and sanitation in their homes during the COVID-19 pandemic, according to a progress report from the World Health Organisation focusing on the UN’s sixth Sustainable Development Goal (SDG 6) – to “ensure availability and sustainable management of water and sanitation for all by 2030”.
