Protect our water planet as an EarthEcho Water Challenge Ambassador! Through this unique experience, Ambassadors become community scientists and lead ongoing water quality monitoring efforts through the EarthEcho Water Challenge, a global water quality monitoring program that has engaged 1.8 million participants in over 150 countries.

Water Challenge Ambassadors are a network of youth equipped with the tools and training to lead community science and watershed improvement projects. Ambassadors collaborate and learn alongside their peers, conduct community water monitoring programs with local youth, and use their experiences to take direct action to protect local water resources.

The 2026 Water Challenge Ambassador application period is now closed.

  • Youth ages 14–22
