The Polluting Paper Mill That Helped Inspire the First Earth Day

Tuesday, April 22, 2025

Every day drivers head north on Route 205 out of Portland, Oregon, cross the mighty Columbia River and the state line, and arrive in Washington. Many of them will immediately head east, where on a clear day they’ll soon see snow-capped Mt. Hood looming over Highway 14. Also known as the Lewis & Clark Highway, this busy road will take them toward the suburban cities of Camas and Washougal. But as they arrive in Camas and cross a narrow bridge, something else will loom over the scenic view: an enormous paper mill on the river’s edge. That paper mill, which at one point processed hundreds of tons a day, has been a defining element of Camas for more than a century. The town grew up around it. Residents walked down the hill to work there and sent their kids up the hill to go to school, where the local basketball team is still called the Papermakers (complete with a mascot, the Mean Machine, that looks like an anthropomorphic paper press).

Much of the 660-acre property lies fallow. But its legacy lives on — in the history and pride of Camas, in the minds of its residents, and in the soil and water, which many people worry carry the burden of generations of pollution. And although few realize it, the paper mill’s legacy also exists on the national stage. In many ways it inspired the first Earth Day. Famed environmental advocate Denis Hayes coordinated the first national Earth Day in 1970. He later founded the Earth Day Network and became a leader in solar power and energy policy. But before that he grew up in Camas, which at the time had an occasionally noxious reputation. “If you talked to someone in Portland and mentioned Camas, universally the response was, ‘Oh yeah, that’s where the stink comes from,’ ” Hayes, now 80, recalled during a recent Zoom presentation to an in-person audience at the Camas Public Library. “The whole region was known for the stink of this uncontrolled paper mill.” The stink came from “vast quantities of uncontrolled sulfur dioxide and hydrogen sulfide” emitted by the mill. Those pollutants came back down in the form of acid rain — and as Hayes noted, it rains quite a bit in the Pacific Northwest. Hayes speaking to Camas residents over Zoom. Photo: John R. Platt/The Revelator The effect was immediately visible in town, where the roofs of cars corroded under the acidic onslaught. “People began to ask, well, if it’s doing that to my car, what’s it doing to me,” Hayes said. “The answer, with regards to the automobiles, was that instead of reducing the pollution, they put a shower at the end of the parking lot” to rinse cars before they drove home. Wildlife was affected, too. “Every now and then you’d go down to the Columbia River slough and find scores of dead fish, in some cases hundreds of dead fish, just floating there,” Hayes said. Camas had its good sides, of course. “What I did have growing up was the ability to walk through some of the most magnificent forests on Earth and to ride my bicycle down through the Columbia River Gorge and the spectacular scenery,” Hayes recalled. But even there the paper mill took a toll. “You’d go out in the forest and go hiking in the summer, in these astonishingly beautiful Douglas fir forests, and then two years later you go back there and it is almost clearcut. There was this catastrophic approach to clearing out natural resources.” The beauty and the destruction “came together and sort of made me think, not too profoundly, that it must be possible to make paper without destroying the planet,” he said. Camas was just one of Hayes’ influences, and Hayes was one of many people behind the first Earth Day and the environmental successes that followed. But what followed remains significant. “The context then was one where we were pretty highly motivated to try to get some kinds of regulations someplace,” Hayes recalled. “This is not a personal accomplishment. There were a huge number of things that were involved in this, including the presidential aspirations of a senator named Ed Muskie.” Posters about Hayes and the first Earth Day at Camas Public Library.

And we managed to take out seven of 12. And it was clear that we were the margin of a victory in each of those cases.” Among the defeated politicians was Rep. George Fallon. “At that time Fallon was the chairman of the House Public Works Committee. If you wanted to have a federal building, you wanted to have a prison, a courthouse, a dam, any kind of public work in your district anywhere across the country, you had to have the permission of the guy who chaired that committee. When we took out George Fallon, clearly with an environmental campaign, that absolutely transformed the House of Representatives.” One month after that election, Muskie helped introduce what would become the Clean Air Act. “And the Clean Air Act passed the Senate on a voice vote and passed the House of Representatives 434 to 1. There was one member of both Houses of the American Congress that voted against the Clean Air Act. Something that would have been inconceivable in 1969 became unstoppable in 1970,” Hayes said. “Those are the kinds of magic moments that can happen in a democracy where everything, just like a school of fish is going in this direction and suddenly it goes in a different direction,” he continued. “It was my thrill to have been part of a handful of those occasions.” A new generation of Camas residents — in fact, multiple generations — has taken the lesson of the first Earth Day to heart.

