A Century of Poison
in Seattle’s River
For over 100 years, Boeing and more than 100 corporations dumped PCBs, arsenic, dioxins, and carcinogens into the Lower Duwamish Waterway, the working river at the heart of Seattle. Now the U.S. Department of Justice and Washington State are suing to force a cleanup they have resisted for decades.
● Critical Severity
TL;DR
Since the early 1900s, Boeing, Ford Motor Company, BNSF Railway, Puget Sound Energy, and more than 100 other corporations have used the Lower Duwamish Waterway in Seattle as an industrial dump, releasing PCBs, arsenic, dioxins, and carcinogenic compounds into a waterway that communities, fish, and wildlife depend on. The contamination is so severe that EPA placed the site on the federal Superfund National Priorities List in 2001, and in 2014 issued a formal cleanup order that major polluters have continued to resist. On March 4, 2026, the U.S. Department of Justice and Washington State filed a federal lawsuit to force those corporations to pay for cleanup costs and to actually perform the required remediation. These corporations poisoned a river, fought cleanup for decades, and let a working-class waterway community bear the costs of their contamination. That is not a policy disagreement: it is environmental violence.
Demand full remediation and criminal accountability for executives who allowed this to continue for over a century.

Regulatory Failures
How oversight broke down · 5 points
▾
| 01 | Despite decades of industrial contamination, EPA only placed the Lower Duwamish Waterway on the Superfund National Priorities List in September 2001, more than a century after polluting industries began operating along the waterway. | high |
| 02 | The remedial investigation began in 2000 and was not completed until 2010; the feasibility study ran until 2012. Major polluters had a 12-year window between the site’s listing and the issuance of a formal cleanup decision in 2014. | high |
| 03 | Even after EPA issued a Record of Decision mandating cleanup in November 2014, corporations did not begin remediation voluntarily. It took EPA until July 2024 to issue a Unilateral Administrative Order requiring Boeing, the City of Seattle, and King County to act. | high |
| 04 | Filing of the federal lawsuit did not occur until March 2026, a full 12 years after the cleanup decision and 25 years after the Superfund listing, illustrating how regulatory timelines create structural advantages for corporations that delay accountability. | med |
| 05 | Washington State’s Model Toxics Control Act, enacted in 1989 after a citizens’ initiative, explicitly recognizes that every person has a fundamental right to a healthy environment. That law has existed for over 35 years while contamination persisted and enforcement lagged. | med |
Public Health and Safety
Toxic contamination and its human cost · 5 points
▾
| 01 | PCBs, the most significant human health risk driver at the site, are classified as probable human carcinogens and accumulate in the body’s fatty tissue. Duwamish community members who eat fish from the river face elevated lifetime cancer risk. | high |
| 02 | Arsenic at the site is a known human carcinogen linked to bladder, lung, and skin cancers. Its documented presence at the site as a significant risk driver means the surrounding community has been chronically exposed to a substance that causes cancer. | high |
| 03 | Dioxins and furans, byproducts of combustion and chemical manufacturing, are among the most toxic compounds ever measured. EPA identified them as significant human health risk drivers at the Duwamish site, alongside carcinogenic PAHs. | high |
| 04 | EPA has formally determined that hazardous substances at the site present significant risks to human health and the environment, and that response actions are necessary to abate an imminent and substantial endangerment to the public health. | high |
| 05 | Ongoing stormwater and sewage discharges into the waterway continue to deposit contaminants even as cleanup is litigated. The pollution is not a historical artifact: it is an active, ongoing public health emergency. | high |
Community Impact
Who bears the cost · 4 points
▾
| 01 | The Lower Duwamish Waterway has served as Seattle’s major industrial corridor since the early 1900s. The communities living and working along it, disproportionately low-income and communities of color, have borne the health consequences of that century of industry. | high |
| 02 | The contaminated waterway stretches five miles through Seattle and into Tukwila, affecting a significant urban corridor. Slips, inlets, bays, and banks connected to the waterway are all part of the affected site. | med |
| 03 | The river serves as habitat for salmon and other fish species culturally and economically vital to Indigenous communities in the region. Contamination disrupts not only public health but Indigenous food sovereignty and treaty rights tied to the waterway. | high |

Corporate Accountability Failures
Weak penalties, delayed justice · 4 points
▾
| 01 | Despite the site being listed on Superfund in 2001 and a cleanup decision issued in 2014, no major corporation has been compelled to complete remediation. The 2026 lawsuit represents the first significant attempt at court-ordered enforcement. | high |
