Seattle Sues Monsanto Over PCB Contamination, Becomes 6th City to Do So

Seattle joins the growing list of cities in the American West that has slapped Monsanto with a PCB lawsuit. PCBs, or polychlorinated biphenyls, is a highly toxic chemical that the company manufactured decades ago.

The complaint, filed on Monday with the U.S. District Court in Seattle, alleges that Monsanto knew that the chemicals were polluting the environment and causing harm to people and wildlife, as Seattle City Attorney Pete Holmes explained to The Seattle Times.

“When the profit motive overtakes concern for the environment, this is the kind of disaster that happens,” Holmes added. “I’m proud to hold Monsanto accountable.”

According to Seattlepi.com, the suit concerns PCB contamination in 20,000 acres that drain into the lower Duwamish, which is a federal Superfund site (meaning it's so polluted that that the U.S. Environmental Protection Agency has to help with cleanup). It also concerns areas that drain to the East Waterway adjacent to Harbor Island, also a federal Superfund site.

The lawsuit also states:

PCBs were detected in 75 percent of more than 1,000 samples collected from catch basins and drainage lines in the Lower Duwamish drainage area. In the East Waterway drainage areas, PCBs were detected in 82 percent of samples collected with “in-line grabs” of sediment in drainage pipes and PCBs were detected in 73 percent of samples collected from catch basins in street right-of-ways.

The city is likely seeking millions of dollars from Monsanto to pay for the cleanup. "The ultimate cost depends on how far you go in cleanup," Holmes told Seattlepi.com, adding that it would be "impossible" clean up all the PCBs found mainly in the city's industrial zone.

Under a consent decree issued by the Environmental Protection Agency (EPA) and the Washington Department of Ecology, Seattle already needs to spend at least $27 million to build a treatment plant to remove pollutants, including PCBs, from stormwater.

However, as The Seattle Times pointed out, the plant will only cover a mere 1.25 percent of the 20,000 acres that drain to the Lower Duwamish.

Monsanto has faced a spate of PCB contamination lawsuits over the decades and several this year alone. In 2015, the cities of Spokane, San Diego, San Jose and Oakland also sued the company over PCB-contaminated sites.

Before switching to agribusiness, Monsanto was the primary manufacturer of PCBs in the U.S. from 1935 to 1979. PCBs, which were used to insulate electronics, was banned in 1979 by the U.S. EPA over human health and environmental concerns.

The chemical has been detected in waterways around the world, and can cause damage to aquatic life, wildlife as well as human health. PCBs have been known to negatively effect the human immune, reproductive, nervous and endocrine systems, and cause cancer.

In an email to KUOW/EarthFix, Monsanto spokeswoman Charla Lord said the company is reviewing the lawsuit and its allegations but added that “Monsanto is not responsible for the costs alleged in this matter.”

“PCBs sold at the time were a lawful and useful product that was then incorporated by third parties into useful products," she wrote. "If improper disposal or other improper uses allowed for necessary clean up costs, then these other third parties would bear responsibility for those costs.”

It has been reported that Monsanto allegedly knew that PCBs were toxic well before the 1979 ban but continued production of the profitable compound anyway. Think Progress reported:

In a 1970 internal memo, agrochemical giant Monsanto alerted its development committee to a problem: Polychlorinated Biphenyls—known as PCBs—had been shown to be a highly toxic pollutant.

PCBs—sold under the common name Aroclor—were also huge business, raking in some $10 million in profits. Not wanting to lose all of these profits, Monsanto decided to continue its production of Aroclor while alerting its customers to its potentially adverse effects. Monsanto got out of the PCB business altogether in 1977—two years before the chemicals were banned by the EPA—but just because the company no longer produces the toxic substances doesn’t mean it can forget about them completely.

If asked to recall a hurricane, odds are you'd immediately invoke memorable names like Sandy, Katrina or Harvey. You'd probably even remember something specific about the impact of the storm. But if asked to recall a heat wave, a vague recollection that it was hot during your last summer vacation may be about as specific as you can get.

Scientists have found a way to use bricks as batteries, meaning that buildings may one day be used to store and generate power. Public Domain Pictures

One of the challenges of renewable power is how to store clean energy from the sun, wind and geothermal sources. Now, a new study and advances in nanotechnology have found a method that may relieve the burden on supercapacitor storage. This method turns bricks into batteries, meaning that buildings themselves may one day be used to store and generate power, Science Times reported.

Bricks are a preferred building tool for their durability and resilience against heat and frost since they do not shrink, expand or warp in a way that compromises infrastructure. They are also reusable. What was unknown, until now, is that they can be altered to store electrical energy, according to a new study published in Nature Communications.

The scientists behind the study figured out a way to modify bricks in order to use their iconic red hue, which comes from hematite, an iron oxide, to store enough electricity to power devices, Gizmodo reported. To do that, the researchers filled bricks' pores with a nanofiber made from a conducting plastic that can store an electrical charge.

The first bricks they modified stored enough of a charge to power a small light. They can be charged in just 13 minutes and hold 10,000 charges, but the challenge is getting them to hold a much larger charge, making the technology a distant proposition.

If the capacity can be increased, researchers believe bricks can be used as a cheap alternative to lithium ion batteries — the same batteries used in laptops, phones and tablets.

The first power bricks are only one percent of a lithium-ion battery, but storage capacity can be increased tenfold by adding materials like metal oxides, Julio D'Arcy, a researcher at Washington University in St. Louis, Missouri, who contributed to the paper and was part of the research team, told The Guardian. But only when the storage capacity is scaled up would bricks become commercially viable.

"A solar cell on the roof of your house has to store electricity somewhere and typically we use batteries," D'Arcy told The Guardian. "What we have done is provide a new 'food-for-thought' option, but we're not there yet.

"If [that can happen], this technology is way cheaper than lithium ion batteries," D'Arcy added. "It would be a different world and you would not hear the words 'lithium ion battery' again."

One of the concerns about a warming planet is the feedback loop that will emerge. That is, as the planet warms, it will melt permafrost, which will release trapped carbon and lead to more warming and more melting. Now, a new study has shown that the feedback loop won't only happen in the nether regions of the north and south, but in the tropics as well, according to a new paper in Nature.
