The Truth Behind Tap Water: Is It Bad For Your Health?

Drinking bottled water is a luxury nowadays. Studies show that bottled water costs 3000 times as much as tap water. To put it simply, the usual costs of tap water are around $0.02 per gallon, while bottled water has an average price of $0.64 per gallon, depending on its brand. 

And because bottled water is not affordable for everyone, people prefer to consume tap water instead. 

But how confident can we be of its quality?

Contaminants Found In Tap Water

Some of the most common contaminants found in tap water include lead, which can produce permanent brain damage in children, and PFOA, which has been linked to cancer. 

The quality of tap water mostly depends on the area where you live. In some cities, tap water may contain high levels of contaminants, while in other areas it may have a low amount of pollutants. 

Therefore, even if tap water passes through a municipal water treatment plant before it reaches your house, in its composition can also be found substances such as arsenic, chlorine and fluoride. 

Excessive consumption of each of these the substances listed so far can have harmful effects on your health. 

  • PFOA - Also known as Perfluorooctanoic Acids, these synthetic compounds accumulate over time in your body and decomposes very hard, which is why they are toxic to the human body. PFOA substances are usually used to manufacture other products and can easily get into your water if you live near a factory.
  • Lead - Most of the time, lead gets into the water that people consume due to corrosion of pipes and fixtures. Lead is also harmful to adults. If exposed to a high level of lead, people can suffer from cardiovascular effects, increased blood pressure and incidence of hypertension, decreased kidney function, or even reproductive problems.
  • Arsenic - This is a naturally occurring mineral present in drinking water in all 50 states. Excessive exposure to arsenic from drinking water can cause bladder, diarrhoea, vomiting, lung and skin cancer as well as harm to the skin and lungs.
  • Chlorine - This is the main cause of the unpleasant taste and smell of tap water. Consumed in higher doses, chlorine can cause diarrhoea, vomiting, itchy skin, and other harmful side effects. However, chlorine levels up to 4 ml/L are considered safe in drinking water.
  • Fluoride - This substance is found in all waters. In fact, fluoride is now used in the public drinking water supplied to about 3 out of 4 Americans and its main purpose it's to prevent tooth decay.  

Numerous studies in recent years based on water quality have linked fluoride from drinking water to many health issues such as dental fluorosis, high blood pressure, thyroid problems, severe acne, or even cancer. 

And now comes the big question – Is it safe to drink tap water? Well, as you have seen, there are a variety of contaminants in tap water. 

Even if these are only present at levels that do not pose high risks for human consumption, there are cases where drinking tap water is contraindicated.  Therefore, new-borns, pregnant women, the elderly, people with a weakened immune system or chronic diseases should avoid consuming tap water. 

Tap Vs Bottled Water 

The differences between bottled water and tap water are not noticeably big. Even if Americans invest money in bottled water because they think it is healthier than tap water, this is not exactly true. 

Many of them prefer bottled water over tap water claiming that it has a better taste and smell. Yet, in a 2018 blind test, people could not tell the difference between bottled and tap water.

To better highlight the similarities between the two, we'll reveal something you probably didn't know - some brands of bottled water actually use ... tap water. Therefore, 64% of bottled water comes from municipal tap water sources. 

If you are reading this article and wondering if it is safe to drink tap water, we are here to tell you that not even what you find on store shelves will keep you away from health risks because bottled water is NOT free of contaminants. The water you see in the good-looking bottles at the supermarket may contain microplastics – some chemicals that can also harm your health.

Perhaps the biggest difference between the two is that bottled water has a major impact on the environment. In fact, a million plastic bottles are bought around the world every minute. This number will jump another 20% by 2021 and will create a huge environmental crisis.

This means that if you drink bottled water you will only spend money that you could use on something else, accumulate more chemicals in your body other than those already existing in tap water and also contribute to environmental degradation.
