Water is a necessity and we have been told we need to drink at least 8 cups of water to keep our body hydrated. According to the President’s Cancer Panel1, there are many ways which we can reduce environmental risk towards cancer. Drinking loads of water and your choice of water are two ways to reduce your risk towards cancer. We have outlined the differences among tap, boiled and filtered water and which one is the best option for your household.
Is tap water safe to drink?
According to Pubic Utilities Board (PUB), the tap water that runs from source to the tap in your home undergoes comprehensive robust sampling and monitoring programme to ensure that tap water supplied is safe for drinking2.
In a 2015 water quality report3 by PUB, it was found that there are still significant levels of heavy metals and dissolved solids in the water. Some of these include aluminium, barium, boron, bromate, chlorate, chlorine, chlorite, chloroform, chromium, copper, cyanide, chloride, fluoride, iron, monochloramine, manganese, molybdenum, nickel, nitrate, nitrite, sulphate and silica.
- Chloroform is carcinogenic, which means it can cause cancer. They are frequently used as a disinfectant in water treatment and used in labs for experiment. When handling chloroform, you will need to wear gloves and masks to ensure minimum exposure. Some of the side effects when inhaled or consumed are liver and kidney problems, depression and cancer4.
- Aluminium is been widely linked to liver toxicity, alzheimer’s disease and breast cancer. While the concentration of aluminium in tap water is within the standards of World Health Organization (WHO), the effects of aluminium consumed in small quantities over a long term period is unknown. Apart from the low concentration in water, canned food, pots and pans and aluminium foils are common sources of aluminium in our modern lifestyles5.
- Chlorine is commonly found in swimming pools to disinfect the water and is also widely known as a health hazard. When it reacts with other substances in water, chlorine produces toxic and cancer-causing byproducts and can often lead to sleepiness, slowdown of brain activity, liver and kidney problems and heart diseases. Similar to aluminium, the effects of long term consumption is unknown6.
- Fluoride was added to water due to poor dental hygiene in the past. Within the last 15 years, research has revealed that fluoride primarily works when applied topically and directly onto the teeth, hence there is no need for fluoride to be chemically added to our water supplies. In addition, fluoride is now considered to be a neurotoxin which indicates that we should avoid fluoride at all cost7.
Is tap water really safe to drink?
What about boiling water?
In short, boiled water may kill the remaining micro-organism and bacteria which chlorine and other chemicals missed so it may be safer to drink. Boiling water can also reduce the concentration of chlorine, but the water has to be cooled for about 20 minutes before consumption. However, boiling water does not remove the other contaminants that was added to water or picked up while running through your water pipes. If you live in an old estate, your old and aged water pipes could contain much concentrated contaminants as well.
So, what is the best solution?
According to a President’s Cancer Panel1 report, drinking plenty of water or liquids may reduce the risk of bladder cancer by diluting the concentration of cancer-causing agents in urine, thus helping to flush them through the bladder faster. Since drinking so much water is critical, quality of water is also important so as to not introduce any carcinogen contaminants back into our body. It was also suggested that filtering your water will reduce your exposure to carcinogens and hormone-disrupting chemicals hence it was essential to have a water filtration system8.
A filtration system will ensure that your household gets access to safe drinking water. Reverse osmosis can remove many contaminants, which activated carbon can remove chlorine, chemicals, heavy metals and bacteria. Most filtration systems that require installation may cost a lot and do not remove some of the water component. Fluoride is one of the hardest chemical to remove from water and most filtration systems do not remove fluoride. Some filtration systems will also require you to install at the water source which makes it inconvenient.
Water filter that removes chlorine and up to 99% of fluoride
At Wellness Within, we aim to stock the most affordable, cost effective and toxin free products. After doing much research, the Waters Ace Bio 1.5L Alkaline Water Filter Pitcher that we stock is one of the best in the market that does what other filters do and on top of that, removes up to 99% of fluoride and turns your tap water into alkaline mineral water. That’s additional benefit!
Boiling water alone does remove some chlorine but it’s too simple a process to purify your water. We would highly recommend to definitely use a water filter to provide drinking water around your house, in order to effectively remove the contaminants and hormone-disrupting chemicals.
