History of World Water Monitoring Day

The World Water Monitoring Day was first brought into existence in 2003 by America’s Clean Water Foundation (ACWF). The organization aimed to raise awareness among civilians about the importance of regularly monitoring their water sources. The global outreach program’s date was October 18 initially. October 18 was considered ideal as it would pay homage to Congress’ passing of the U.S. Clean Water Act of 1972. However, ACWF soon realized that some countries would not be able to participate in the World Water Monitoring Day as the water bodies in said countries would freeze during October. Thus, to maximize the number of participants and participating countries, the official date was moved back by a month. Every year, around one million or more people take part in the initiative. Using water testing kits, they test the water for dissolved oxygen, acidity, temperature, and clarity.

Over the years, the sponsors for World Water Monitoring Day have changed consistently. The current organizers belong to EarthEcho International. It is a nonprofit environmental organization, which was founded to honor Philippe Cousteau, a famous oceanographer. The late Cousteau family created the Philippe Cousteau Foundation, but after disputes over the name with the Cousteau Society, the name was changed to EarthEcho International. EarthEcho is involved in many activities including World Water Monitoring Day. Once the day came under their organization, the name was changed to EarthEcho Water Challenge. But no matter the name, the goal of the day remains the same: To educate the masses about water sources and the subsequent safety inspections that should be carried out regularly.
