Creating a ripple effect: How one Georgia Southern professor is using community-sourced materials to improve clean water accessibility

Dec 12, 2024

Turning on the tap for a drink of clean water may seem like part of an everyday routine for many. Yet, for countless communities—even here in the U.S.—this simple act remains a daily challenge, with each glass or clean drop of water far from guaranteed. One Georgia Southern University professor is working to change that.


Thirty percent of the Navajo Nation population lacks access to clean drinking water. Lewis Stetson Rowles, Ph.D., assistant professor in the Department of Civil Engineering and Construction in the Allen E. Paulson College of Engineering and Computing at Georgia Southern University, is working to increase access to clean water for this community and beyond by engaging with locals to understand how materials used in traditional cultural practices can be transformed into life-changing solutions.


“My first trip to the Navajo Nation as an undergraduate student was a really eye opening experience for me,” Rowles said. “To realize that there were people within the U.S., in our own backyard, who lacked clean water is what inspired my whole career in research and education.”


Establishing trust was an important challenge to overcome for Rowles and his fellow researcher and mentor Navid Saleh, Ph.D., professor of environmental and water resources engineering at the University of Texas at Austin.

“Years of uranium mining left the mineral-rich area and the connection with the Navajo community polluted,” Rowles said. “It has been a decade-long effort to build community relationships, understand the issues and develop potential solutions specific to the needs of the Navajo Nation.”




Finding solutions specific to local needs and cultures is key to their implementation and success according to Rowles.


“We have to work with communities to truly understand the issues and collaboratively develop functional solutions because locals are the people who understand the problems the best,” Rowles said. “I don’t believe that there’s a one-size-fits-all solution. For technologies to really be sustainable, we need to understand if they’re going to work in a specific location, which means we need to develop community-specific solutions.”


Working with the community is important for more than just understanding the issue at hand. When thinking about big-ticket issues, like clean water, Rowles said that it’s easy to fall into the trap of thinking about large-scale, infrastructure-based solutions. But some of the most immediately effective and impactful solutions happen on a much more intimate level.


“Centralized distribution systems take a long time to build, they’re also very costly,” Rowles said. “The need for clean water is dire in many communities, so point-of-use technologies are great because they can be adopted quickly. They also bring power to the people in a way, because technologies can be developed with local materials, like we’re doing here with clay and pinyon resins for ceramic filters. This can create immediate solutions to water contamination issues.”


Rowles, who specializes in environmental engineering, worked with members of the Navajo community to discover how the process of creating traditional pottery can help solve the problem of clean drinking water at a local level for families. Deanna Tso, a third-generation Navajo potter, has been integral to this process to ensure that the novel solutions don’t detract from traditional practices.

“If you’ve ever climbed a pine tree and gotten sap stuck on your hands, you know it’s very sticky,” Rowles said. “The Navajo people have been using this sap for centuries to waterproof pottery and baskets. Meanwhile, one of the biggest limitations to the use of silver nanoparticles for water treatment is the immobilization of those particles. We used this local resin to coat the nanoparticles, keeping them in place and extending the lifetime of the filters while still allowing them to kill bacteria. It also acts as a really unique barrier that prevents silver poisoning by stopping the silver from interacting with other compounds that would inhibit the dissolution of silver nanoparticles into silver ions which kill bacteria.”


By working together to integrate new technologies into existing traditions, Rowles and his partners are one step closer to changing the lives of many in the Navajo Nation. Their hope is that this knowledge will be used to expand access to potable water to more parts of the world.

“While we started working with Deanna on a very specific pine tree sap, the more we’ve researched, we’ve seen there are similar pine and conifer trees throughout the continent, even into Mexico, that have been used by indigenous groups for centuries,” Rowles said. “This means that this research has much broader applications across the world, particularly in areas that lack centralized water treatment systems where people go and collect water from distant sources or wells, bring it back to their house, and then treat it at the household level.”


The extension of this knowledge begins by sharing it, which is precisely what Rowles’ team has done over the last year. They published their research Integrating Navajo Pottery Techniques To Improve Silver Nanoparticle-Enabled Ceramic Water Filters for Disinfection in October 2023 and shortly thereafter began working with PBS NOVA. Their work will now be shared as part of a documentary series highlighting engineers working to positively change the world.


