If you are using a reverse osmosis (RO) water purifier and feel content that the water you drink is safe, there is news for you.

Reverse osmosis is the best available option for purifying borewell water with high levels of nitrate. “It is better to get the water tested before opting for reverse osmosis. If the water does not have nitrate content, a normal purifier will serve the purpose,” said M.V. Shashirekha, retired chief chemist from the Department of Mines and Geology.
