Deepwater Horizon, 5 Years Later

On April 20th 2010, BP’s Deepwater Horizon oil rig exploded, killing eleven workers and triggering the spill of nearly 5 million barrels of crude oil into the Gulf of Mexico. The accident wreaked massive damage on marine and coastal ecosystems, caused myriad negative health effects in cleanup workers, and gutted the Gulf Coast economy. Five years later, it remains the largest offshore environmental disaster in the history of the United States. Environmental effects from the disaster linger and the debate around offshore drilling for oil continues. Meanwhile, Gulf Coast residents are still writing a story of resilience and recovery in the years following the disaster.

In the immediate aftermath of the spill, water quality was drastically impaired in the Gulf of Mexico. Concentrations of cancer-causing polycyclic aromatic hydrocarbons (PAHS) skyrocketed in the waters off the coast of Louisiana, and were also found at elevated levels in the ocean near Alabama, Mississippi, and Florida. The spill threatened dozens of marine species with elevated risks of extinction. Residents and cleanup workers experienced health effects from exposure to both the toxic organic compounds that composed the spill, and from the cleanup process itself. Toxic dispersants were used in the cleanup process, causing illnesses that gravely affected cleanup workers.

After five years the acute effects of the spill have passed, but marine species are still dying at accelerated rates and tar balls continue to wash up on the shores as oil that was buried under sand at the time of the spill resurfaces. Researchers have also begun to investigate the possibility of long-term health damage in cleanup workers. As debate surrounding offshore drilling continues, the BP oil spill has added a horrific cautionary tale to the annals of what many hope will be the key to solving our energy crisis.  The lingering environmental and health effects from the spill ensure that the BP oil disaster will not soon be forgotten…and thanks to one groundbreaking citizen journalism initiative, neither will the stories of those most closely affected by the disaster.

The Bridge the Gulf Project is a community media project founded in 2010 following the BP disaster. For the past five years, the organization has worked to elevate the voices of Gulf Coast communities as they work to enhance sustainability and social justice. The Project is organized by a network of community leaders, experts and writers, and spotlights stories that are seldom heard in the mainstream media, while providing training and support for those engaged in regional movement-building. Many of the stories center on environmental activism. On April 19th, one blogger wrote of being arrested at BP America’s headquarters; another recent post covers environmental justice mapping initiatives; and last month, one BP spill cleanup worker spoke out about his health issues. However, media featured on the site also cover topics ranging from immigration to racial justice.

In the immediate and long-term wake of environmental disasters, it is often the stories of failure and tragedy that dominate the mainstream media. Bridge the Gulf offers an alternative to this often dehumanizing coverage, elevating the voices of those most responsible for the complex recovery from an environmental accident that intersects with many other social and economic injustices.

BTEX and Endocrine Disruption

A new study has revealed the possible association between BTEX compounds (benzene, toluene, ethylbenzene, and xylenes) and endocrine disruption at levels way below the reference concentrations used by U.S. Environmental Protection Agency (EPA).

BTEX chemicals are volatile organic compounds (VOCs) that are used as solvents in consumer and industrial products, as gasoline additives, and as intermediates in the synthesis of organic compounds for many consumer products. As a result, they are prevalent in our environment, especially in indoor settings. The current scientific understanding of these chemicals is that they can cause skin and sensory irritation, central nervous system problems and effects on the respiratory system at acute short-term exposures; and kidney, liver and circulatory problems as well as leukemia and other forms of cancer at chronic long-term exposures.

However, this new study points to the role of BTEX chemicals in hormone disruptions, a field of study pioneered by the late Theo Colborn. In fact, Theo contributed personally to this study before her passing along with scientist from the The Endocrine Disruption Exchange (TEDX) (the international non-profit she founded) and the University of Colorado, Boulder. Although direct association can be made between endocrine disruption and BTEX exposure, this study points to the real need to examine this link more closely. Cathy Milbourn, a spokesperson for the EPA, said in an emailed response that the agency will “review the study and incorporate the findings into our work as appropriate.”