Hundreds of people plunged into the Chicago River’s chilly waters on Sunday as part of the first organized swim in the river for nearly 100 years, a previously unthinkable act in what was once one of the most befouled waterways in the world.About 300 people, some wearing wetsuits, jumped into the Chicago River for a mile-long looping swim on an early, overcast midwest morning, a feat made possible by the often unseen but crucial progress the US has made in the past half century in cleaning its rivers of toxic pollution.“It’s overwhelming to see this happen, it’s unbelievable to see swimmers swim past us now,” said Doug McConnell, the main organizer of the event.McConnell, a Chicago area native and co-founder of A Long Swim, had been pushing the city’s leadership for more than a decade to allow a swim in the river, the first such event since 1927, having witnessed the blossoming urban river swimming movement take hold in cities such as Paris, Munich and Amsterdam.“Seeing that really planted a seed, and we are thrilled we are finally doing this and that it has got global attention – we had applications across the US and 13 countries,” said McConnell, who hopes this will become an annual event and spread to other US cities.McConnell didn’t leap into the water on Sunday but is an accomplished long-distance swimmer, having traversed the English Channel, which he recalls as “14 hours of getting slapped around”, and swam around the island of Manhattan, all in aid of amyotrophic lateral sclerosis (ALS) fundraising.“I think the water conditions will surprise people because it will be cleaner than they expect,” he said. “The psychology of so many Chicagoans was that the river is untouchable – this isn’t true and we are proving this today.“My grandfather grew up in Chicago and I think what his reaction to all of this would be because the river had an absolutely toxic reputation then. It was repulsive, absolutely untouchable.”The Chicago River has a long history of being meddled with. Each year it is dyed green for St Patrick’s Day and, infamously, in 2004 the tour bus of Dave Matthews Band released 800lbs (363kg) of human waste through a bridge grate that landed on top of a boat of mightily unfortunate sightseers traveling on the river.Indeed, Chicago initially grew by treating its slow-moving river as an unfettered dumping area. Sewage and other waste was routinely funneled into the river, including carcasses and effluent from huge slaughterhouses that clustered beside the waterway – to the extent that a section of the river is still called “bubble creek” due to the gas given off by the rotting sludge on the riverbed.The river became so foul, causing deadly outbreaks of cholera and typhoid, that the city took the extraordinary step in 1900 of reversing the river’s flow by creating a system of canals and locks, to avoid Chicago’s source of drinking water in Lake Michigan becoming poisoned. Today, the 156-mile (265km) river meanders from Lake Michigan through Chicago so its water ultimately empties into the Gulf of Mexico.“We treated the river like it was part of the sewer system, which haunted us,” said Margaret Frisbie, the executive director of Friends of the Chicago River. Riverside buildings typically didn’t even have windows overlooking what was known as “the stinking river”, with the ribbon of water shunned as part of Chicago’s civic fabric.“Until just a few years ago people would’ve thought it would be outrageous to jump into it,” Frisbie said. When Friends of the Chicago River formed in 1979 with a vision to restore the ecological function of a river that could be enjoyed by people and wildlife alike, “people thought we were crazy,” she said.Yet the 1970s was a seminal decade for environmental protection in the US, with the passage of the Clean Water Act and the creation of the Environmental Protection Agency (EPA) – bringing new restrictions on pollution dumped into rivers, streams and lakes. Where once American rivers were so toxic they could catch fire, a new era had begun that would allow US cities to think more affectionately of their foundational waterways.In Chicago, the slaughterhouses shut down, new sewage and storm water infrastructure was built and teams of volunteers, as they do to this day, toiled to clean up trash.Dozens of species of fish returned, as did beavers and snapping turtles such as Chonkosaurus, an enormous, locally famous specimen sometimes seen lounging by the river.In 2016, a riverside public pathway was completed to knit the downtown area to its adjacent water, allowing Chicagoans in new bars and restaurants to gaze upon a river that is no longer a fetid soup, a place clean enough that people can now swim in it. On 12 September, it was announced that Friends of the Chicago River won an international prize in recognition of the river’s transformation.“So many people are on rental boats on the river these days – it’s heaving with people,” Frisbie said. “People want to work near the river, live near it, be on it. It’s remarkable to see people have that connection with it again.“This swim is emblematic of all the work we’ve done over the past 50 years to improve our rivers. It shows you can change the destiny of any natural resource and do some good. It feels that’s something we need right now.”America’s rivers may now increasingly be places of scenic recreation rather than industrial sacrifice zones, but this does depend on the vicissitudes of politics. The Trump administration is narrowing the application of the Clean Water Act, which helped ensure healthier rivers, and is similarly weakening rules on what coal plants and factories can dump in waterways. The bad old days may be a thing of the past, but ongoing progress isn’t guaranteed.“If the federal government retreats from enforcement, things could slide backwards,” Frisbie said. “It’s incumbent on cities, countries and states to be vigilant. Our river is beloved now – people want to use it, wildlife needs it, we need it. We want to maintain that rather than see it roll back.”On Sunday, though, few swimmers were mulling such weighty topics as they lined up in robes, serenaded by the skirl of the Chicago police department’s bagpipes and drum, before stripping and vaulting into the river, bobbling flotation devices tethered to their waists.Organizers had zealously tested the water in the weeks before the event, finding that the river was consistently safe in terms of EPA standards on fecal coliform – essentially, poo in the water. The river was scanned, too, for any potential obstructions to the swimmers.Among the participants for the first river swim in 98 years – all strictly vetted to ensure they could complete the course – was Olivia Smoliga, who grew up in the Chicago suburbs and went on to win a gold medal in backstroke at the 2016 Olympic games.Open water swimming is a different beast to the lanes of a pool, but Smoliga’s competitive spirit compelled her to speed around the river loop, even though it was not intended to be a race.“You have people throwing elbows there – you have to watch out for fingernail length, everything,” she said. “The fact they were able to clean up the river and do such great work, to have this full on race happen, is trippy. But it’s really cool.”

