Chlorinated water- Is it good for us?

Chlorine has been widely used as a disinfectant for drinking water across the world. This has been a worldwide approved chemical since
1904. Chlorination has been done to prevent water borne diseases like typhoid, cholera and dysentery.
Chlorine acts as an oxidizing agent when dissolved in water which kills the microorganisms through the process of oxidization.

Chlorine and hydrolysis products are charged neutrally so that they can easily penetrate the surface of the pathogens found in water.
It is then able to disintegrate the walls of the cells of the pathogens making them nonfunctional so that they either die or are not able to multiply. However the point to be noted here is that certain bacteria like e coli and coliform are still found in chlorinated water
Chlorine in water is itself is not harmful unless the water is treated with high doses. However, the disinfection byproducts (DBP)
generated from the chemical reaction of chlorine with organic matter produces two most common compounds namely trihalomethanes (THMs)
and haloacetic acids (HAAs).
According to world health organisation, the small amount of chlorine in water upto the specified limits are considered acceptable for

lifelong human consumption.
But the level of contamination even after chlorination to the water reaching the faucets is not specified. It is always advisable to
be safe than sorry. The studies have also been conducted over the negative impact of chlorination on over exposure or in long run.

Its side effects:

A long term exposure to high doses of chlorine can lead to various diseases which can vary from minor headaches to cancers.
One of the form of THM is chloroform which is carcinogenic- cancer causing. But it is possible if it is consumed in very high doses.

Due to long term exposure to chlorine and its byproducts the chances of bladder, colon and breast cancer increases manifold.

The high exposure can also lead to kidney and liver damage, immune system dysfunction, disorders of the nervous system, hardening of
the arteries and faster ageing process

The studies on effect of chlorine has also identified chlorine and THMs as one of the reason of stillbirths and bones related diseases
in infants. The chlorine has its role in heart attacks in elderlies and infants.The effect of exposure to chlorine can be seen on hair
and scalp as well. It can lead to dry and flaky skin, dandruff and hair fall.
One may complain about flu like symptoms, headaches and skin rashes due to exposure of chlorine.The exposure to chlorine in swimming
pools are equally harmful as the level of dissolved chlorine in pool water is higher which can lead to various diseases.

How to get chlorine free water

Although chlorine act as a disinfectant in water and has played a vital role in controlling epidemics, but nowadays various options
has been developed to remove these germs from water and thus the need of chlorine is minimized.One of the option to pass the water through any form of carbon. The filtration of water through activated carbon can remove chlorine from water
The ozonation can also help to remove germs and chlorine from water

The UV filtration not only helps to kill the microorganisms from the water but also removes chlorine from water thus water which has
taste and odour due to chlorine is also purified.These options are good to choose from as they do not include any chemical in the
purification process and also removes other harmful chemicals and microorganisms from the water