| 02 | The complaint does not name any individual executives as defendants. Corporations face civil liability for cleanup costs, but no criminal charges or personal financial liability for the decision-makers who authorized decades of contamination. | high |
| 03 | CERCLA’s strict joint and several liability standard means each defendant is liable for all cleanup costs regardless of their individual contribution. In practice, however, wealthier corporations frequently use legal proceedings to delay payment and shift costs onto smaller defendants or the public. | med |
| 04 | The City of Seattle and King County are named as defendants alongside Boeing and private corporations, meaning public institutions that failed to prevent contamination are also legally liable, further complicating cleanup and raising questions about who ultimately bears the financial burden. | med |
Exploiting Delay
How years become decades · 4 points
▾
| 01 | From the first administrative consent order in 2000 to the federal lawsuit filed in March 2026 spans 26 years. During that period, contaminated sediment remained in the waterway and community members continued to be exposed. | high |
| 02 | The remedial investigation alone took a decade to complete, from 2000 to 2010. Every year of investigation is a year corporations avoided paying for cleanup, while the government, funded by taxpayers, bore the cost of study and enforcement. | high |

💬 Direct Quotes from the Legal Record
QUOTE 1
The right to a healthy environment
Community Impact
“MTCA evolved from a Washington State citizens’ initiative and became law in 1989. It is based on the understanding that each person has a fundamental, inalienable right to a healthy environment, and that the present generation has an obligation to preserve the State’s land, air, and waters for the benefit of future generations.”
💡 This is the legal standard Washington State set in 1989. Over 100 corporations violated it for decades. The law existed; enforcement did not.
QUOTE 2
41 hazardous substances confirmed
Core Allegations
“EPA has documented the presence of 41 hazardous substances within the Site that pose significant risks to human health and/or the environment. The most significant human health risk drivers include polychlorinated biphenyls (PCBs), arsenic, carcinogenic polycyclic aromatic hydrocarbons (cPAHs), dioxins, and furans.”
💡 Forty-one separate toxic substances in a single waterway. Each one is the direct result of corporate decisions to dispose of waste cheaply rather than responsibly.
QUOTE 3
Imminent and substantial endangerment
Public Health and Safety
“The President, through his delegate, has determined that there may be an imminent and substantial endangerment to the public health or welfare or the environment because of a release of hazardous substances or a threatened release of hazardous substances at or from the Site.”
💡 “Imminent and substantial endangerment” is the federal government’s threshold for emergency environmental action. The community has lived under that threshold for over 100 years.
QUOTE 4
Active ongoing discharges
Core Allegations
“Combined sewage and stormwater systems and stormwater management systems within the Site have discharged and continue to discharge untreated collected wastewaters and stormwaters into the Waterway.”
💡 The word “continue” is critical. This is not only historical contamination. Pollutants are flowing into the Duwamish right now, while litigation proceeds.
QUOTE 5
Strict, joint and several liability
Corporate Accountability Failures
“Each person who is liable under this section is strictly liable, jointly and severally, for all remedial action costs . . . resulting from the releases or threatened releases of hazardous substances.”
💡 The law is unambiguous. Each defendant owes the full cost of cleanup. The question is not whether liability exists; it is how long corporations will use the legal system to avoid paying it.
QUOTE 6
Over a century as an industrial dump
Community Impact
“The Site has served as Seattle’s major industrial corridor since the early 1900s. Ongoing and past industrial, urban, and transportation activity has resulted in significant contamination of the Waterway and many nearby properties.”
💡 “Major industrial corridor” is the legal document’s neutral language. The reality is that for over 100 years, corporations treated a living waterway as a free dump at public and community expense.
💬 Commentary
What Exactly Did These Corporations Do to the Duwamish River?
▾
Over more than a century of industrial activity, Boeing and over 100 other corporations released PCBs, arsenic, dioxins, furans, and carcinogenic compounds into the Lower Duwamish Waterway through their manufacturing, disposal, and transportation operations. Combined with untreated sewage and stormwater discharges that continue today, these companies turned a living waterway into one of the most contaminated Superfund sites in the Pacific Northwest. EPA has confirmed 41 separate hazardous substances in the waterway. That is not an accident. It is the cumulative result of corporate decisions to treat a shared public resource as a private disposal system.
