Aerial Video of Alabama Oil Spill Exposes Inadequate Cleanup
Every year, we hear about the latest oil spills, pipeline explosions and pollution…but we rarely see how people and environment are impacted over time. Public Herald is embarking on a new series “American Albatross” to investigate the environmental legacy of fossil fuel in America and solutions for cleaning it up. We begin in Aliceville, Alabama.
Efforts to clean up an Alabama oil spill are under scrutiny after a train carrying 2.7 million gallons of North Dakota Bakken crude oil exploded last month, spilling into wetlands just outside the town of Aliceville. Photojournalist John Wathen captured video of cleanup efforts one week after the Nov. 7 derailment, and the footage prompts questions about the efficacy of methods being used.
Wathen wasn’t the only citizen responder in Aliceville, AL. He was joined by Scott Smith, who’s visited major oil spills across the globe to deploy his biodegradable technology, OPFLEX, that can absorb oil and other toxins from polluted water. Wathen and Smith tried to reach the wetland to assess the damage and help stop the oil from moving downstream. But they were turned away by railroad personnel and threatened with the FBI. Genesee & Wyoming railroad spokesperson Michael Williams wouldn’t confirm or deny the FBI’s involvement and redirected Public Herald to the Bureau.
The footage captured by Wathen shows clean up workers spraying what appears to be water into the oil spill.
After seeing Wathen’s footage, Smith wrote to the railroad company, Genesee & Wyoming, to express his concerns about the methods being used to clean up the spill:
It appears from the photos sent to me that water is being used to spray down the oil in the wetlands surrounding Aliceville, AL. There are much better options to remove the oil and help prevent further damage to the wetlands. If it rains anytime soon, there is little doubt that the oil in the water will spread downstream and things can be done now to prevent this.
Smith believes his own technology may be a better way. After the 2010 Deepwater Horizon disaster in the Gulf of Mexico, Smith sold BP more than 2 million square feet of OPFLEX for cleanup. OPFLEX is an open-celled, sponge-like material modeled after the human lung and sometimes takes the shape of eelgrass to absorb oil and other toxins from polluted water, both on and below the surface.
According to Williams, the spray method revealed in Wathen’s footage is “a process used to corral the oil within the containment booms prior to skimming.” However, workers appear to be spraying away from booms in some instances and towards unprotected shorelines. Smith believes the workers are actually using an outdated, defunct “dilution is the solution to pollution” method.
U.S. Environmental Protection Agency (EPA) Region IV, who responded to the spill, was not available for initial comment about the spraying.
According to Smith, when water is sprayed onto a shale oil spill, some toxins mixed with the oil dissolve below the surface of the water. Some of these toxins are naturally-occurring and some are byproducts of the drilling process used to extract Bakken crude, called fracking, which involves hundreds of chemicals that return to the surface with recovered oil.
How Are Oil Spills Cleaned Up?
In nearly all oil spills, containment booms are used as floating buffers to try and corral oil resting on the surface of water for skimming. Preventing oil from reaching shore is a major concern, given that oil is virtually impossible to remove from soil. The EPA and industry alike also use absorbent padding at waters edge in order to try and keep the oil off the shore.
When asked about the railroad’s cleanup efforts, Williams wrote to Public Herald that “air and water monitoring began on the morning of the derailment, and the site will be remediated.”
The railroad has a top oil-cleanup contractor on site who is experienced with crude oil responses for pipelines, exploration companies, railroads and shipping companies and has an established working relationship with EPA Region IV and the State of Alabama. The railroad is working closely with the EPA who are on site daily.
Williams later added their “top oil-cleanup contractor” is U.S. Environmental Services (USES), the same company involved in cleanup efforts of the 2010 BP Deepwater Horizon oil disaster in the Gulf of Mexico and others.
Of course, part of remediation involves knowing precisely how and what’s been spilled. Though the cleanup and investigation of how the train derailed and exploded in Alabama is ongoing, Williams informed Public Herald that the railway was up and running ten days after the incident and trains carrying Bakken crude are being diverted around Aliceville.
Series of Spills Reveals Crude Trend
Four months before the Alabama spill, Smith visited another oil train disaster in Lac-Mégantic, Quebec, where railcars—also carrying Bakken crude oil—derailed and exploded killing more than 40 people and decimating half the town.
CBC News Montreal reported in August that the “U.S. Department of Transportation…authorities were worried prior to the Lac-Mégantic disaster about the transport of oil from North Dakota on trains.” Another CBC News report states that Lac-Megantic investigators found it “unusual for crude oil to burn so fiercely.”
Smith has sampled and tested Bakken crude. According to him, not only is Bakken crude lighter and more volatile than other oils, but no one is testing or “fingerprinting” each shipment before placing it in railcars or pipelines for transport. “The objective is to pump it and load it,” Smith told CBC News Montreal.
Smith offered his test results to help with Genesee & Wyoming’s ongoing investigation. “I have done baseline fingerprinting of Bakken crude oil in its ‘pure form’…This data might help Genesee & Wyoming assess exactly what was in the tankers that exploded.”
CBC News also reported tests of Bakken crude by one oil company which showed ten times the amount of benzene in Bakken oil as compared with others, as well as hydrogen sulfide, leading some experts to wonder about the crude’s propensity to easily ignite.
