In my opinion, whilst it’s safe, it’s not advisable to drink.

Our bodies are bombarded by toxins every single day; from the air we breathe to the products we use. Tap water is just one of the many ways we can ingest and accumulate toxins in our body. That’s because tap water is treated with a large number of chemicals in order to kill bacteria and other microorganisms.

Here’s a list of just a few of the chemicals:

  • Liquified chlorine
  • Fluorosilicic acid
  • Aluminium sulphate
  • Calcium hydroxide
  • Sodium silicofluoride

Don’t forget that once your water leaves the water treatment plant it travels through pipes, some of which may have been underground since Victorian times. It is almost impossible for the water not to become contaminated by something undesirable. If your house was built before 1970 it’s probably still fed by a lead pipe at the very least from the water main in the street to your stop tap, so there’s every chance of heavy metal contamination.

Over 300 different man-made chemicals have now been detected in British tap water.

A recent study by Brunel University showed levels of benzotriazole and tolytriazole in UK tap water – these chemicals are found in dishwasher tablets but yet are finding their way into our water supply.

Brunel University have also advised there is a staggering amount of pharmaceutical medication in our tap water. These are designed to be stable and long-lasting, which means after they’re excreted and end up in our waste water, a proportion of these pour unaltered through the sewage filtering system and back into our domestic supply.

Studies have also revealed that high levels of the female hormone oestrogen contaminate water supplies as it returns to our waterways from the millions of women on the contraceptive pill or HRT (hormone replacement therapy). It’s being questioned whether this could be linked to our rising infertility issues, in both men and women.

Fluoride is added to around 10% of the UK’s water supply. Its purpose is to help prevent dental decay, but which comes with side effects. The thyroid gland is particularly affected by fluoride exposure because its store of iodine becomes depleted. Lack of iodine depresses the thyroid’s metabolic and immune functions by shutting down production of thyroxine, the thyroid hormone that controls metabolism, resulting in hypothyroidism and lowered immunity. Many countries have now banned fluoride from being used in water supplies because of the health risks.

Research by Birmingham University showed that the chlorination process that tap water goes through to kill germs and dangerous bacteria could be a problem for pregnant women. Researchers found that chemicals formed during chlorination called trihalomethanes (THM) were found to cause a higher incidence of three birth defects; hole-in-the-heart, cleft palate or anencephalus.

Then there is the consideration of pathogens being in the water supply. Coldwater storage tanks supplying public drinking water are regularly checked for harmful pathogens such as Legionella bacteria and E.coli. However, microbiological analysis found that samples taken as standard from the top of the tank are 40% less likely to raise a red flag than samples taken from the bottom. 

Current safety regulations require a sample of water be taken from under the ball valve at the top of the tank for regular microbiological monitoring, although scientists are now calling for the standard safety tests to be changed to look at samples taken from the far end of the tank, where water is likely to be warmer and hold more bacteria-feeding sediment.  

I think I’ll stick to my water distiller for now in view of the above. If you’d like to get the one I use, I’ve put the link under my “products” page.
