Rising Concerns The Invisible Threat in Water
Experts are ringing alarm bells over the need for more stringent controls on the levels of ‘forever chemicals’ in UK drinking water, highlighting potential grave health implications. These chemicals, known formally as PFAS (Per- and polyfluoroalkyl substances), are notorious for their persistence in the environment and the human body, hence the moniker ‘forever chemicals.’ High concentrations have been associated with alarming health issues, including cancer and fertility problems.
Current Measures Are They Enough?
Despite the government’s assurance of “exceptionally high” safety standards, the Royal Society of Chemistry (RSC) is pressing for regulations to be tightened, in keeping with measures adopted by other nations. These ‘forever chemicals’ are pervasive, found in everything from food packaging to cosmetics, owing to their water-resistant properties. They infiltrate water systems when products containing them, like non-stick cookware and certain clothing, deteriorate.
While UK water companies are mandated to monitor 47 different PFAS types, current guidelines set by the UK’s drinking water inspectorate only advise against using water for drinking if high-risk levels are detected. This, according to the RSC, still subjects the population to medium-risk levels and ignores the thousands of other PFAS types.
A Call for Change Aligning with Global Standards
The RSC recommends a tenfold reduction in acceptable PFAS levels and advocates for comprehensive testing of all PFAS. This proposal aims to align the UK with the US’s stricter regulations and the EU’s impending tougher restrictions. “The science has changed,” Stephanie Metzger, an RSC policy adviser, explained to the BBC, referencing evolving research indicating that health effects may occur at lower PFAS exposure levels than previously thought.
Technological Challenges and Environmental Impact
Traditional water treatment methods falter in eliminating PFAS, leading to alternative strategies like blending water from various sources to minimize concentration. Emerging technologies, such as high-pressure membranes, are also under exploration. However, concerns extend beyond human health, with scientists worrying about PFAS’s impact on aquatic wildlife. Despite water with high-risk PFAS levels not being utilized for drinking, the inconsistency in toxicity standards for humans and wildlife is a point of contention among experts.
Forward Momentum Next Steps in Chemical Regulation
In response to these concerns, the RSC urges the establishment of a national PFAS inventory and a dedicated chemistry regulator, especially since the UK’s departure from the EU left a regulatory gap. The government pledges continued work to evaluate PFAS levels, sources, and associated risks to shape future policies. Meanwhile, Water UK, representing the water industry, reiterates its commitment to delivering high-quality drinking water, complying with rigorous regulatory standards.
This developing situation underscores the crucial balance between industrial chemical use, environmental safety, and public health, pushing for a reevaluation of chemical management practices in the modern world.
