    • Drinking water Testing

Drinking Water and fresh air are the unavoidable reasons for life. More than 70% of human body is composed by water. But unfortunately, only 3% of water available across the globe is fresh water and only half of that is available to humans. In developing countries like India, population growth combined with industrial development is hard pressing on water demand resulting in the shrinkage of water table.

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