HTI HydoPack: Clean Water for Disaster Relief The HydroPack Is Like a Capri Sun Pouch for Disaster Relief

For World Water Day: Meet the Capri Sun pouch you simply drop in a mud puddle or contaminated river to get clean, fortified water.

Today is World Water Day. This year's theme is "Water for Cities." Yes, you can still attend all manner of walks, photo contests, screenings, and other events supporting global access to clean water. We've highlighted some noble projects for delivering drinking water in the past, but today we bring you you news of a new technology designed especially for disasters.

The HTI HydroPack is like an empty Capri Sun pouch with powdered nutrients inside. But it's really a filter you can drop in any water source—a swimming pool, a mud puddle, a contaminated aquifer—and eight to twelve hours later the pack has filled itself with potable, fortified water.

The makers, Hydration Technology Innovations, hope communities prone to flooding—like Mudimbia, Kenya, on Lake Victoria where these photos were taken—can stock up on the packs and put them to use in the first days after disaster. Gaylon White is the Director of Design Programs at Eastman Chemical Company. He helped make Eastman makes components for HTI's filter membrane for the HydroPack and participated in a field test in Kenya last month. "In an emergency situation, often times the people are surrounded by water, but they can't drink the water," he says. "This gives them a way of utilizing the water that's right there and making it clean to drink and giving them not only hydration, but also nutrients that get them past the first days."

The first phase of an emergency response situation, the first three to eleven days, are crucial for public health. Before electricity is restored, clean water is shipped in, and medical operations are fully established, people are at the greatest risk of the secondary dangers of disaster. "You have a lot of water borne illness ... dysentary, cholera," White says.

Typically, after this phase, he says, you can get water filtration systems in place, but they need power. So until that happens the current practice is to truck or fly in bottled water. That's a heavy load. HTI estimates that the HydroPack could have saved 90 percent of the cost of shipping water after the earthquake in Haiti because you are just shipping a little pouch with electrolyte powder inside, not the actual weight of the water.

That's the promise of this technology: faster deployment and lower cost to bring water to the people after a disaster. As White explains, it all works through forward osmosis. "Think of water coming up through dirt, the roots of a tree, up through the branches and feeding the fruit ... the hydro pack is using the same forward osmosis process. It's part of nature."

Natural as the inspiration may be, it's still advanced technology considering the packs have a shelf life of more than five years and have to work in pretty adverse conditions. The packs were designed by HTI for military and recreational outdoor use and currently sell for about $4 each, far too expensive for mass deployment in the developing world. [UPDATE: HTI tells GOOD that for "humanitarian bulk orders" the price per pack is as low as 80 cents per pouch.] "Seldom do third world nations benefit from our technology, our material and design expertise. This project combines all three," White says, proud that his company, Eastman, is trying to adapt this product for disaster usage.

White says the cost of production has to come down to about 75 cents per pack if it's going to be sold to international relief agencies. Entrenched habits of hauling bottled water need to be adjusted too. HydroPacks and other filtration products, such as the LifeStraw Family, are complements to the existing clean water efforts of aid and disaster agencies, not full-on replacements, but before big players like the Red Cross or U.N. consider a shift away from standard operating procedure, they need to see tests and results. That's why Eastman and HTI performed this recent field test.

White admits there's a long way to go, and a lot more testing to demonstrate this can work on a mass scale beyond the one village test in Kenya if aid agencies are going to to get on board in a big way. The HyrdoPack is still a boutique product right now, he says. "Obviously, a boutique product is not going to work in a disaster situation. It has to be more of a commodity" to work, he admits.

But in Mudimbia, Kenya, many people in the 90 households who got HyrdoPacks gained weight compared to their peers because of the nutrient supplements in the packs, demonstrating another possible advantage over bottled water. The packs were also able to filter out e-coli and other contaminants successfully.

HTI is still working out details for deployment that sometimes derail well-intentioned ideas like this: details like creating packaging that allows these packs to be used by anyone, of any literacy level, in any language.

So, these aren't ready to be airlifted into Japan—or the next Haiti— These aren't being widely used by relief agencies as standard practice for disasters yet, but a few thousand were deployed in Haiti and HTI is still performing further tests to fine tune the packaging design and instructions for wider use. And if that catches on, HTI estimates the relief provided by 15 helicopter loads of bottled water could be provided with just one load of HydroPacks. That's motivation for getting the product ready for deployment.

[UPDATE: HTI tells GOOD that Hearts and Hands International is collecting donations to supply HydroPacks to the people of the Buvalangi District of Kenya before the next flooding season if you want to contribute.]

If you are totally ready to move on from Donald Trump, you're not alone. According to a report last April from the Wason Center National Survey of 2020 Voters, "President Trump will be the least popular president to run for reelection in the history of polling."

Yes, you read that right, "history of polling."

After three years on the sidelines, Colin Kapernick will be working out for multiple NFL teams on Saturday, November 16 at the Atlanta Falcons facility.

The former 49er quarterback who inflamed the culture wars by peacefully protesting against social injustice during the national anthem made the announcement on Twitter Tuesday.

Kaepernick is scheduled for a 15-minute on-field workout and an interview that will be recorded and sent to all 32 teams. The Miami Dolphins, Dallas Cowboys, and Detroit Lions are expected to have representatives in attendance.

"We like our quarterback situation right now," Miami head coach, Brian Flores said. "We're going to do our due diligence."

NFL Insider Steve Wyche believes that the workout is the NFL's response to multiple teams inquiring about the 32-year-old quarterback. A league-wide workout would help to mitigate any potential political backlash that any one team may face for making an overture to the controversial figure.

Kapernick is an unrestricted free agent (UFA) so any team could have reached out to him. But it's believed that the interested teams are considering him for next season.

Earlier this year, Kaepernick and Carolina Panthers safety Eric Reid reached a financial settlement with the league in a joint collusion complaint. The players alleged that the league conspired to keep them out after they began kneeling during the national anthem in 2016.

Before the 2019 season, Kaepernick posted a video of himself working out on twitter to show he was in great physical condition and ready to play.

Kaepnick took the 49ers to the Super Bowl in 2012 and the NFC Championship game in 2013.

He has the 23rd-highest career passer rating in NFL history, the second-best interception rate, and the ninth-most rushing yards per game of any quarterback ever. In 2016, his career to a sharp dive and he won only of 11 games as a starter.


In the category of "claims to fame nobody wants," the United States can now add "exporter of white supremacist ideology" to its repertoire. Super.

Russell Travers, acting director of the National Counterterrorism Center, made this claim in a briefing at The Washington Institute in Washington, D.C. "For almost two decades, the United States has pointed abroad at countries who are exporters of extreme Islamist ideology," Travers said. "We are now being seen as the exporter of white supremacist ideology. That's a reality with which we are going to have to deal."

Between Alexa, Siri, and Google, artificial intelligence is quickly changing us and the way we live. We no longer have to get up to turn on the lights or set the thermostat, we can find the fastest route to work with a click, and, most importantly, tag our friends in pictures. But interacting with the world isn't the only thing AI is making easier – now we can use it save the world, too.
