PITTSBURGH — Can bacteria-killing filter paper packaged in the form of a convenient book help people around the globe gain access to clean drinking water?

That’s the hope of Theresa Dankovich, postdoctoral research associate in the civil and environmental engineering department of Carnegie Mellon University, who has developed “The Drinkable Book.”

In the works since 2008 while Dankovich was a doctoral student at McGill University in Montreal, the book generated buzz and national and international publicity at the American Chemical Society meeting in Boston last week.

The first page makes the mission clear: “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.”

According to the nonprofit, 840,000 people die each year of water-related disease, and one in nine people lack access to safe water. The filter is designed to eliminate water-borne bacteria; it killed 99.9999 percent in lab tests.

In the prototype, each page has two filters, separated by perforations. The top has a message in English; the bottom the same message in the local language. Users can tear off a filter, place it in a holder above a clean container and then pour water into the filter. The optimum holder design for effective and easy use is still being developed by University of Cincinnati design graduate Luke Hydrick, now with Continuum, a design consultancy.

The length of time for water to filter through to the container varies, depending on how much debris is in the water. Each page can filter up to 26 gallons.

Dankovich initially was working on making antibacterial paper, which has many applications such as food packaging and medical masks.

“I just was intrigued by the idea of just a cheap water filter. I wasn’t necessarily thinking of any particular market. I was trying to focus on the science. Then I started to read more about the water crisis. I thought this could be a great method to clean water for a lot of people out there,” she said.

In 2013, she did field testing in Limpopo, South Africa. The following year, she did testing in northern Ghana and this past summer in Bangladesh. People from a nonprofit partner organization, WATERisLIFE, have done testing in Haiti and Kenya.

More than a year ago, Dankovich formed a nonprofit called pAge Drinking Paper. The idea for turning the drinking paper into a book came from a New York designer, Brian Gartside, then at DDB NY and now at Deutsch, after he read about her filter paper work.

With help from CMU students, Dankovich makes her filters by hand. She begins with big sheets of filter paper that are thick — almost like cardboard — and chemically treated so they don’t fall apart when water is poured on then.

She then treats the paper with silver nanoparticles, which turn the paper a shade of orange. The nanoparticles are the key to eliminating bacteria.

A silver salt is applied to the paper, and the paper is baked for 10 or 15 minutes in a commercial oven at a Friendship church. She takes the sheet home, pours distilled water on it to take off excess material, hand blots it to soak up extra water and lets it dry in her basement. Then the papers are sent out for binding and printing using food-grade ink on a letterpress.

Dankovich and her students also are experimenting with copper nanoparticles, which can have a similar anti-bacterial effect. Copper is 100 times cheaper than silver.

She figures about 2,000 pages — each with two filters — have been made so far. Some have been used to make about 50 books. The challenge is finding ways to bring production up to scale. The hope is that ultimately each filter could be manufactured for 10 cents or less.

“Poverty just often reduces people’s ability to buy basic things. Water purification sometimes can be a luxury for people, which sounds horrible, but that’s just how it is,” she said.

The Drinkable Book isn’t ready to go on the market yet. More testing, including trials by users, lies ahead. A campaign on the Internet site Indiegogo seeks $30,000 for pilot scale tests in two villages for about a month. With $150,000, the technology could be tried in about a dozen villages, each for a month or two. Government research grants also are being sought.

“I have gotten a lot of emails requesting books. I wish I could, but we’re not quite there yet,” she said.

One application is a book made with pages of the filter paper that can be ripped from the book to filter water as needed. (Bob Donaldson/Pittsburgh Post-Gazette/TNS)

Eric Holder

The failure of major federal voting rights legislation in the Senate has left civil rights advocates saying they are determined to keep fighting—including by suing in battleground states. But the little bipartisan consensus that exists on election reform would, at best, lead to much narrower legislation that is unlikely to address state-level GOP efforts now targeting Democratic blocs.

“This is the loss of a battle, but it is not necessarily the loss of a war, and this war will go on,” Eric Holder, the former U.S. attorney general and Democrat, told MSNBC, saying that he and the Democratic Party will be suing in states where state constitutions protect voting rights. “This fight for voting rights and voter protection and for our democracy will continue.”

“The stakes are too important to give up now,” said Damon Hewitt, president and executive director of the Lawyers’ Committee for Civil Rights Under Law, which for years has operated an Election Day hotline to help people vote. “Our country cannot claim to be free while allowing states to legislate away that freedom at will.”

In recent weeks, as it became clear that the Senate was not going to change its rules to allow the Freedom to Vote Act and the John Lewis Voting Rights Advancement Act to pass with a simple majority, there have been efforts by some lawmakers, election policy experts, and civil rights advocates to identify what election reforms could pass the Senate.

“There are several areas… where I think there could be bipartisan consensus,” said David Becker, executive director of the Center for Election Innovation and Research, in a briefing on January 20. “These areas are all around those guardrails of democracy. They are all about ensuring that however the voters speak that their voice is heard… and cannot be subverted by anyone in the post-election process.”

Becker cited updating the 1887 Electoral Count Act, which addressed the process where state-based slates of presidential electors are accepted by Congress. (In recent weeks, new evidence has surfaced showing that Donald Trump’s supporters tried to present Congress with forged certificates as part of an effort to disrupt ratifying the results on January 6, 2021.) Updating that law could also include clarifying which state officials have final authority in elections and setting out clear timetables for challenging election results in federal court after Election Day.

Five centrist Washington-based think tanks issued a report on January 20, Prioritizing Achievable Federal Election Reform, which suggested federal legislation could codify practices now used by nearly three-quarters of the states. Those include requiring voters to present ID, offering at least a week of early voting, allowing all voters to request a mailed-out ballot, and allowing states to start processing returned absentee ballots a week before Election Day.

But the report, which heavily drew on a task force of 29 state and local election officials from 20 states convened by Washington’s Bipartisan Policy Center, was notable in what it did not include, such as restoring the major enforcement section of the Voting Rights Act of 1965, which was removed by the U.S. Supreme Court in 2013. It did not mention the Electoral Count Act nor growing threats to election officials from Trump supporters.

“This won’t satisfy all supporters of the Freedom to Vote Act, but this is a plausible & serious package of reforms to make elections more accessible and secure that could attract bipartisan support,” tweeted Charles Stewart III, a political scientist and director of the MIT Election Data and Science Lab. “A good starting point.”

The reason the centrist recommendations won’t satisfy civil rights advocates is that many of the most troubling developments since the 2020 election would likely remain.

Former president Donald Trump

(Reuters) -The prosecutor for Georgia's biggest county on Thursday requested a special grand jury with subpoena power to aid her investigation into then-President Donald Trump's efforts to influence the U.S. state's 2020 election results.
