Renowned adventurer Bear Grylls has sparked controversy with his recent comments regarding the quality of British tap water. The veteran explorer, known for his extreme feats and survival skills, claimed that the long-term health effects of poor-quality tap water can be "horrendous." During an appearance this week, Grylls acknowledged that while UK tap water is relatively better than that in many parts of the world, he still deemed it “terrible” due to the chemicals used during the water treatment process.
Grylls specifically highlighted the use of chlorine, stating, "It’s universally acknowledged chlorine is going to kill bacteria and parasites, but it’s not going to be good for your health.” His remarks resonate strongly given his adventurous background, which has included some of the most daring survival tactics, such as drinking his own urine. However, the adventurer’s critique has drawn scrutiny, as he is linked to a British company that markets water filters priced at £129.
Concerns about the safety of tap water in the UK have been increasingly prevalent, especially amid rising domestic bills, uneven water services, and high executive salaries within the water industry. A recent analysis uncovered the contamination of raw drinking sources across England with perfluoroalkyl and polyfluoroalkyl substances (PFAs), commonly referred to as ‘forever chemicals’. These toxic substances, including around 10,000 variants, have been associated with serious health risks such as various cancers, reproductive issues, and neurological conditions.
These findings highlight a significant concern as a research group from the University of Birmingham found that ten target PFAs were present in 99 per cent of water samples from the UK and 14 other countries. Professor Luisa Orsini from the university described PFAs as "silent killers," warning that even low doses could have adverse health effects over time. Despite the existence of ongoing legislative efforts to combat PFA pollution, experts like Professor Ian Cousins from Stockholm University have expressed alarm that the UK’s delayed response has resulted in unnecessary and long-term exposure for many residents.
The UK water industry has also faced considerable scrutiny in the past year due to incidents that have sparked public health alarms. In late 2022, a contaminated reservoir near Brixham in Devon led to over 50 illnesses after a damaged air valve allowed the parasite Cryptosporidium to infiltrate the water supply. Additionally, thousands of homes were affected after a petrol leak from an Asda filling station prompted Thames Water to issue a precautionary warning against using tap water for consumption. There have also been significant concerns about the presence of microplastics in the nation’s water supply.
In defence of the tap water quality, industry representatives from Water UK contend that nearly 16 billion litres of water are treated each day, asserting that it is among the highest quality worldwide, with 99.95 per cent of tests passed. Their position is supported by both the Drinking Water Inspectorate and academic experts, who maintain that the UK consistently ranks highly in international water quality assessments and that additives like chlorine are in safe quantities. Professor Peter Jarvis from Cranfield University stressed, "We do not want people to think that tap water is unsafe to drink... the benefits of adding chlorine to tap water significantly outweigh any of the often unproven negatives."
While concerns regarding tap water safety continue to generate debate, it remains clear that the issue is multifaceted, incorporating scientific, regulatory, and public perception dimensions. Grylls’ alarming claims highlight a growing unease within the public sphere, as authorities strive to assure citizens that their tap water remains safe for consumption.
