The World Water Monitoring Challenge (WWMC) is more about public awareness than it is about conducting science, but if you have concerns about your local water quality and want to get involved in a global movement, this might be the project for you.
To participate, you need to purchase a test kit, and then do regular water sampling at a local freshwater source from March 22 (World Water Day) to December 31. A single kit contains enough material to do as many as fifty tests.
You can register at the main site and enter your data any time; there is also a large resource section at the site with handouts, lesson plans, promotional material, and backgrounders suitable for teachers, activists, homeschoolers, and the press.
The goal of the WWMC is to educate and engage citizens in the protection of the world’s water resources, and make people more aware of how their activities affect water quality.