Like Smith, John Wathen has responded to many environmental disasters. As Hurricane Creekkeeper of the international Waterkeeper Alliance, Wathen responded to the 2008 Kingston coal ash disaster in Tennessee and the BP Gulf of Mexico spill in 2010, which won him the honor of being named 2012 River Hero. His documentation of these incidents gives a close-up look at how spills are handled.
Aliceville is just the latest in a series of spill disasters in North America, topping a growing list of incidents related to fossil fuel’s production, transport, distribution, and waste disposal. Setting aside natural gas facility explosions and coal ash spills, here’s a list of some of the oil spill disasters in the U.S., or involving U.S. companies, in just the last three years:

"Best" Method of Transporting Oil
Due to a surge in American fossil fuel production in recent years, oil-by-rail has become an alternative for many companies at a time when pipelines are taboo, crowned in controversy by the Keystone XL. The L.A. Times reported in September that railroads are carrying 25 times more crude oil than they were five years ago.
Genesee & Wyoming’s Michael Williams wrote to Public Herald, “Rail is the safest means of ground-freight transportation…As a common carrier, the railroad has a legal obligation to transport these materials.”
Both railways and pipelines can be "common carriers" which are legally required to carry all freight, if space allows and fees are paid, and may not refuse unless reasonable grounds exist. Under international law, a common carrier is liable for damage to freight as well, with four exceptions: “An act of nature, an act of the public enemies, fault or fraud by the shipper, [or] an inherent defect in the goods.”
Whether pipelines or railways are "safer" for transport of hazardous materials like crude oil is debatable, but writer Russ Blinch gives an interesting analogy:
Looking at pipelines versus rail tankers is really like asking, “Should I drive the car with bad brakes or the one with bad tires?
For those living along routes for transporting hazardous materials, whether by pipe or by rail, it’s unlikely anyone’s taken time to ask which methods or cleanup technology communities prefer industry use.

The ghoulishly named ogre-faced spider can "hear" with its legs and use that ability to catch insects flying behind it, the study published in Current Biology Thursday concluded.
"Spiders are sensitive to airborne sound," Cornell professor emeritus Dr. Charles Walcott, who was not involved with the study, told the Cornell Chronicle. "That's the big message really."
The net-casting, ogre-faced spider (Deinopis spinosa) has a unique hunting strategy, as study coauthor Cornell University postdoctoral researcher Jay Stafstrom explained in a video.
They hunt only at night using a special kind of web: an A-shaped frame made from non-sticky silk that supports a fuzzy rectangle that they hold with their front forelegs and use to trap prey.
They do this in two ways. In a maneuver called a "forward strike," they pounce down on prey moving beneath them on the ground. This is enabled by their large eyes — the biggest of any spider. These eyes give them 2,000 times the night vision that we have, Science explained.
But the spiders can also perform a move called the "backward strike," Stafstrom explained, in which they reach their legs behind them and catch insects flying through the air.
"So here comes a flying bug and somehow the spider gets information on the sound direction and its distance. The spiders time the 200-millisecond leap if the fly is within its capture zone – much like an over-the-shoulder catch. The spider gets its prey. They're accurate," coauthor Ronald Hoy, the D & D Joslovitz Merksamer Professor in the Department of Neurobiology and Behavior in the College of Arts and Sciences, told the Cornell Chronicle.
What the researchers wanted to understand was how the spiders could tell what was moving behind them when they have no ears.
It isn't a question of peripheral vision. In a 2016 study, the same team blindfolded the spiders and sent them out to hunt, Science explained. This prevented the spiders from making their forward strikes, but they were still able to catch prey using the backwards strike. The researchers thought the spiders were "hearing" their prey with the sensors on the tips of their legs. All spiders have these sensors, but scientists had previously thought they were only able to detect vibrations through surfaces, not sounds in the air.
To test how well the ogre-faced spiders could actually hear, the researchers conducted a two-part experiment.
First, they inserted electrodes into removed spider legs and into the brains of intact spiders. They put the spiders and the legs into a vibration-proof booth and played sounds from two meters (approximately 6.5 feet) away. The spiders and the legs responded to sounds from 100 hertz to 10,000 hertz.
Next, they played the five sounds that had triggered the biggest response to 25 spiders in the wild and 51 spiders in the lab. More than half the spiders did the "backward strike" move when they heard sounds that have a lower frequency similar to insect wing beats. When the higher frequency sounds were played, the spiders did not move. This suggests the higher frequencies may mimic the sounds of predators like birds.
University of Cincinnati spider behavioral ecologist George Uetz told Science that the results were a "surprise" that indicated science has much to learn about spiders as a whole. Because all spiders have these receptors on their legs, it is possible that all spiders can hear. This theory was first put forward by Walcott 60 years ago, but was dismissed at the time, according to the Cornell Chronicle. But studies of other spiders have turned up further evidence since. A 2016 study found that a kind of jumping spider can pick up sonic vibrations in the air.
"We don't know diddly about spiders," Uetz told Science. "They are much more complex than people ever thought they were."
Learning more provides scientists with an opportunity to study their sensory abilities in order to improve technology like bio-sensors, directional microphones and visual processing algorithms, Stafstrom told CNN.
"The point is any understudied, underappreciated group has fascinating lives, even a yucky spider, and we can learn something from it," he told CNN.
