This section of the water purification tool kit is a compilation of images, tables, quotes, poetry, and other resources aimed to help you design an interesting and effective written or oral presentation for your audience. The use of visuals, stories, and other colorful devices can be very helpful in communicating difficult concepts and in keeping your audience engaged. You may want to select items included here for your presentation or simply use them to inspire ideas of your own. These presentation aids provide a base of materials from which we intend to continually expand. It is our hope that people who take from this collection will also leave behind items they develop so that others may use them. If you would like to contribute to the materials available here, please send an email to esahq@esa.org and reference "water purification presentation aids" in the subject line.
