Drinking Water Testing Lab

 

Safe drinking water and fresh air are the unavoidable needs of any living being. More than 70% of the human body is composed of water. But unfortunately, only 3% of water across the globe is freshwater and only half of that is available for human consumptions. In developing countries like India, population growth combined with industrial development is hard pressing on water demand resulting in the shrinkage of the water table.

The shrinking water table, bad industrial waste management practices, and improper sanitation are responsible for the deteriorating quality of drinking water. The most essential requirement to ensure good quality drinking water testing availability is, conduct regular testing of drinking water.
