By: Indo-Asian News ServiceUpdated: May 27, 2015 12:08 pm The reverse-osmosis water purifier at home seems to be a benign invention, allowing people to drink clean, healthy water. But now scientists are warning that rampant use of the RO technology could pose a serious threat to public health. One of the most popular water purifying technologies in India, the RO process is efficient in terms of filtering out toxic substances like arsenic and fluoride, especially in areas where groundwater is heavily contaminated. Simultaneously, though, RO systems, at both household and industrial levels plough back concentrated amounts of these substances back into the aquifers. Experts suggest that regulations are needed to stop the unchecked use of RO, or at least the disposal of the stuff left behind after filtering. “What we found with our survey is that industrial firms, like bottled-water ones, and households have no way out but to put it back into the soil and aquifers,” said Saradindu Bhaduri, Assistant Professor, Centre for Studies in Science Policy, School of Social Sciences at Jawaharlal Nehru University (JNU).
