Activity (Hands-On)Grades 5 - 7
From Lake to Tap
How is water treated to be safe to drink?Copyright https://en.wikipedia.org/wiki/Aerated_water#/media/File:Aerated_tap_water.jpg
In this activity, students use a tutorial on the U.S. Environmental Protection Agency's website to learn about how surface water is treated to make it safe to drink.
Every community's source of water is unique since it may come from rivers, lakes, aquifers, snowmelt or some combination. Engineers design unique treatment plants, depending on the quality of the water that enters the plant, to remove the harmful visible and invisible particles from our drinking water.
After this activity, students should be able to:
- Describe technologies developed by engineers for drinking water treatment.
- Assess the importance of each process used to treat water.
- Identify which process takes place at each point in a water treatment facility.
