Lingering Poison: My Witness to Deepwater Horizon’s Legacy on the Gulf Coast

As the mother of a childhood cancer survivor from a coastal Alabama cluster, I reflect on the 15th anniversary of the Deepwater Horizon disaster with anger and frustration at the countless lives needlessly destroyed by the spill and its “cleanup.” But more than anything, I am afraid… I am afraid because the same chemicals that wrought havoc on Gulf communities aren’t being disposed of—they are being rebranded to be reused.

During my seven years of assisting cleanup workers at a Miami-based law firm and Government Accountability Project, I saw the stuff of medical nightmares manifest in real life as I came face-to-face with an innocuously named monster: Corexit. Corexit is a chemical oil dispersant that was used liberally in the wake of the Deepwater Horizon disaster to break up oil slicks into smaller droplets that can be submerged underwater. While Corexit was once described as being “as safe as dish soap” by a BP executive, the final chapter of its use in the Deepwater Horizon disaster was not to be told via feel-good commercials of freshly cleaned ducklings. It is still being written by outsiders documenting the broken lives of the men and women who can no longer speak for themselves after volunteering to clean the Gulf.

Many of the men and women who volunteered to clean the Gulf, a body of water that bound together their communities, jobs, and very way of life, died in the months and years after exposure to Corexit, often from serious diseases including blood and pancreatic cancers—silencing their voices long before justice could be served. I personally knew dozens who were exposed and subsequently left the Earth far too soon.

The corporate shell game of rebranding these toxic chemicals under new names must not distract us from the fundamental truth that these dispersants should never be used again in our waters.

I still think about Captain Bill, who came to us when Stage 4 colon cancer appeared after running a supply boat to the sinking Deepwater Horizon rig. He did not believe all the hype from environmentalists about the dangers of dispersants until he got crop-dusted with them. He developed softball sized cysts all over his body filled with bacteria and was left with just months to live. He left behind a wife and three children, including a young son with autism.

I remember Sandra, a woman who always exuded joy during the 20 years I’d known her. Her job for BP required her to hop on and off oil-contaminated boats; she tragically developed a rare myeloproliferative disorder that ended her life at age 60. She left behind a husband who missed her so profoundly that he lasted only a few months without her.

Corexit has been proven to have deadly side effects within humans, but that won’t stop corporate greed from slapping a new label on it and sending it to a different country. The U.S. Environmental Protection Agency (EPA) was in the process of finalizing new rules and regulations governing the usage of oil dispersants. Right before the rules were set to be finalized, the manufacturer of Corexit abruptly discontinued its product line which constituted over 45% of globally stockpiled dispersants. This was likely not coincidental; the new EPA rules require manufacturers to truthfully report known or anticipated harm to human health and wildlife from their products. Corexit’s parent company chose to withdraw from the U.S. market while re-registering the same toxic products in the United Kingdom and Brazil in 2024, with France also considering approval.

People and communities were falsely reassured about the safety of the working conditions, as BP told workers personal protective gear was unnecessary when dealing with the chemicals. Now, with the risks and threats of exposure known, the protective gear could have saved hundreds of lives and communities from devastation.

Fifteen years after the Deepwater Horizon oil spill, the legacy of Corexit dispersants continues to manifest in the broken bodies and shattered lives of those who were exposed, including those who spoke out to save future generations. The corporate shell game of rebranding these toxic chemicals under new names must not distract us from the fundamental truth that these dispersants should never be used again in our waters. The time has come to close this dark chapter in our history and commit to solutions that truly protect both our coasts and the people who call them home.
