When you wake up in the morning and start your daily routine—take a shower, brush your teeth, cook breakfast—do you ever stop to wonder where all that water you’re using comes from? It’s availability (or lack thereof) is certainly not a common worry in the United States, where as of 2005 (the latest assessment of national water use conducted by the U.S. Geological Survey) about 86 percent of the population relies on public water supplies for household use. Turn a faucet handle, and water, the world’s most precious, life-giving resource, is simply there, ready to cool us or clean us or quench us of our thirst, wherever we need it, whenever we want it.

But for how much longer? Climate change, pollution and unprecedented global demand are already threatening the world’s water supply according to a United Nations World Water Development Report released earlier this year. (SciStarter partnered with Discover Magazine, the National Science Foundation and NBC Learn to explore the Future of Water as part of our Changing Planet series.)

In response to these challenges, two international nonprofit organizations, the Water Environment Federation (WEF) and the International Water Association (IWA), partnered up to launch a challenge of their own.

Today, September 18, is World Water Monitoring Day, a key component of the broader World Water Monitoring Challenge that runs from March 22 to December 31. Thousands of people from around the world will use low cost monitoring kits to test their local water bodies for the basic indicators of watershed health–temperature, acidity, turbidity, and dissolved oxygen—and enter their results into a shared online database. It’s not too late to get involved. The program’s administrators hope that participants will not only learn which rivers, lakes, streams and reservoirs supply their communities but also become aware of the unique combination of environmental challenges each one faces.

“These are issues the next generation will have to cope with,” said Lorien Walsh of the Water Environment Federation. “The water we drink today is the same water people have been drinking for thousands of years. It is a finite resource, and we can’t use it if it’s not clean.”

In 2011, over 300,000 people from nearly 80 countries participated in the World Water Monitoring Challenge. Taking clean water for granted might be common in the United States, but it is a luxury people can ill afford in the developing world, where three million people, most of them women and children, die from water-borne illnesses like cholera every year.

“Kids in Kansas can see the data they collected and compare it to the data collected by kids in the Congo,” said Walsh. “There’s a stark difference.”

On September 18, 2011, people around the world will be taking a closer look at their local waterways during World Water Monitoring Day. Join in the project and help figure out whether the freshwater near you is clean.

Clean freshwater is an important resource for people. It keeps ecosystems healthy too. The water flowing through a small stream leads into larger rivers and lakes. All that water flows downhill together. It’s all connected in a watershed. Understanding the health of our watersheds is critical to understanding whether people, animals, and plants are getting the clean water they need. Volunteers with the World Water Monitoring Day seek to make measurements of freshwater to identify the health of the world’s watersheds.

Using a test kit, volunteers figure out what’s in their water. They measure the temperature, acidity (pH), clarity (turbidity), and dissolved oxygen (DO) of water and then report the findings online. The test kit costs $13 plus shipping, or you can use your own water monitoring equipment if you’d like. There are kits available at no charge for participants from low and middle-income countries thanks to support of sponsors. Test kit instructions are available in 17 languages.

Christine Goforth is an entomology Ph.D. student at the University of Arizona. Her research focuses on the aquatic insects of the Sonoran Desert, especially the parental care behaviors of the giant water bugs and using aquatic insects to indicate and manage water quality issues in Arizona.

In July of 2009, a friend and I arrived at a lake to collect water samples for work. We had worked at the lake many times, but something was different that day: several hundred dragonflies were flying over the grass.

We often saw dragonflies, but there were 50 times the usual number and they weren’t in their usual places. We knew something exciting was happening, so we jotted down notes. I returned to the lake twice to record more observations of the swarm and simply appreciate the marvel of nature that I witnessed. Then they were gone.

That experience changed me. I am an aquatic entomologist with an interest in dragonfly behavior, but that swarm captured my attention like nothing else. I needed to know more about it! I looked into the scientific literature to find answers, but discovered that little is known about dragonfly swarms.

Up north, in Washington State’s tranquil San Juan Islands, members of the Kwiáht marine research team are hard at work keeping an eye on local sea life and terrestrial critters. Kwiaht, a word in the Coast Salish dialect, refers to a place that is physically healthy and spiritually clean.

The group hopes to ensure the continued health of the San Juan Island ecosystem by allowing local citizen scientists to participate in ecological research.

Want to volunteer? Contact Kwiaht’s program director to find out how you can become involved as well!

In addition to research and outreach, Kwiaht also aims to help restore terrestrial and aquatic ecosystems by working with public land managers to develop conservation strategies.
