The backbone of a modern society is clean, available water. Without clean water, production plants falter due to corrosion, lack of cooling capability, or unsteady supply. However, in many if not most parts of the world, water safety is a challenge. This presentation gives an introduction to some of these challenges, trying to ensure clean, available water and the consequences of unfiltered, dirty water. The focus is on what you can do to help solve this challenge. You, the technologist, the hacker, the lockpicker, the everyday person, can help devise better systems to solve some of these challenges. Geeks Without Bounds works around the world setting up solution-oriented hackathons that put participants in the driver's seat working together on technology issues to make the world a better place.