Why Is a Floating Seaweed Taking Over an Entire Ocean? Researchers Have the Answer

Sargassum expansion across the Atlantic is tied to nutrient pollution and ocean circulation. Its growth now affects ecosystems and coastal communities.

Researchers at Florida Atlantic University’s Harbor Branch Oceanographic Institute have compiled a comprehensive review covering forty years of data on pelagic sargassum, the free-floating brown algae that plays a crucial role in the Atlantic Ocean. For decades, scientists believed sargassum was largely restricted to the nutrient-poor waters of the Sargasso Sea. It is now clear that this seaweed has become a widespread and fast-growing presence across the Atlantic, with its expansion tied to both natural variability and human-driven nutrient inputs. Published in the journal Harmful Algae, the review examines the emergence and persistence of the Great Atlantic Sargassum Belt, an enormous seasonal bloom that spans from West Africa to the Gulf of Mexico. Since first being observed in 2011, this belt has formed nearly every year—except in 2013—and in May reached a record biomass of 37.5 million tons. This figure excludes the long-term background biomass of 7.3 million tons typically found in the Sargasso Sea. Linking nutrient enrichment to sargassum expansion The analysis integrates historical oceanographic records, modern satellite data, and detailed biogeochemical studies to better explain shifts in sargassum abundance, distribution, and nutrient balance. The findings emphasize the influence of human-driven nutrient loading on ocean processes and the urgent need for international collaboration to track and mitigate the impacts of these vast seaweed blooms. “Our review takes a deep dive into the changing story of sargassum – how it’s growing, what’s fueling that growth, and why we’re seeing such a dramatic increase in biomass across the North Atlantic,” said Brian Lapointe, Ph.D., lead author and a research professor at FAU Harbor Branch. “By examining shifts in its nutrient composition – particularly nitrogen, phosphorus and carbon – and how those elements vary over time and space, we’re beginning to understand the larger environmental forces at play.” Sargassum on a beach in Palm Beach County in 2021. Credit: Brian Lapointe, FAU Harbor BranchAt the start of the review, Brian Lapointe and his colleagues, Deanna F. Webber, research coordinator, and Rachel Brewton, Ph.D., assistant research professor at FAU Harbor Branch, note that early oceanographers mapped the Sargasso Sea by tracking surface patches of sargassum. They assumed the seaweed flourished in its warm, clear, yet nutrient-poor waters. This idea later presented a paradox, as mid-20th-century researchers went on to describe the same region as a “biological desert.” Resolving the paradox with modern studies However, recent satellite observations, ocean circulation models, and field studies have resolved this paradox by tracing the seasonal transport of sargassum from nutrient-rich coastal areas, particularly the western Gulf of America, to the open ocean via the Loop Current and Gulf Stream. These findings support early theories by explorers who proposed that Gulf-originating sargassum could feed populations in the Sargasso Sea. Remote sensing technology played a pivotal role in these discoveries. In 2004 and 2005, satellites captured extensive sargassum windrows – long, narrow lines or bands of floating sargassum – in the western Gulf of America, a region experiencing increased nutrient loads from river systems such as the Mississippi and