One page of the book can provide 100 liters of clean water, enough for one person's needs for a month, she said.
Waterborne illnesses, including cholera and malaria, kill 3.4 million people a year, with many of the victims under the age of five, and is especially prevalent in rural areas with little access to potable water. But Dankovich's testing found the Drinking Book largely eradicated e-coli bacteria, a key cause of infection, in contaminated water.
The book serves an educational purpose as well, with information about contaminated water written on the pages using food-grade ink.
"The water in your village may contain deadly diseases but each page of this book is a paper water filter that will make it safe to drink," is one of the messages.
Dankovich hopes to soon use more pictures instead of words, however, to work around the issue of illiteracy. She eventually hopes to use the book as a way of also teaching people how to read.
Determining a price for individual pages or the book itself would largely depend on who it's being sold to, whether it's large-scale aid organizations or villagers themselves, she said, adding that sheets of paper could be sold for as little as pennies.
