A high level of fluoride in drinking water can be dangerous for human health. A research team led by Simon Lewis from the University of Bath’s Centre for Sustainable Chemical Technologies has developed simple water test to detect the level of fluoride in drinking water. This is a simple color-changing test and will help to prevent from a bone disease.

High levels of fluoride are found in drinking water sources in parts of India, China, East Africa, and North America. The levels of fluoride are regularly monitored and controlled by water treatment systems in developed countries. But, in some parts of India, people are using unprocessed water from wells, which is contaminated with high levels of fluoride.

Researcher Simon Lewis said that, they have created a molecule that simply changes a color and detects higher level of fluoride in Drinking Water rapidly. The test does not require any water testing lab and trained operator to carry the test. It is a low cost disposable test strip and anyone can use it easily. The new research published in the journal Chemical Communications stated that, this simple color-changing test detects high levels of fluoride quickly and selectively.

As the quality of Drinking Water is always been an issue of concern amongst common people and government, Maharashtra government initiated a project to set up a laboratory to test the quality of water, which is funded by the World Bank (WB).

Benefits of Water Testing Labs:

 In Early days, drinking water was tested only either on receiving complaints or in case of disease outbreak but now because of this new facility of 30 water testing labs, it is compulsory to test the water quality twice in a year. One scheduled of water testing will be done after the monsoon, as there is a highest chance of water contamination.

Till now, there are very few water testing labs in the Maharashtra. And, only hospitals were carrying out testing which is not sufficient for a state. But, now these new water testing labs will check quality of water based on the 18 factors, which also includes checking of concentration of fluorides, chlorides, and potash.

According to test conducted by Eenadu Newspaper, it is found that a water samples contains mixture of bacteria which are:

  • Deadly bacteria and other harmful impurities
  • Contained E-coli, a faecal bacteria found in the intestines of humans and animals, that causes diarrhoea.
  • Hazardous contaminants including pseudomonas, salmonella and staphylococcus.

These water samples were unfit for human consumption.

Let’s Know the Mandatory Processes for Packaged Drinking Water as Per the BIS:

The Bureau of Indian Standards (BIS) has decided that water must be subjected to processes called Pressure Sand Filtration, Activated Carbon Filtering, Reverse Osmosis, Ozonisation and Ultraviolet Treatment before being packaged and sold. Even a perfect water purifier can purify water but creates other problems as water purification which is much more than just removing impurities and reverse osmosis process removes impurities with most of the calcium and magnesium essential for good health. So, the purified water must also be “Remineralised” to bring back the minerals.

Due to increased demand for Packaged Drinking Water, many local small units are running water plants without the mandatory approvals from the BIS as well as Food Safety and Standards Authority of India (FSSAI). While it may need an investment of up to Rs. 20 lakh to run a legal and hygienic water plant, but many illegal water plant unitsare into the business with just Rs. 2.5 lakh with some sort of equipment that pollutes more than purifies the water.

#How to identify if your Packaged Drinking Water is safe?

Consumer should check whether it is properly sealed or not and details like manufacturing date and batch number.

       Here are the Steps:

  1. Click on the ‘status of licenses’.
  2. Type license number that follows the letter CM/L.
  3. Click on ‘report’.

If the details in report are the same as what you see on the container of the Packaged Drinking Water then it is genuine certification.

But if any fake water unit is using the ISI certification and other details of a branded company on his containers then it is very difficult to identify whether the water is safe or not. It is one of the humongous scam as it plays with human lives…
