Bladder cancer linked to THMs in UK tap water
Bladder cancer linked to chlorine by-products in UK & European drinking water.
Breaking news from scientists confirms what we at The PureH2O Company have been saying for decades: impurities, pollutants and contaminants in UK tap water are associated with risks to human health – including the development of bladder cancer.
Research by the Barcelona Institute for Global Health (ISGlobal), published this month in Environmental Health Perspectives, estimates that 1 in 20 cases of bladder cancer in the UK can be linked to the presence of trihalomethanes (THMs) in tap water. (Evlampidou, 2020)
Fortunately, PureH2O tap water purifiers remove THMs to protect your health.
What are THMs?
THMs are by-products of the chlorine disinfection process used by most municipal water treatment plants in the UK and Europe. Chlorination has been used since the 1900s and is an effective disinfectant that reduces illness from water-borne pathogens (Do, 2005).
However, there is a growing body of research from Europe and North America that shows that long-term exposure to chlorine by-products THMs is associated with an increased risk of bladder cancer. (Evlampidou, 2020)
We’ve always linked the presence of pollutants such as THMs with degenerative health problems, and this recent study appears to substantiate the claims we’ve been making.
UK suffers one of highest rates of bladder cancer attributable to tap water THMs.
Researchers analysed tap water monitoring data from 26 European countries and found that the UK was one of 9 European countries where maximum THMs concentration recorded exceeded the permitted limits of 100 micrograms per litre of water.
The study estimates that the UK suffers the second highest rates of bladder cancer cases attributable to THMs, at 20.7%.
“Spain (22.6%), the United Kingdom (20.7%), and Romania (16.0%) accounted for the largest estimated number of attributable cases.” (Evlampidou, 2020)
Other European countries were estimated to have much lower rates of bladder cancers attributable to THMs: Ireland 1.7%, Sweden 1.3%, Germany 0.6%, and the Netherlands 0.1%. The European-wide average across all 26 countries was 4.9%.
Researchers recommend changes to water treatment & distribution.
Although researchers admit that there have not yet been enough large-scale studies to definitively prove a causal relationship between THMs and bladder cancer, they warn:
“our results suggest that current THM exposures in the European Union may lead to a considerable number of bladder cancer cases that could be avoided…” (Evlampidou, 2020).
The study recommends changes to water treatment and distribution protocols. If relevant parties agree to this, how long will that take? And do you want to continue drinking tap water in the meantime?
What can regulators do about this?
Even if regulators were quick to take action to reduce THMs from chlorination, they would have to use other disinfectants, which bring their own health risks. As the authors of the recent ISGlobal study explain:
“Disinfectants are highly reactive by definition, and any one of them will lead to the formation of [disinfection by-products] DBPs (Hua and Reckhow 2007). Most of them are not regulated, and many are considered carcinogenic and/or genotoxic and have been associated with bladder cancer (e.g., nitrosamines) (Richardson et al. 2007).” (Evlampidou, 2020)
In other words, whatever chemicals are used to disinfect tap water, their by-products are associated with bladder cancer.
Further tap water contaminants also associated with various cancers.
“Whatever their concentration, the presence of microplastics, nitrates, fluoride, pesticides (including the slug poison metaldehyde), heavy metals, cocaine and other drug residues, flame retardant (2D4) and countless other compounds can only have one effect on human health, leading to degenerative illness.”
We believe there are no acceptable levels of pollutants, contaminants and impurities in the water you drink.
What can I do to protect my health?
Jug filters may slightly improve the taste of tap water and somewhat delay the build-up of scale in your kettle, but that’s about it. You won’t want to opt for bottled water because of its massive environmental burden and the fact that it may be even more contaminated by certain substances than tap water.
The safe, effective and sustainable way to protect your health is to use a PureH2O Reverse Osmosis tap water purifier. Our technologically advanced purification systems remove chlorination by-products THMs – and more – from tap water for your total peace of mind.
Reverse Osmosis water purification.
It’s not as complicated as it sounds.
PurityPro water purifiers typically fit in the cabinet under your kitchen sink. They work quietly and efficiently, day in day out, to remove up to 99.99% of all contaminants and impurities found in UK tap water, including THMs.
“The water is fresh, pure and means we don’t have to buy bottled water.” – Paul.
“I’ve had a RODI system from the PureH2O Company for 18 years and I can only praise the PureH2O team for their ability to maintain the quality of water it produces with just one annual service visit. The taste is just brilliant.”
How to order your tap water purifier.
We offer purchase outright, rental options or 0% finance with repayments spread over 12 months. Our team of specially trained engineers install your system and service it annually to ensure it continues to protect your health for years to come – and our extended 10-year Parts & Labour Cover (subject to Service Agreement) offers total peace of mind!