“The Navajo Nation is just one area impacted by lack of access to clean water,” Rowles said. “Around 1.5 million people across the U.S. lack indoor plumbing and many more rely on wells and septic systems that are often aging or failing, leading to sanitation concerns. There are a lot of great organizations and a lot of great research working to address sanitation issues abroad, but I hope this research can open people’s eyes to the fact that this is a local problem, too. Don’t take it for granted that you’re able to turn on the tap and have safe, clean water, because that is not true for a lot of Americans and for much of the world.”

Expert Q& A: ‘The Pope is also a monarch’

Kathleen Comerford, Ph.D., professor of history at Georgia Southern University, specializes in Catholic history in the 16th and 17th centuries. She is also an associate editor for the Journal of Jesuit Studies, which focuses on the work of the Society of Jesus (Jesuits), a religious order within the Catholic Church. Pope Francis was the church’s first Jesuit pope. With the global significance and rarity of the conclave, Comerford answered frequently asked questions about how the conclave works, how the conclave process has evolved over time, and what the passing of a pope means for the Catholic Church and the world. Question: What does the passing of a pope mean for the world? Comerford: Multiple things! First of all, there are 1.4 billion Catholics in the world scattered in many different countries. The pope is a unifying figure for all of the Catholics. He represents something immediate in the sense that he’s the head of the church and is a recognizable figure. The pope is also a monarch. I was just talking with my classes about this. He is the head of the government of the Vatican City State, which is the smallest independent state in the world. It has a very long history itself. Pretty much everybody who lives in Vatican City works for the Vatican. The pope is one of the few elected monarchs in history. He is responsible for financial and political decisions, and he has ambassadors around the world as a result of his role in global policy. Question: How is a new pope selected? Comerford: The College of Cardinals will meet for an election called a conclave, and they actually stay in a dormitory-like place in Vatican City for it. They are sequestered from the public, and they take some time to meet, pray and vote. The cardinals aren’t supposed to be sitting around talking about who would be a really good pope, but we don’t know whether they do because they’re sequestered and nobody is supposed to talk about it. They will likely take a vote on the first day, but that’s not required. Every subsequent day, they can take a maximum of four votes; two in the morning and two in the afternoon until a candidate gets a two-thirds majority. Question: What does the voting look like? Comerford: There are ballots, and the cardinals write their preferred candidate on the ballot, and then they put their vote in a chalice. To count the votes, there’s a group of three people who are in charge of counting and then announcing the results to the fellow cardinals. There are 252 cardinals, but only 135 of them are eligible to vote because anyone over the age of 80 is ineligible. The procedure where only cardinals can elect the pope dates from 1059. The secret ballot and the two-thirds majority requirement is from 1621. The sequestration for the process dates from 1271 because they argued about who the new pope would be for two years and nine months; a total of 33 months. And so, they decided that the only way to make sure that this didn’t happen again would be to create this scenario with the cardinals locked in a room with a key. Question: When one of the candidates receives a two-thirds majority and becomes the next pope, how will it be announced? Comerford: Well, this is kind of fun, because they have four votes every day until one of the candidates receives a two-thirds majority. After they take the votes, the papers used to vote are burned. How the news is shared to the crowds outside is based on the color of smoke. If the smoke is black, that means no one received the majority and there’s no new pope yet. If there’s white smoke, it means there’s a new pope. This practice really only dates to the early 19th century. At first, it was just if there was smoke, there was no pope; if there was no smoke, then there was a pope. In 1914, they changed this aspect of the election so that black smoke means “no pope” and white smoke means “new pope.” Question: It’s expected that the next pope will be one of the cardinals in the room when they vote, yes? Comerford: Yes, but it doesn’t have to be. There have been a lot of popes, but in the last 200-300 years, there hasn’t been somebody who wasn’t in the conclave that was elected. Theoretically, they could nominate somebody who’s not a cardinal and the whole room could say, “yes, that’s the person we want as pope.” However, they don’t vote by acclamation anymore. They stopped doing that in the 19th century. Question: Pope Francis appointed 108 of the cardinals, so that’s a total of 80% of those eligible to vote for the next pope. How likely is it that we see a pope similar to the late Francis, considering he provided the electorate for his successor? Comerford: First of all, he deliberately went out and created cardinals in places where there had never been cardinals before. And he didn’t do that by saying, “I’m going to find somebody who’s like-minded to me.” He just said, “There are a lot of Catholics in Myanmar and they’ve never had a cardinal. So I’m going to make sure that there’s a cardinal now.” Most of these new cardinals are in places like Rwanda, Cape Verde, Tonga, Myanmar, Mongolia and so on. So these are non-European cardinals. Now, less than 40% of the voting cardinals are European. So to speculate on how similar they are to Francis, you have to break down what Francis was. There has been his entire pontificate about how he’s the first American pope, but his parents were born in Italy. He didn’t grow up speaking Italian, but it was a dialect of Italian as well as Spanish, because he grew up in Argentina. He was the most European you can get and still be an American. Another part of the question is, will the new pope be somebody who is of a similar mind to Francis in terms of his governance, which was very devolved. He introduced this idea of “synodality,” which is about fairly consistent communication with groups of people. Pope Francis was not particularly monarchical or hierarchical. There is also the aspect of his thinking that leans more to the left than the right on a number of social issues like immigration, women’s rights, the rights of minorities and immigration. He opened a lot of conversations, which the very right leaning portions of the church have been very uncomfortable with.

