How safe is your tap water?

Have you ever wondered what exactly is in your tap water, and how safe it is to drink on a daily basis? I share some findings from Nutritionist, Amelia Freer’s, recent blog about tap water.


If your New Year Resolution is to drink more water – the government recommends 6-8 glasses per day – it’s worth thinking about where this water is coming from (a ZeroWater filter may be a good investment). Although tap water in the UK is generally safe and highly regulated, there are still things we should be aware of. And if you choose to drink bottled water, choose glass not plastic every time. I was interested to read Nutritionist Amelia Freer’s recent blog about tap water. She says:


A source of debate – but as long as levels of fluoride are less than 1.5mg/litre it doesn’t pose a risk to health.


There are no proven negative health effects from hard water – in fact, it made add calcium and magnesium to your diet. Those with eczema may find it useful to use a water softener system for the bath or shower but this may be a case of trial and error.


Older houses built before 1970 may have underground lead pipes which can leach into your water. However, the World Health Organisation has set a limit of 10 micrograms of lead per litre of water.


In the UK low levels of chlorine are added to the water supply to keep it free from bacteria and other microbes. If you’re concerned about chlorine, use an activated carbon filter.


Although river water downstream of waste water discharges may have detectable levels of ethynyl oestradiol, filtration and disinfection by water treatment plants is effective at removing this from our water supply.


Reverse osmosis filters remove all the solids and minerals from water. However, it is not generally recommended to drink RO water, unless all the appropriate minerals, in the right quantities, have been added back. Another common type of filter is the water softener. While this may be useful for transforming hard water to soft, it’s not recommended for drinking or cooking as it replaces calcium and magnesium with sodium, thus introducing more salt to the body.

A ZeroWater filtration jug removes up to 50% more dissolved solids than a Brita filter. To find out more, visit their website here
