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). The WB officials are also trying to understand the current requirements of the project.
The functioning of the new laboratory will be handled by Groundwater Survey and Development Agency (GSDA). The Pune-Head quartered lab will worked as centralized system and co-ordinate with over 30 labs,which are to be established under the same project.
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.
As per the news articles in money control, Maharashtra Govt. is taking initiative to check bromate levels in water brands. As many activists has raised the issue of high bromate levels in Packaged Drinking Water, India’s food regulator Food Safety and Standards Authority of India (FSSAI)sent order to Maharashtra FDA to test samples of all Packaged Drinking Waterbrands like Bisleri, Kinley, Aquafina, etc..
According to the sources, The Maharashtra FDA will collect 20-25 samples of Packaged Drinking Water for testing bromate levels. The levels for Bromate are now defined at 10 microgram per litre in Packaged Drinking Water. The FDA has to report to India’s food regulator FSSAI in the next one-two months. This news is also confirmed from Bisleri.
Packaged Drinking Waterplant uses ozonisation to disinfect water which transforms the bromine into bromate ions. Bromate is a chemical which can cause carcinogenic effects, reduce weight and affect renal function. It is compulsory for all the Packaged Drinking Water plants to test bromate levels in Packaged Wateraccording to the Bureau of Indian Standards.
A Simple Bicycle based purification system is invented by a new Japanese entrepreneur-scientist. You can install the system on a bicycle , take the bicycle anywhere you need , start pedaling it & produce pure water. This way you can even drink the swimming pool water , they say. Watch the Video. The company is also looking for partners. Contact them if you are interested.