Rural health documentary earns Peabody Award for Georgia Southern professor

Georgia Southern University Professor Matthew Hashiguchi has won a Peabody Award for his documentary, “The Only Doctor,” which focuses on rural health and the services provided by a single doctor in southwest Georgia. The Peabody Awards are prestigious accolades in storytelling across television, radio, streaming and other digital mediums. Categories for winning a Peabody include journalism, social video, interactive documentary, gaming and more. The nearly hour-long feature received the award in the Public Service category, which recognizes projects that address or respond to public health concerns, enhance public engagement or educate the public. For Hashiguchi, the award represents a personal and career accolade. “This award isn’t just a professional achievement, but also represents a moment in my life where I became a father,” said Hashiguchi. “I started filming right before my first daughter was born, and finished right after the second. While this award is an incredible acknowledgment of my work, it means even more to me as a priceless moment from their childhood.” The documentary focuses on Karen Kinsell, M.D., the sole physician serving 3,000 citizens in Clay County, Georgia, near the Georgia-Alabama border. The film spotlights the plight of a community in need of medical assistance and the dedicated doctor fighting to keep her clinic’s doors open. Hashiguchi delves into Kinsell’s sacrifices for her clinic’s operations, revealing her commitment to her patients. “Dr. Kinsell gets calls at home at all hours of the day and night,” Hashiguchi said. “She, at times, has had to pay the bills from her own bank account. But I’d say the biggest sacrifice is that she’s a doctor who does not have breaks.” The final cut of “The Only Doctor” is a bit different from the angle Hashiguchi took when he began work on it several years ago. He initially started the project to better understand the risks associated with maternal health care and childbirth when he and his wife were expecting their first child. Through his work, he learned of a more complex issue of health care access in rural communities. The documentary first premiered on the PBS program Reel South and is now available internationally on Al Jazeera’s documentary series “Witness.” Hashigchi’s work earned him a 2019 Gucci Tribeca Documentary Fund award and a 2021 American Stories Documentary Fund award from Points North Institute. The film’s world premiere took place at the 2023 Hot Docs International Documentary Film Festival in Toronto, Canada, and was awarded Best Documentary Feature at the 2024 South Georgia Film Festival, Best Feature at the 2023 Newburyport Documentary Film Festival and Award of Merit at the 2023 University Film and Video Association Conference. His rise to media prominence wasn’t on his radar early in his academic career. He described himself as a “C student,” and still sees himself as that young boy struggling with math and science courses. With one of the nation’s highest media honors, he can show his students new paths to success as well as the skills it takes to win a Peabody. “I want my students to know how I failed and know that I struggled,” he said. “I tell them that if they want to excel, they really have to put in hard work. That’s very much who I am now as I devote myself to these films.” If you're interested in learning more and want to book time to talk or interview with Matthew Hashiguchi then let us help - simply contact Georgia Southern's Director of Communications Jennifer Wise at jwise@georgiasouthern.edu to arrange an interview today.
