Safe drinking water, a global concern

The safety and accessibility of drinking water is a global concern. The World Health Organisation (WHO) reports that 80 percent of diseases are waterborne. Contamination from the geological formations (termed geogenic contamination) is the major source of groundwater contamination.

Harvesting rainwater effectively
An innovative project makes rainwater harvesting easier and more effective in certain areas of Mewat village with increased groundwater salinity.
Posted on 15 Feb, 2018 01:25 PM

One of the major causes of deterioration of water quality is the increase in overall salinity. Total hardness and the presence of materials like fluoride, nitrate, iron, arsenic, and toxic metal ions determine salinity levels in groundwater. With the demand for groundwater growing rapidly, its exploitation is also accelerating which causes depletion.

The innovation was introduced in a government school building in Untka village located in Mewat district of Haryana.
