U.S. Borax had some toxic contamination. Now they’re being sued by the DOJ

The Non-Financial Ledger

The harm ran deep and quite quiet for a plot of land barely bigger than a city block. The people of North Kansas City did not choose to have arsenic pumped into the ground beneath their feet. A company came, blended poison for five years, packed it onto rail cars, and left the contamination behind for the community to inherit.

The betrayal is measured in time. Missouri listed this site as an abandoned or uncontrolled hazardous waste site in 1997. The soil and groundwater were poisoned with arsenic, a substance the law itself calls a danger to public health and safety. Yet a cleanup plan was not selected until September 2022. That is a quarter century of a known toxic site sitting in a residential county while the process ground forward.

What lingers is the ordinary trust that was broken. Groundwater what runs beneath the homes and streets of Clay County, Missouri. It was contaminated, and the community carried that risk while the company that caused it moved on decades earlier. So evil!

Legal Receipts

“Defendant leased the Site between about 1963 and 1968, during which time it conducted herbicide blending operations. These operations included receiving bulk shipments of arsenic compounds, mixing and packaging the compounds, and loading rail cars with the mixed arsenic-based herbicides for distribution.”

• This is the government’s direct statement that U.S. Borax physically handled and blended arsenic compounds on the site.
• It establishes the operation ran for roughly five years, not a one-time accident.
• The reference to loading rail cars shows this was an industrial-scale distribution hub for arsenic-based poison.

“As a result of Defendant’s operations, the soils and groundwater at the Site became contaminated with arsenic, 2,4-dichlorophenoxyacetic acid (“2,4-D”), 2,4,5-trichlorophenoxyacetic acid (“2,4,5-T”), and pentachlorophenol (“PCP”).”

• The complaint ties the contamination directly to the company’s operations, not to some unknown third party.
• It names four separate hazardous substances found in both soil and groundwater.
• Contaminated groundwater indicates the poison migrated beyond the surface, spreading the risk.

“[A]ny person having control over a hazardous substance shall be strictly liable to the state of Missouri for the reasonable cleanup costs incurred by the state as a result of the failure of such person to clean up a hazardous substance…”

• This is Missouri’s Spill Bill, Section 260.530.1, which imposes strict liability. The state does not have to prove intent or negligence.
• It anchors the state’s separate claim to recover its own cleanup costs on top of the federal claim.
• The word “failure” frames the harm as an obligation the party in control never fulfilled.

The Poison Ledger: What Was Left Behind

A single 1.8-acre site was left contaminated with four federally designated hazardous substances. Each was named in the complaint as a direct result of the company’s blending operations.

The Decades-Long Delay: Time as a Corporate Advantage

The contamination began in the 1960s. Meaningful accountability did not arrive until 2026. The gap between the harm and the response is the story of this site.

• The company’s operations ended around 1968, yet Missouri did not list the site on its registry of abandoned or uncontrolled hazardous waste sites until 1997.
• The EPA did not place the site on the National Priorities List until 1999, more than three decades after the contamination began.
• A “Record of Decision” selecting even an interim cleanup remedy for the soil and groundwater was not issued until September 2022.
• The cost-recovery lawsuit against the company was not filed until June 5, 2026, roughly 58 years after operations ceased.

The Contractor Shield: A Delaware Shell and a Missouri Mess

The complaint documents a familiar structure: the polluting entity is a corporation organized far from the harm it caused, with a service address in a state known for shielding corporate identity.

• The defendant is incorporated under the laws of Delaware, with a designated service address in Wilmington, Delaware, hundreds of miles from the contaminated site in Missouri.
• The company was only an operator of the site, and only from 1963 to 1968, leasing rather than owning the land where it blended arsenic-based herbicides.
• By operating on leased land, the physical liability for the poisoned soil and groundwater was left behind while the operating entity moved on.
• The government is invoking CERCLA’s operator liability specifically to reach past this structure and hold the company responsible for costs incurred decades later.

