The TDS level, according to an official in 27 odd bore wells, has gone beyond 2,000 ppm. Several of the borewells have been shut in recent times, the official said. “Presently, various physical and chemical qualities such as TDS, PH, Nitrate, Iron, and Chloride are overshooting the permissible limits. We are taking adequate measures, including placing iron removers, before pumping the water to households,” said another official.