Atchafalaya. “These nutrient-rich waters fueled high biomass events along the Gulf Coast, resulting in mass strandings, costly beach cleanups, and even the emergency shutdown of a Florida nuclear power plant in 1991,” Lapointe said. “A major focus of our review is the elemental composition of sargassum tissue and how it has changed over time.” Growth rates and limiting nutrients Laboratory experiments and field research dating back to the 1980s confirmed that sargassum grows more quickly and is more productive in nutrient-enriched neritic waters than in the oligotrophic waters of the open ocean. Controlled studies revealed that the two primary species, sargassum natans and sargassum fluitans, can double their biomass in just 11 days under optimal conditions. These studies also established that phosphorus is often the primary limiting nutrient for growth, although nitrogen also plays a critical role. From the 1980s to the 2020s, the nitrogen content of sargassum increased by more than 50%, while phosphorus content decreased slightly, leading to a sharp rise in the nitrogen-to-phosphorus (N:P) ratio. VIDEOThe story of sargassum over four decades. Credit: Brian Lapointe, FAU Harbor Branch “These changes reflect a shift away from natural oceanic nutrient sources like upwelling and vertical mixing, and toward land-based inputs such as agricultural runoff, wastewater discharge, and atmospheric deposition,” said Lapointe. “Carbon levels in sargassum also rose, contributing to changes in overall stoichiometry and further highlighting the impact of external nutrient loading on marine primary producers.” The review also explores how nutrient recycling within sargassum windrows, including excretion by associated marine organisms and microbial breakdown of organic matter, can sustain growth in nutrient-poor environments. This micro-scale recycling is critical in maintaining sargassum populations in parts of the ocean that would otherwise not support high levels of productivity. Influence of Amazon River outflow Data from sargassum collected near the Amazon River mouth support the hypothesis that nutrient outflows from this major river contribute significantly to the development of the GASB. Variations in sargassum biomass have been linked to flood and drought cycles in the Amazon basin, further connecting land-based nutrient inputs to the open ocean. The formation of the GASB appears to have been seeded by an extreme atmospheric event – the negative phase of the North Atlantic Oscillation in 2009 to 2010, which may have helped shift surface waters and sargassum from the Sargasso Sea southward into the tropical Atlantic. However, the researchers caution that there is no direct evidence of this movement. Moreover, genetic and morphological data suggest that some sargassum populations, particularly the dominant S. natans var. wingei, were already present in the tropical Atlantic prior to 2011, indicating that this region may have had an overlooked role in the early development of the GASB. “The expansion of sargassum isn’t just an ecological curiosity – it has real impacts on coastal communities. The massive blooms can clog beaches, affect fisheries and tourism, and pose health risks,” said Lapointe. “Understanding why sargassum is growing so much is crucial for managing these impacts. Our review helps to connect the dots between land-based nutrient pollution, ocean circulation, and the unprecedented expansion of sargassum across an entire ocean basin.” Reference: “Productivity, growth, and biogeochemistry of pelagic Sargassum in a changing world” by Brian E.
