“Is tap water safe?”
This is the thought most of us have when drinking water from the tap or drink tap water at the restaurant / bar when we have no choice.
There is so much confusing and contradictory information about tap water.
This is why I think it’s about time someone looked at all the evidence and gave some kind of conclusive answer or at the very least clarify some of the myths and misconceptions.
Tap Water vs. Bottled Water
The first thing to note is that both forms of water are safe to drink although bottled water is likely to have gone through a further filtration process. Some people consider that bottled water tastes better then tap water and doesn’t create limescale if used in your kettle.
However, the biggest disadvantage of bottled water is the cost both in terms of finances and to the environment. It is thought that imported water brands use 300 times the CO2 emissions per litre when compared to the energy used to create tap water. It also takes around 162g of oil and 7 litres of water to manufacture a 1 litre bottle.
The other side of this are pitifully low recycling rates. For instance, some 14 billion plastic bottles still end up in the UK landfill every single year.
What Is In Your Glass of Tap Water?
Like most people, you probably take your glass of water for granted and assume it contains nothing but… erm water, right? After all, water is one of the few things we consume that contains zero calories so it doesn’t contain anything right? Wrong.
Did you know that even the cleanest-looking glass of water isn’t necessarily clean? Sadly, the biggest dangers lurking in the water you drink can not always be smelled with your nose, tasted or even seen. Invisible impurities in your drinking water can come from many different places.
What’s In Your Drinking Water?
Of course, there are many natural minerals and nutrients that organically occur within water but most drinking water (especially tap water) have had many things added to them.
In most cases these chemicals have been added to clean and purify the water, but in some cases government authorities add things to tap water to improve the health of the population e.g. fluoride.
The following is a sample list of some of the things that are sometimes added to the water supply:
- Liquified chlorine
- Calcium hydroxide
- Sodium silicofluoride
- Aluminium sulphate
Even if the water leaves the source in a reasonably clean state, you must remember that water travels through pipes and the cleanliness of the tap itself is pivotal to the cleanliness of the water you receive from the tap. Especially tap outlets which suffer from both rust and limescale.
What’s in Tap Water?
Tap water is treated with many chemicals that kill bacteria and other harmful microorganisms. The following list is a list of some of the typical content that you might find in tap water.
Typical Tap Water Content
- Trihalomethanes (THMs).
- Fluorine compounds.
- Salts of:
Water Quality: Contaminants in the Pipes?
In rare occasions, your tap water could become contaminated due to damage in the water supply line.One of the most dangerous problems that could occur is lead getting into the water from pipes. Even ”lead-free” pipes can contain around 8% of lead.
“The best way to avoid lead contamination entering your tap water is to only use water from the cold tap and to let the water run for a minute before using it.”
Do this every time you get water for cooking, drinking, filling up the kettle or even making baby formula.
So Is Tap Water Safe To Drink?
It is also the eco-friendly option when compared to bottled water and you don’t have the risk of BPA contamination with plastic bottles.
You are also vulnerable to drinking “hard water” that will create limescale in your kettle or coffee machine.
If any of these is an issue for you then you might want to consider buying a portable water filter jug or installing a home filtering system so you have control of the content and quality of your drinking water.
