Toxins

Life as we know it depends on water. Yet, we often take it for granted. The convenience of having 24/7 access to clean water can come at a price. Did you know that water discharged from a dishwasher can contain up to 1,000 times the EPA's recommended level for phosphate?

What goes up must come down. And what goes in must come out? We’re talking about the drain, of course.  Every time we take a drink of water, we have an impact on the environment—whether we choose to drink water from the tap, or from a fountain or bottle, our actions have impacts. And what about what we’re sending back down our drains? And not just us—factories and agriculture pollute water for aquatic life and human use downstream. What can you do?

Students all over the country have created dozens of other projects to clean up what comes out and what goes in. The Down the Drain Action Guide and related lesson plans, videos, and other resources will highlight some of those projects, as well as shine light on some of the most important water quality issues. Take a look.

Action Guides

  • Down the Drain

    Down the Drain

    Did you realize that everything you send down the drain—including things that you wash off your body or that first pass through your body—can end up back in local waterways, the ocean, and even the water supply? Use the tools in this Action Guide to investigate what is going down your drain, and to develop and implement a plan to defend your drain (and others) from toxins.

  • Defend Your Drain webinar

     The Defend Your Drain webinar features a panel of experts who explore what is going down our drains, what impact scientists are observing, and how young people can get involved. Hosted by Philippe Cousteau, this webinar was a kickoff to engage students across the nation in Seventh Generation Foundation's Campaign for a Toxin-Free Generation video contest.

Lesson Plans

  • Comparing Levels of Phosphates in Dishwasher Detergents

    Our daily activities have a profound impact on water chemistry. One of the most pervasive chemicals in the products that we regularly use is phosphorus. It’s in fertilizer and cleaning agents. But excess phosphorus in aquatic ecosystems is a serious pollutant. In this activity, students estimate the amount of phosphorus in water discharged from a dishwasher and relate that to the Environmental Protection Agency’s recommended limits on phosphorus in lakes and streams.

  • The Effect of Acid Rain

    It's a common misconception that pollution is caused only by direct discharge of substances into water bodies. Acid rain is a byproduct of sulfur pollution primarily from fossil fuel electrical power plants. In this activity, students learn how a small input of acid rain can change the acidity balance in a body of water.
