A new study reveals alarming levels of harmful chemicals in rainwater worldwide, raising health concerns.

Rainwater, a vital natural resource that replenishes groundwater and provides drinking water in many regions, has now been found to contain dangerous chemicals in nearly every location across the globe. Researchers from the University of Stockholm have discovered the presence of “forever chemicals” in rainwater, revealing that their concentrations have reached unsafe levels.

These harmful substances, known as per- and poly-fluoroalkyl substances (PFAS), are particularly concerning because they break down extremely slowly, earning them the nickname “forever chemicals.” According to the study, the levels of PFAS in rainwater have surpassed recommended safety guidelines, with serious implications for human health.

What are ‘forever chemicals’?
PFAS are synthetic chemicals commonly used in products such as non-stick cookware, stain-resistant fabrics, and food packaging. These substances are now being found in rainwater, making it unsafe to drink in most parts of the world, including the UK. The study highlights an alarming decline in the acceptable levels of PFAS in drinking water, particularly in the United States, where the safe limit for one of these chemicals, perfluorooctanoic acid (PFOA), has been reduced by an extraordinary 37.5 million times over the past 20 years.

Ian Cousins, the lead author of the study and a professor at Stockholm University, explains that under the current guidelines for PFOA in drinking water, all rainwater would be considered unsafe for consumption.

What impact could this have on our health?
Exposure to PFAS has been linked to several serious health issues, including fertility problems, cancer, and developmental delays in children. Dr. Jane Muncke, managing director of the Food Packaging Foundation in Zurich, has called for stricter regulations on these chemicals. She emphasised the importance of holding the industries that produce and use PFAS accountable for the harm caused, particularly as millions of people face the risks of contaminated drinking water.

While the study sheds light on the growing concern over PFAS contamination, experts stress that immediate action is needed to protect public health and secure clean water sources for future generations.

Water companies issue advice to consumers as the country faces prolonged dry weather and possible drought conditions.

Water companies across the UK are warning customers to be mindful of their water consumption as the country grapples with dry weather conditions, raising concerns over potential droughts.

The National Drought Group recently elevated England to a “Prolonged Dry Weather” status, signalling a critical step toward an official drought declaration. The Met Office reported that July 2022 was the driest July for England since 1935, with England receiving only 35% of its usual rainfall for the month and Wales 53%.

In response to these conditions, several water companies have implemented hosepipe bans, while others are urging customers to conserve water. Below are updates from key water providers across the UK:

– Anglian Water: Operating in the driest region of the UK, Anglian Water reported receiving only 20% of the usual rainfall in July. Although reservoir levels remain stable at 80%, the company is monitoring river levels closely and encouraging customers to conserve water.

– Dwr Cymru Welsh Water: Welsh Water has introduced a temporary hosepipe ban in Pembrokeshire, following the driest conditions in the area since 1976. This ban affects over 2% of the population it serves, and the company stresses the importance of ensuring enough water supply for the coming months.

– Northumbrian Water: Currently, Northumbrian Water does not foresee any need for restrictions this summer. The company is committed to managing environmental resources responsibly and closely monitoring water levels.

– Severn Trent: Severn Trent has not imposed any hosepipe bans for over 27 years, but continues to monitor water levels closely. The company has provided customers with tips to reduce water waste, including using a bucket and sponge to clean cars and watering plants with a can in the evening.

– South West Water: South West Water has not yet introduced a hosepipe ban but is advising customers on ways to conserve water. If the situation worsens, restrictions may be implemented in the future to protect water resources.

– Thames Water: Thames Water has activated its statutory drought plan, which includes steps to manage water use. The company has already begun promoting water-saving tips and is preparing to implement a temporary use ban if needed.

– United Utilities Water: United Utilities has no plans to restrict water use but continues to encourage customers to be mindful of their water consumption.

– Wessex Water: While no restrictions are currently in place, Wessex Water encourages all customers to use water responsibly, ensuring that resources remain available for everyone.

– Yorkshire Water: Yorkshire Water is urging customers to reduce water use by avoiding unnecessary tasks such as washing cars or watering lawns. The company is also working to fix leaks to prevent further wastage.

As the UK faces ongoing dry conditions, water companies are emphasising the importance of responsible water use to help prevent the need for more severe measures in the future.
