Dr. Teri Dankovich, a postdoctoral researcher at Carnegie Mellon University, is leading on one of the more interesting and revolutionary projects in Africa, called the “drinkable book”.

Sub-Saharan Africans have to endure an array of prominent environmental issues, one of which is finding drinkable water and Dankovich is heading a research campaign that may solve just that issue.


Drinkable Book

The pages of the “drinkable book” contain nanoparticles of silver or copper which kills bacteria in the water being filtered through.

The drinkable book provides information about water safety but its content doesn’t scratch the surface of the importance of its other uses. Dr. Dankovich’s team performed test trials on 25 contaminated water sites among Ghana, Kenya, Haiti, South Africa, and Bangladesh.

“The resulting levels of contamination are similar to US tap water, the researchers say. Tiny amounts of silver or copper also leached into the water, but these were well below safety limits,” – reports BBC.

Dr. Dankovich explains that one page can clean up to 100 litres of water, according to her tests. The use of an entire book could filter someone’s water supply for an estimated four years.

In total, 83 million people globally don’t have access to clean drinking water. From a macro perspective, the drinkable book could have a much greater impact than expected as the issue it solves expands outside of Africa.
