Nitrates In Drinking Water Increase The Risk Of Colorectal Cancer

Nitrates In Drinking Water Increase The Risk Of Developing Colorectal Cancer

What has been suspected for years has now been confirmed: the presence of nitrates in drinking water increases the risk of developing a common form of cancer, even at rates below the current ‘safe’ levels set by the World Health Organisation and followed by the UK Drinking Water Inspectorate.

Researchers at Aarhus University in Denmark carried out the largest epidemiological study of its kind (1) and found a positive correlation between long-term exposure to nitrates in drinking water and the development of colorectal cancer, one of the most common cancers in Denmark and the most frequently occurring, worldwide.

Nitrates are naturally present in soil and water at unproblematic levels – excessive levels are caused by the contamination of waterways by human activity including industrial and agricultural pollution. Nitrates are a component of agricultural fertilisers and the UK has guidelines for reducing fertiliser run-off into rivers and streams:

farmers are supposed to avoid spreading on slopes, in wet weather and during winter”. (2) 

But it’s known that in some parts of the UK, even where river catchment areas have special conservation status,

huge quantities of slurry and poultry manure are spread on farmland and… the rules and guidelines governing how this should be done are invariably broken”. (3).

Excessive levels of nitrates negatively impact the health of rivers and streams; they cause unchecked algae growth, which depletes the water of oxygen and makes the reproduction and survival of fish, aquatic insects, wildlife and plants difficult or impossible.(4) The risk to human health occurs because once entering the body, excessive nitrate levels interact with normally occurring amines and amides and convert into carcinogenic N -nitroso compounds.

The World Health Organisation recommends nitrate levels of 50 mg per litre of drinking water, a standard that Denmark, EU countries and the UK authorities follow.

Problematically, the Aarhus study found that colorectal cancer risks are associated with “concentrations far below the current drinking water standard”(5); in people exposed to the highest concentrations found in the study (9.3 mg per litre water) a 15% greater risk of developing colorectal cancer was identified, compared to those exposed to the lowest concentrations found (1.3 mg per litre water). 

The researchers report: “we found statistically significant increased risks at drinking water levels above 3.87 mg/L, well below the current drinking water standard of 50 mg/L”. (6)

As a result, Professor Torben Sigsgaard from the Department of Public Health at Aarhus University warns:

“the drinking water standard ought to be lower in order to protect against chronic health effects” (7). 

Clearly, current drinking water standards are not safe. But you don’t need to wait for the World Health Organisation and UK water regulators to take action, you can protect your health today by installing a Pure H2O tap water purifier in your home, workplace or venue.

Our technologically advanced reverse osmosis (RO) tap water purifiers remove up to 70% of nitrates and, when coupled with de-ionisation, our RODI water purification systems remove 99.99% of naturally occurring impurities and man-made contaminants including microplastics, hormones and medications, petrochemicals, lead and heavy metals. Our RODI purifiers also remove 100% of disease-causing micro-organisms, pathogens and viruses or your complete peace of mind.

Our drinking water purification systems not only protect your health, they are also an environmentally friendly option. Compared to drinking bottled water, our purifiers reduce plastics use and waste, carbon footprint, food miles and save you money, too. Pure H2O purifiers last longer than others on the market, they are water efficient and contain recyclable components.

Our purifiers are designed specifically for treating UK water whether from public supply (tap water) or private water supply (bore holes, wells, etc).

We’d like to help you protect your health. Call us today to discover which of our tap water purifiers is best for you and to book installation by one of our specially trained engineers at a time that’s convenient to you: 01483 617 000.

Out and about? Visit these venues to enjoy Pure H2O pure water.

We recently heard from our friends at Hello Love on Southampton Row that they not only use Pure H2O in their juice bar and tea house, but that they also offer glasses of our pure water free of charge to anyone undergoing treatment for cancer [more about the inspiration behind the Hello Love Foundation below]. So, we thought we’d start compiling a list of everywhere that you can drink Pure H2O pure water when you’re out and about.

Firstly, a reminder of what Pure H2O pure water is and why you might want to choose it over other waters. Our clever reverse osmosis water purifiers remove all the impurities and contaminants found in tap water, resulting in pure water which tastes amazing, doesn’t compromise your health, and means you can take an environmentally responsible approach to enjoying water – compared to drinking water from a plastic bottle.

Of course you can ask us to install a tap water purifier in your home, office, cafe, studio, restaurant, AirBnB – anywhere you want unlimited healthy, safe, delicious water on tap – and you can either rent or buy outright.

But if you’re not quite ready to take the plunge*, or if you’re out and about and feeling thirsty, here’s where you can find pure water on tap (and do tell the lovely people behind the counter that the Pure H2O Company sent you!):

Hello Love  62-64 Southampton Row, London WC1B 4AR

Hello Love’s organic juice bar and tea house (pictured above) uses Pure H2O pure water and always lets anyone undergoing cancer treatment have a glass of pure water free of charge. That’s because of their personal experience – founded by Jane Hutchinson of Hello Love design consultancy, after she was diagnosed with breast cancer at age 35, the Hello Beautiful Foundation aims “to achieve a better understanding of breast cancer and in the process educate the community on the benefits of living a healthy, non-toxic lifestyle”. Pure H2O water is free from the myriad of pesticides, hormones and heavy metals found in tap water, and supports anyone choosing to eat, drink and use non-toxic products whether they’re dealing with a diagnosis or simply looking after their health.

Planet Organic the UK’s largest fully certified organic supermarket, stores stock organic groceries, health and beauty products, as well as delicious prepared food and Pure H2O pure water on tap. Founder Renée Elliott says: “children absorb impurities at 10x the rate of adults, so it’s important they avoid toxins in food and water”.

Myth Busting: Alkaline Diet has no effect on cancer

We’ve been running a series of myth busting articles on alkalinity because there’s a lot of confusion, disinformation and frankly outright nonsense online about acidity and alkalinity when it comes to pure water and nutrition – usually peddled by people trying to sell you an alkaliser for RODI pure water or convince you of the importance of the latest fad diet.

So we were really pleased to see this fact-based, common-sense article in The Independent written by experts Cancer Research UK, confirming what we’ve been saying: the food you eat and the water you drink does not affect the acid / alkaline balance or pH of your body.
