A recent independent investigation by Bluewater, a leading sustainable water purification and beverage solutions pioneer, has uncovered significant contamination of London’s tap water by health-threatening ‘forever’ chemicals, specifically PFOA and PFOS. These findings raise serious health concerns and highlight the urgent need for better regulatory measures in the UK.
Understanding PFAS ‘Forever Chemicals’
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that include PFOA and PFOS. These chemicals are widely used in various industrial and consumer products due to their resistance to heat, water, and oil. Common applications include food packaging, non-stick cookware, water-repellent fabrics, and firefighting foams. The durability of PFAS, while useful in products, means they persist in the environment and the human body, earning them the nickname ‘forever chemicals’.
Key Findings of the Bluewater Study
Bluewater’s research team collected tap water samples from three London locations: Harrow, Heathrow, and Battersea. These samples were analysed for PFAS content by an independent bio-analytical testing group. The results were alarming:
- Harrow: The water sample showed PFOS levels of 14 nanograms per litre (ng/l), which is 1.4 times higher than the maximum limit proposed by the Royal Society of Chemistry (RSC).
- Heathrow and Battersea: Both locations also exhibited concerning levels of PFOA and PFOS.
According to the RSC, the UK’s current regulatory infrastructure is not up to par with international standards. For example, under Sweden’s new drinking water regulations, the contamination levels found in London would exceed the acceptable limits by 550%.
Health Risks of PFAS Contamination
Exposure to PFAS has been linked to a range of serious health issues, including:
- Cancer
- High cholesterol
- Thyroid disease
- Liver damage
- Asthma and allergies
- Reduced fertility
- Birth defects
- Delayed development
The Need for Improved Regulatory Standards
Dr. Ahmed Fawzy, Bluewater’s Chief Research Scientist, expressed deep concern over the findings. He noted that the current PFAS thresholds in the UK are confusing and inadequate. Dr. Fawzy called for local and national health authorities to urgently reevaluate and tighten these levels by reducing the maximum guideline from 100 ng/l to 10 ng/l.
The RSC has also highlighted that the UK is falling behind other developed nations in establishing safe thresholds for hazardous PFAS chemicals in tap water. The need for statutory PFAS monitoring and regulatory standards is critical to protect public health.
Conclusion
The discovery of high levels of PFAS contaminants in London’s drinking water is a wake-up call for stricter regulatory measures and immediate action. These chemicals pose significant health risks, and without adequate regulation and monitoring, the public remains at risk. It is crucial for regulatory bodies to implement more stringent standards to ensure the safety and wellbeing of all residents.
