World Water Monitoring Day

World Water Monitoring Day is dedicated to water quality control. It is celebrated on September 18th. Water is one of the main components for human life. Despite being able to survive for several weeks without food, the first symptoms of dehydration appear after the first day. After 2-3 days without water, death can occur.


The American Clean Water Foundation (ACWF) introduced this holiday in 2003. It is engaged in research on sources of drinking water supplied to the population. The event was originally scheduled to take place on October 18. However, given its international status, it was moved to September. In many northern countries, cold already sets in in October and water bodies freeze.

During World Water Monitoring Day, thousands of researchers from different countries take water samples and analyze them. This approach makes it possible to ascertain the safety of water for the population and to keep annual reports showing the change in the composition of water over time.

The organizers of this massive water control event were constantly changing. It is currently sponsored by EarthEcho International. The main goal is to raise public awareness about water quality and inform about subsequent checks.