Societal Impact Mapping

Public Health

The contaminants named in the complaint are not nuisances; they are substances the law itself defines as dangers to public health.

• Arsenic, a known carcinogen and acute poison, contaminated both the soil and the groundwater at the site.
• Missouri’s own statute defines arsenic as a hazardous substance that “presents a danger to the public health or safety or the environment.”
• The presence of 2,4,5-T is notable because it belongs to the same chemical family as the defoliant later condemned as Agent Orange.
• Contamination of groundwater means the poison entered the water system beneath a residential county, extending exposure risk beyond the fence line.

Environmental Degradation

The complaint documents direct, sustained contamination of the natural environment traceable to the company’s operations.

• Soils at the 1.8-acre site were contaminated with four hazardous substances as a direct result of the blending operations.
• Groundwater at the site was contaminated, indicating the pollutants migrated below the surface rather than staying contained.
• The severity was significant enough for the EPA to place the site on the National Priorities List in 1999, the federal register of the nation’s most contaminated sites.
• The environmental damage required a formal interim remedy for both soil and groundwater, selected by the EPA in September 2022.

Who Pays? Following the Cost

For nearly six decades, the public bore the cost of this contamination. The EPA and the State of Missouri paid to investigate and begin remediating a mess they did not create, and are only now seeking to recover it.

• The complaint states plainly that “EPA has conducted response actions and incurred costs regarding the Site,” meaning federal taxpayers funded the response upfront.
• Missouri incurred its own separate cleanup costs, which it is seeking to recover under the state Spill Bill.
• The company that blended the arsenic-based herbicides carried none of these costs during the decades the site sat listed and contaminated.
• Only through this June 2026 lawsuit does the government attempt to shift the financial burden back onto the party that caused the harm.

“The United States has incurred costs of response… to respond to the releases or threatened releases of hazardous substances at the Site.”

This Is the System Working as Intended

The structure of this case shows how long a corporation can hold contamination at arm’s length before the public system catches up.

• The operating window was 1963 to 1968, yet the first formal state listing did not come until 1997, a gap of roughly three decades during which no documented accountability attached.
• Federal taxpayers funded EPA response actions and remediation upfront, with cost recovery treated as a matter to be pursued afterward rather than a barrier to pollution.
• The polluting entity operated as a Delaware corporation on leased Missouri land, a structure that separated the operator from lasting responsibility for the physical site.
• CERCLA’s cost-recovery mechanism, invoked here in 2026, exists precisely because the ordinary system left decades-old industrial poison for the public to absorb.

What a Legitimate Fix Looks Like

The core failure this case exposes is a system that lets industrial contamination sit for generations before the party responsible is asked to pay. The following is editorial analysis, not a finding of the source document.

Regulatory Track

• Compress the timeline between a site’s registry listing and remedy selection; a gap of 25 years from Missouri’s 1997 listing to the 2022 Record of Decision is a failure of pace, not process.
• Require the EPA to pursue cost recovery from identified operators far earlier, rather than fronting response costs for decades before filing.
• Mandate that industrial operators of hazardous-substance sites post financial assurance for future cleanup as a general environmental standard, so the public is not left funding remediation.

Legislative Track

• Strengthen strict-liability frameworks like Missouri’s Spill Bill (Section 260.530) so that operator liability cannot be diluted by corporate relocation or dissolution over time.
• Close the practical gap that allows out-of-state incorporation to slow accountability for in-state environmental harm.
• Fund and staff state and federal cleanup programs so identified sites move from listing to remediation on a fixed statutory clock.

Corporate Governance Track

• Require companies handling designated hazardous substances to maintain and disclose long-tail environmental liability reserves on their balance sheets.
• Tie executive accountability to environmental compliance at every operating site, including leased facilities.
• Mandate site-closure and soil-and-groundwater testing protocols before any lease is surrendered, so contamination cannot be left behind unrecorded.
