Imagine you’re going fishing with your grandmother. The river glitters in the sunlight, the water looks clean, and your grandmother says her mother also fished here. You catch fish, bring it home, and make soup. Everything is just like always. Only no one told you that this fish shouldn’t be eaten. That poison is hidden in it. And that the warning about it was written only in English — a language your grandmother doesn’t know.
That’s exactly what happened to hundreds of families along the Duwamish River in Seattle. And this isn’t just a story about a dirty river. It’s a story about how injustice can live for a very long time. Sometimes—up to eighty years.
What the Duwamish Is and Why It’s Sick
The Duwamish River flows through the southern part of Seattle and empties into Puget Sound. Long ago, it was a beautiful, winding river where salmon ran. The Duwamish people, an Indigenous community, lived here for thousands of years and called the river home—indeed, their name is what gave the river its name.
But in the twentieth century, everything changed. Along the banks, factories, shipyards, and warehouses were built. Into the river, for decades, went oil, chemicals, and heavy metals. By 2001, the U.S. government officially recognized the Duwamish as one of the most contaminated places in the country—a so-called “Superfund site.” This means the river is so ill that treating it will cost hundreds of millions of dollars and will take many years.
There is fish in the river. They swim, and they look normal. But inside them are stored-up poisons called PCBs (polychlorinated biphenyls). Eating that fish often can make people seriously ill. It’s especially dangerous for children and pregnant women.
Families Who Didn’t Know
Who lives near the Duwamish today? Mostly immigrant families. Vietnamese people who came to Seattle after the war. Latino families. People from Somalia and Ethiopia. Folks who do hard, physical jobs, live modestly, and really value the chance to catch fish themselves—because it’s cheaper, tastier, and a reminder of home.
For many of them, fishing isn’t just food. It’s tradition. It’s a way to pass something important on to their children. A grandfather teaches his grandchild how to hold a fishing rod. A grandmother cooks fish soup using a recipe she brought from another country.
But for years, warnings that it was dangerous to eat fish from the Duwamish were posted only in English. Or they were translated—but so poorly that people still didn’t understand how serious it was. Researchers from the University of Washington found that some families ate fish from the river several times a week—hundreds of times more than the “safe” level scientists had calculated.
“We didn’t know. Nobody came to us and explained. We just lived next to the river,” one neighborhood resident, a Vietnamese woman who moved to Seattle in the 1980s, said.
An Old Injustice That Created a New One
Here is the most surprising part of the story. Where did this contamination come from? Why were so many factories located right here, near homes of poor families?
To understand that, you have to go back to 1942.
Before World War II, the Duwamish River valley was an agricultural area. Japanese American families lived here—people who came from Japan or were born in America but kept Japanese roots. They grew vegetables, ran farms, and knew every patch of that land.
But in February 1942, U.S. President Franklin Roosevelt signed an order requiring that all people of Japanese ancestry on the West Coast be relocated to special camps. This was called “internment.” In just a few weeks, thousands of families lost everything: homes, farms, businesses, property. They were sent behind barbed wire only because they looked like enemies—even though most were American citizens and had committed no crimes.
When Japanese American farmers left—actually, when they were forcibly removed—their land was taken over by industrial businesses. Factories, shipyards, chemical storage warehouses. And it was those operations that poisoned the river for decades to come.
So you get this astonishing and heartbreaking chain: some people were driven out unfairly → factories moved in → the factories poisoned the river → other people, too—immigrants as well, vulnerable as well, not knowing the language—ended up next to a poisoned river, and nobody made sure they were warned.
A Struggle That Continues
But the story doesn’t end with injustice. It ends— or, more accurately, it continues—with a fight.
An organization called the Duwamish Coalition brought together exactly those immigrant communities that lived alongside the river. Vietnamese, Latino, and African families began demanding: translate the warnings into our languages. Explain to us what’s happening. Include us in discussions about cleaning up the river.
And it worked. Step by step, warnings started appearing in Vietnamese, Spanish, and Somali. Volunteers began going right to the river’s edge and talking with fishermen personally. Scientists started working with communities, not just publishing reports that nobody read.
Cleaning up the Duwamish is a massive, expensive project that will take many more years. But even now, the river is a little cleaner. And most importantly, the voices of people who used to be invisible can now be heard.
This river story is actually about something bigger. About how injustice rarely happens only once. It’s like ripples in water: one wave creates the next. Japanese farmers were driven out—factories appeared. Factories poisoned the river—new families were affected. But justice works the same way, too: one brave step creates another. One family that wasn’t afraid to say, “We’re here, we exist—translate warnings for us,” opened the way for hundreds of others.
The Duwamish River remembers everything. And the people who live beside it do not forget either.
