If you ask Google “Can I drink tap water in the UK?”, you will see water.org confirms that UK tap water is safe to drink. But recent studies show that UK’s safe level for toxic PFAS is really high and toxic PFAS levels of some of the water samples exceed European Food Standards Agency tolerable limit.
What is the safe limit for PFAS in the UK? UK Drinking Water Inspectorate says that PFAS chemicals should be less than 100 ng/l (nanograms per liter) in drinking water. But European Food Standards Agency’s tolerable limit is 2.2ng/l. One of them should be wrong, right?
Can I drink tap water in the UK?
Water.org says that British tap water is one of the best. But scientists are not sure about that.
PFAS are chemicals that can be found in many products such as non-stick pans, food packaging, carpets, furniture, firefighting foam. PFAS have been linked to a range of diseases like liver disease, cancer and pregnancy complications.
University of Greenwich and Manchester Metropolitan University tested 45 tap water samples. The study shows that 25 samples have PFAS chemicals and 4 of them contain more than 10 ng/l.
Professor Roger Klein, a chemist and PFAS expert, said: “It underlines that this stuff is everywhere and that it’s in drinking water. It’s ridiculous that the UK Drinking Water Inspectorate has a level of 100ng/l before action is taken.”
Rita Lock-Caruso said that “We’re finding health effects at lower and lower concentrations – in the single digits.”
PFAS Found in British Otters
A research shows us that 50 otters that found dead in between 2007 and 2009 has PFAS chemicals in them. Most of them had 12 different types of PFAS chemicals in their livers. The same result was achieved when they tested otters that died in between 2014 and 2019.
Even though the amount of PFAS in the livers of otters is not the cause of their deaths, it clearly shows that UK waters are contaminated with PFAS.
UK Drinking Water Inspectorate should consider the tolarable limit of PFAS in drinking water. 100 ng/l can’t be accepted for sure.

Toyota Motor temporarily stopped production at 11 of its factories after the 7.4-magnitude earthquake in northeast Japan. Toyota offered its condolences to the families of those who lost their lives in the violent earthquake the previous night in Japan.
Ukraine-Russia war is getting more intense every day and an attack to a nuclear plant may cause a nuclear explosion. Also, Russia may use a nuclear weapon. The safest place to be during a nuclear attack is a fallout shelter.
