The new, media-rich e-book from QUEST, Engineering Is Cleaning Poop from Drinking Water, tells the story of how a team of scientists and engineers at Stanford University designed an inexpensive water purification device that attaches to the water pumps used by people in Dhaka. The device dispenses chlorine in just the right amount, killing microbes and making the water safe to drink. The book explains the team’s process of researching solutions, designing the device, testing it and making improvements (using a 3D printer!). The book also contains a career spotlight video of Amy Pickering, the lead engineer on the project. And, there’s a look at the various ways water treatment plants in the United States treat water so that it’s safe for us to drink.
