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.

Safe drinking water, sanitation, and hygiene (WASH) are the essential components to lead a healthy life. Correct, consistent, and continuous practices of WASH behavior, particularly hand hygiene can help prevent infections and spread of diseases.

One of the principal risks to public health is the lack of access to safe drinking water. The Millennium Development Goals by the World Health Organisation (WHO) focus on the target of halving the proportion of people without access to safe drinking water.

Panna Tiger Reserve located in the Vindhyan mountain range in Madhya Pradesh is spread over 542.67 square kilometres. The climate in Panna is warm and temperate.

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.

What is the exact problem as regards groundwater salinity, fluoride and water scarcity in Mewat, Haryana? Is the area underlain with saline groundwater aquifers? What is the status of surface water in the area? Can it not reduce dependence on groundwater?
