Lifestyle Desk, Lucknow. Generally people consider water that appears clean and transparent to be safe. But according to experts, mere appearance of water is not a guarantee of safety. There may be chemicals present in water which are not visible to the eye, but can harm health if they reach the body for a long time.

Arsenic, some industrial chemicals and 'forever chemicals' like PFAS present in water are a matter of concern for this reason. Some PFAS chemicals have been linked to a number of health problems, including cancer. At the same time, there is evidence of increased risk of lung, bladder and skin cancer by drinking water containing arsenic for a long time.
How is there danger hidden in clean water?
Let us tell you that many chemicals present in water do not cause any significant change in color, smell or taste. Therefore, it is not possible to determine whether water is potable or not just by looking at the eyes. For this, scientific testing is very important.
Experts are especially concerned about those chemicals which persist in the environment for a long time. PFAS are called 'forever chemicals' for this reason. They have been used in many industrial and consumer products and exposure to them has been linked to several health effects, including cancer.

How true is the claim of the 66 year old rule?
The most important thing to note here is that the claim “66 year old rules are increasing the risk of cancer” is not directly proven in this form. No single 66-year-old drinking water rule has been confirmed in available reliable sources that can be directly attributed to the increase in cancer.
Old rules were made in 1958
According to experts, the acceptable level of nitrate in drinking water was fixed in the year 1958. According to this, the limit of nitrate in water was set at 50 mg per liter. At that time, the decisions were made keeping in mind the Blue Baby Syndrome occurring in children. Let us tell you that Blue Baby Syndrome is a dangerous condition in which the oxygen carrying capacity of the blood is reduced. Due to lack of oxygen, the skin color starts turning blue, which can also prove fatal.
conclusion: It is not necessary that clear looking water is always chemical-free. To know the real safety of water, scientific investigation and adherence to prescribed quality standards is necessary.
