Water Survivor Class Lesson: Incorporating the Grand Challenges into the Classroom
Supplying access to clean water is one of the National Academy of Engineering (NAE) grand challenges for the 21st century. The lack of clean water is estimated to be responsible for more deaths in the world than war. About 1 in every 6 people living today doesn’t have access to clean water and double that value is lacking access to basic sanitation. The shortage of water is a factor of the supply not always being located where it is needed. In many instances, economic and political barriers can prevent access to water even in areas where it is otherwise available. In some countries the people discharging toxic contaminants and waste contaminate water supplies. As well as, by arsenic and other naturally occurring poisonous pollutants found in groundwater aquifers. This lesson aims to introduce students to the global crisis at hand and introduce the students to the water treatment process here in the United States.
