Is our bottled water safe for drinking?

We usually buy cool bottled waters. Have you noticed a expiry date on water bottles? Our bottled water have a large number of micro plastic, which may cause a health issue. The reuse of the single use plastic bottle is a health hazard on a long term purview. Lets this post to know the details.

We buy and drink mineral water bottle water considering it to be safe, pure clean compared to tap water. How safe is bottled water? Why does bottled water have expiry date? Why bottled water taste different after a period of time than regular water? I want to address in this article

Recently researchers from State University of New York said that the pure and clean bottled water we know, completely depend upon its actual pervaded with tiny particles of plastic that go completely unnoticed. So how does the water get contaminated?

Water packed in bottles gets contaminated with almost invisible micro plastic particles leftover and that are most likely to flow or escape into the water during packing process. It is assumed that if someone drinks 1L of bottle water in a day, that person would be consuming as high as 10000 piece of micro plastics per year. Therefore the major contamination is due to bottle itself or due to cap.

Plastic is mainly composed of polyethylene terephthalate(PET) and polypropylene which are used to manufacture bottle caps. Researchers claim that 93% of water bottle samples from 11 popular brands in nine different countries including India are suffused by tiny pieces of plastic, around 10.4 micro plastic in each liter. On average 65% of micro plastics are not fibers, they are actually fragments. None of the sample were found completely free of plastics, there are micro plastics in the density of 10 to 10000 per litre.

Does it mean that tap water is completely safe to drink?

Well no tap water contain micro plastic but on a smaller scale. Tap water is much safer than bottled water. Bottled water contains twice the micro plastic present in tap water. Some researchers claim that single use plastic bottle do not contaminate as no statistically amount of micro plastic were found.

How dangerous is bottled water?

It is still unclear how bottled water can affect human health as micro plastics who are widely found in everything from fish, shellfish, honey, sea salt to tap water. While a few micro particle stick in intestinal wall, other might be absorbed buy intestine tissue through body's lymphatic system. Some others can be taken up by body's hepatic portal vein which is responsible for carrying blood from pancreas and intestine to liver.

Around 90% of ingested plastic is excreted by human body naturally. But in our long term the potential impact of plastic on human health could be a botheration. Micro plastic can increase the risk of certain kind of cancer, health condition like autism and can even cause lower sperm count.

In the hot summer days we opt for cool bottle of water. We just open the seal and drink it without noticing the expiry date. Well, water never expire then what does the expiry date on the water bottles signify? Actually the plastic bottle in which water is packed gets expired. PET will eventually begin leaching chemicals into the water and thus affecting its taste and smell.

Therefore manufacturers should clean the water bottle before filling the mineral water. We should reduce the use of single use plastic bottle. Always look at the expiry date of water bottle before purchasing.

Another good article about drinking water. Bottled water is as such unsafe but the reuse of these plastic containers make it more unsafe. So it is better to crush and throw the bottles rather than leaving them as it is. Another problem I have noticed is the filling of water bottles with ordinary water and selling them as mineral water. Once I have seen in a place the water was just filtered through and packed in bottles.
These plants producing mineral water are to be regenerated after collecting a certain amount of mineral water and in case of RO plants the filter is to be changed. But these processes are not done correctly in some small mineral water bottling plants. So we should be careful in purchasing the water. It is better to go for standard companies like Kinely or Aqua Fresh. In my opinion, the best water is the tap water which should be boiled and cooled before drinking.

Plastic water bottles contain various chemicals. The major ones are Bisphenol A, Polyethylene terephthalate and Phthalates. Bisphenol A negatively affects reproductive and endocrine systems. It increases the chances of brain, breast, ovary and prostate cancer. It can even result in asthma and hyperactivity. Polyethylene terephthalate bottles are not good for health as they are contaminated with saliva, fecal matter, and residues of food matter. Phthalates are known to cause male sterility, cancer in the liver and testicular atrophy.

We will never know what type of plastic got used to manufacture water bottles. There is no certain way through which we the consumers will come to know that the plastic used in the manufacturing process is contaminants and chemicals free or not. Bottled water is nothing but water from the tap. Why not use tap water instead of purchasing the water bottles. Filtration process installed in our homes will efficiently filter the tap water making it good enough to drink.

Tap water, before making its entry in our taps, is held in huge containers and passed through large pipes. Hygiene and safety concerns are definitely raised in such a scenario. Water is treated with arsenic, chlorine, and fluoride and also with many other chemicals which ultimately ensures that it is healthy and clean. We then wonder that why don't we drink tap water directly as it is treated with so many chemicals after all. The reason is the chemical residues that are left out after the treatment procedure. Even in micro amounts, these chemicals should not make an entry in our body. Over a period of time, they keep accumulating in our system and cause major health-related troubles. Worse situations arrive if we are using the same water for cooking purposes and showering with it.