Why Did It Take Until 2026 to File This Lawsuit?
▾
The Duwamish was listed as a Superfund site in 2001, a cleanup decision was issued in 2014, and a formal administrative order went to Boeing in 2024. Yet a lawsuit compelling compliance was not filed until March 2026. This 25-year gap between Superfund listing and federal litigation is not an anomaly; it is the system functioning as designed for powerful corporate defendants. Every year of delay is a year corporations retain capital, defer expenditure, and allow contamination to persist while communities absorb the health consequences. The regulatory timeline is itself a form of environmental injustice.
Who Is Most Harmed by the Duwamish Contamination?
▾
The communities living, working, and fishing along the Lower Duwamish bear the greatest burden of this contamination. These are disproportionately low-income residents and communities of color who have had fewer resources to advocate for cleanup, fewer options to relocate, and greater reliance on the river’s fish as a food source. Indigenous communities with treaty rights tied to the Duwamish watershed face threats to both their cultural practices and their health. Meanwhile, Boeing and its co-defendants built their profits on operations that poisoned this community’s river, and have faced decades of civil process rather than urgent accountability.
Is This Lawsuit Legitimate? Could It Actually Force a Cleanup?
▾
Yes. The legal basis is solid and well-established. CERCLA (the Superfund law, enacted in 1980) imposes strict, joint, and several liability on current and past owners, operators, and anyone who arranged for disposal of hazardous substances at a contaminated site. Washington State’s Model Toxics Control Act applies the same standard under state law. The federal government and Washington State are not pursuing speculative claims; they are seeking to enforce a cleanup decision EPA issued in 2014 after years of study. The legal question is not whether defendants are liable; it is how much they will pay and how long litigation will take.
What Happens to the Communities While Litigation Drags On?
▾
They continue to be exposed. The complaint itself notes that stormwater and sewage systems “continue to discharge” untreated wastewater into the waterway. Contaminated sediment remains. Fish remain unsafe to eat in certain quantities. Families living near the river breathe air and touch soil affected by decades of industrial pollution. Justice delayed is not justice suspended; for the communities of the Duwamish valley, it is ongoing harm that compounds daily while lawyers file briefs and corporations negotiate contributions.
Why Are Boeing, Ford, and BNSF Named Alongside Over 100 Other Companies?
▾
CERCLA and MTCA cast a wide net deliberately. Anyone who owned or operated a facility at the site, disposed of hazardous substances there, or arranged for transport of hazardous waste to the site can be held strictly liable for all cleanup costs, regardless of their individual contribution. This makes it harder for the largest polluters to argue that smaller actors should bear the cost. In practice, however, major corporations like Boeing often negotiate their share of liability in separate proceedings, while smaller dissolved companies may be unable to contribute, leaving gaps that fall on the government and ultimately on taxpayers.
What Can I Do to Support Duwamish River Communities and Demand Accountability?
▾
Support organizations doing direct work on the Duwamish, including the Duwamish River Community Coalition and the Duwamish Tribal Services. Contact your U.S. Senators and House Representatives and demand full funding for EPA Superfund enforcement and cleanup programs. Urge Washington State legislators to strengthen MTCA penalties so that delay becomes financially punishing for corporations rather than profitable. Oppose any federal efforts to cut EPA enforcement budgets. Attend public comment periods on the cleanup plan. And amplify the stories of the communities most harmed by this contamination, because corporate polluters count on the public losing interest before the cleanup is complete.
Does This Connect to Broader Patterns of Corporate Environmental Wrongdoing?
▾
Absolutely. The Duwamish case follows a pattern seen at Superfund sites across the United States: corporations profit from industrial activity, externalize the environmental costs onto communities with less political power, and then use regulatory timelines and legal complexity to delay paying for the harm they caused. The same corporations that contaminated the Duwamish lobbied to weaken environmental regulations, fought cleanup orders through administrative proceedings, and continue to operate and generate profit while communities wait. This is not a failure of capitalism to regulate itself. It is capitalism functioning as intended, with environmental destruction absorbed by the public while profits remain private.
