No “One Size Fit All” Solution For Water Contamination

Experts working in the area of water quality management have emphasized that there can be no “one size fit all” solution to tackle the problem of water contamination as the nature and extent of pollution varied across locations.

A recent directive of the National Green Tribunal (NGT) has asked Center to regulate the use of reverse osmosis (RO) technology for water purification.

The green tribunal had asked the central government to ban its use, where the total dissolved solid in the water was less than 500 mg per litres, and ensure that water recovery was more than 60 per cent and the rejected water was used for washing cars and other such purposes.

In addition, NGT had urged for creating public awareness on the adverse effect of demineralization of water on the users.

Participating in a panel discussion organised by the Council of Scientific and Industrial Research (CSIR), the experts stressed the need for proper testing of the quality of the water before taking any step for its purification to ensure selection and adoption of a technology that was most appropriate for the situation.

“The world is faced with a crisis of water. The situation is particularly acute in India as it has access to only four per cent of the world’s fresh water resources, even while housing 18 percent of its population. We need appropriate solutions”.
