Extension Activity: Engineering Pure Water
Many disease epidemics are spread through polluted water. Many countries outside of
the U.S. do not have the same access to clean drinking water, which increases the
spread of certain diseases like cholera and typhoid fever.
For Homework, research different methods that engineers develop to create water
purifications to reduce the spread of disease.
 Identify 3 different methods to purify water
 Explain each method and countries that use that method
 State which method you think is the most effective and explain why (answer on
the back of this paper or on a separate piece of looseleaf)
