We wanted to share information about PFAs briefly and are sharing a blog originally posted by Christina Barston (with permission) here, as she has already done a good job detailing the challenges. A reflection on the state of PFAS evidence, exposure, and the responses underway.

Why introspection in the Global South is as important as external reform in decolonizing international development.

For millions of girls, menstruation still means shame, silence, and missed opportunities. At FLUSH, we believe that menstrual hygiene management (MHM) isn’t just about products — it’s about dignity, access, climate resilience, gender equality, and sustainable systems. Two landscape assessments — in Fiji and Bangladesh — highlight just how interconnected these values are, and what we can learn as a global community working toward menstrual equity.

As MrBeast partners with WaterAid for his latest water campaign, the water and sanitation (WASH) community has had mixed reactions. Some celebrated the partnership as progress from his previous solo drilling efforts that drew heavy criticism. Others remained skeptical about celebrity involvement in complex development work. But this conversation reveals something deeper: our sector desperately needs to grapple with how we engage public attention and funding.

On July 26, 1990, the Americans with Disabilities Act (ADA) was signed into law, signaling the promise of equal access and dignity in public spaces for millions of Americans with disabilities. Thirty-five years later, the ADA remains a cornerstone of civil rights, but it’s important to examine how the law falls short and reimagine it to serve more people, more fully.

People may wonder why FLUSH has expanded into climate work. The simple truth is that water, sanitation, and climate aren't separate issues—they're deeply interconnected challenges that require integrated solutions. After seven years of helping water and sanitation professionals tell better stories with their data, we've realized that climate conversations are already happening in our work. We're just making it official.

Most people don’t think of garbage collectors as civil rights heroes. I certainly haven’t always. But that’s a problem.

Sanitation is a human right—but who decides what that really means, how it's delivered, and whose needs come first? Across Africa, critical decisions about sanitation investment, practices, and hygiene are still made in colonial languages (French, English, and Portuguese) that many people can’t fully understand. This blog looks at how language—often overlooked—shapes who gets heard and who gets left out in the WASH sector.

When visiting New York City's Tenement Museum, our Founder was drawn to a critical aspect of immigrant life that's often overlooked: sanitation. How did early urban immigrants in the US handle something as fundamental as going to the bathroom? This blog will explore some of the important history in the US, specifically, how immigrants navigated urban life.

Let’s be honest. When was the last time you got excited talking about a toilet? For decades in Tanzania, sanitation has been the wallflower at the development party. It sat quietly in the corner while water, education, and roads hogged the dance floor. Toilets? Functional. Forgettable. Often a little embarrassing.

Every drop counts - water recycling is the answer. It may sound like science fiction, but it’s not. And more importantly, it works.

People in high-income countries, like the US, often struggle to relate to the sanitation challenges in low-income countries.

Beneath the cities of Ancient Rome lay a dark, labyrinthian drain system called the Cloaca Maxima, which swept up stormwater and wastewater.

Any freeze on foreign aid is affecting thousands of people, making it harder for our friends in international development.

Last week, we joined dozens of accomplished professionals and academics in for the University of Pisa and UNESCO's Water and Gender Workshop

The projects we do to handle waste sometimes produce their own waste—or become it. What do we do with the waste of our waste treatment?

Talking about toilets is often considered inappropriate or even embarrassing for something that every human does daily.

Earlier this year, our Founder visited St. Louis, Missouri—the Gateway to the West. On this trip, we visited the Gateway Arch’s museum.

FLUSH's Founder was pleased to work with Jesse Crosson from the Second Chancer Foundation and FLUSH alumna Ruth Sylvester on a brief paper.

In May 2024, Vessel held the inaugural US WASH Convening to help unify a fractured US WASH Sector.
