New Film 'Dark Waters' Shines Light on Chemical Pollution History in Ohio River Valley
By Sharon Kelly
Dark Waters, the new film starring Mark Ruffalo as attorney Rob Bilott, is set in the Ohio River Valley city of Parkersburg, West Virginia — a place about 150 miles downstream from where Shell is currently building a sprawling plastics manufacturing plant, known as an "ethane cracker," in Beaver, Pennsylvania.
Ruffalo's film, directed by Todd Haynes, debuted to critical acclaim, earning a Rotten Tomatoes critics' rating of 91 percent, with The Atlantic calling it a "chilling true story of corporate indifference."
While much of Dark Waters, as the title suggests, centers on contaminated water, the story of perfluorooctanoic acid (PFOA), the Teflon-linked chemical at the heart of the film, is also a story about air pollution. And as much as the film looks back to history, DuPont's pollution — and the company's decades-long cover-up — may gain new relevance as the chemical industry plans a multi-billion dollar expansion, fed by fracked fossil fuels, along the banks of the Ohio.
The film begins as a detective story set in the 1990s, as Bilott, a corporate defense attorney, begins investigating the bizarre deaths of cattle in a farming region he'd visited as a child. Bilott discovers the chemical culprit's identity less than an hour into the 2 hour and 7 minute film — and then spends the remainder of the movie pitting his personal tenacity against the DuPont corporation's deep-pocketed endurance, as even partners at Bilott's own law firm question his work.
The movie highlights DuPont's legal maneuvering, showing the company seeking to evade liability by "notifying" customers that the chemical was in their water at levels the notice suggested were "safe" — starting a time clock running for the statute of limitations on DuPont's liability.
The film's extended runtime mirrors the duration of Bilott's real-life legal battles with DuPont, which began as a single civil suit on behalf of farmer Wilbur Tennant but gradually expanded to become one of the largest medical monitoring lawsuits in U.S. history. Real impacted people, including Bucky Bailey and Parkersburg elementary school teacher Joe Kiger and his wife, appear on screen along Ruffalo, Anne Hathaway and Tim Robbins, playing themselves in roles that layer an aura of realism onto the tale.
A Chemical History
Beyond the Ohio River Valley, PFOA, which according to a 2016 U.S. Environmental Protection Agency fact sheet, can cause cancer, harm to fetuses, immune system issues and other health problems, has spread rapidly around the world.
First developed in the lab less than a century ago, PFOA can now be found in the bloodstreams of an estimated 99.7 percent of Americans, according to the Centers for Disease Control and Prevention, and in wildlife ranging from polar bears to dolphins to bald eagles. Once released, PFOA and the hundreds of other PFAS chemicals like it may take millennia to break down. Tied together by one of nature's strongest known chemical bonds, the carbon-fluorine bond, the molecule doesn't naturally degrade from exposure to light or water to break down over time. Instead, it bioaccumulates in the bloodstream, building up and exposing those higher up the food chain to progressively higher levels of the chemical.
Bilott's class action lawsuit centers on the water contamination from PFOA, which DuPont started using to produce its nonstick coating Teflon at its Parkersburg plant in 1951. His plaintiffs were customers of six water districts along the Ohio River on both the West Virginia and Ohio sides of its banks.
But while DuPont buried drums of the PFOA waste on the banks of the Ohio and otherwise disposed of its waste — in part, long before the nation's cornerstone environmental laws were written — PFOA itself is also a powdery dust that readily becomes airborne — and the Ohio River is lined on both sides by tall hills that can at times trap air pollution in the valley, where coal and steel towns dot the riverbanks.
Documents obtained by Bilott's legal team show DuPont slowly realized the dangers that the mix of air pollution and steep hills posed to the surrounding communities. In fact, one DuPont lawyer later privately bemoaned the fact that the company, which had been secretly testing the water for decades, hadn't checked for PFOA in the air.
"We also learned that not only do we have people drinking our famous surfactant (PFOA), but levels in ambient air above our guidelines, sure we have margins of safety in our number, but we should have checked this years ago and taken steps to remedy, guess the hills on the other side of the river cause great conditions for high ambient levels, the plume hits them before it can disperse more fully," DuPont attorney Bernard Reilly wrote in an August 9, 2001 email. "Ugh."

PFOA's ability to become airborne may have helped it spread to some of the furthest reaches of the globe.
"The state of North Carolina has demonstrated atmospheric deposition of PFAS many miles downwind from a manufacturing facility," the Michigan Department of Environment said in a Q&A on the chemicals. "New Hampshire found contaminated groundwater was caused by atmospheric deposition of PFAS from industrial emissions of PFAS. Additionally, PFAS have been sampled and found in remote regions such as the Arctic."
In 2001, DuPont's attorney wrote that one scientist was so concerned about the PFOA air pollution in the valley that she suggested residents should wear masks. "Dr. Staats on our call last week seemed determined to assign a large does [sic] to air since that route of exposure is more difficult to deal with (e.g. she said it might require the public to wear 'gas masks'), of course she is aware of the recent dispersion modeling from the plant," Reilly wrote on Oct. 7 of that year.

DuPont also worked hard to pressure state environmental regulators to move slowly in response to the harms from PFOA — not because the dangers weren't real, but because the air pollution in the valley hadn't been accounted for.
"I go to Charleston Monday for a meeting Tuesday with WV regulators, we are also trying to convince them there is no emergency," Reilly wrote in an Oct. 13, 2001 email. "… [W]e are hoping [an independent agency] would actually agree to higher levels than we have been saying, if for no reason than we are exceeding the levels we say we set as our own guideline, mostly because no one bothered to do the air modeling until now, and our water test has been completely inadequate (until next week)."

Chemical Lessons for the Future
With an expanding petrochemical industry eyeing the Ohio as the site for tens of billions of dollars' worth of new petrochemical and plastic production, some in Parkersburg are wary of the environmental — and political — lessons from PFOA. Ohio and West Virginia have been slower than other states to respond to the pollution, reporter Nicholas Brumfield wrote in a piece published by expatalachians.
"For Parkersburg's Eric Engle, this inaction [on regulating PFAS in West Virginia and Ohio] is linked to the powerful influence of local petrochemical industries," Brumfield wrote. "'We have politicians still investing in petrochemicals to save the oil and gas industry … They're wanting to store ethane here now. We're still learning about the dangers of all these petrochemicals … We have to move past it,' Engle said.
It's worth observing that DuPont's PFOA pollution began long before today's federal environmental laws were written, like the Clean Water Act, the Clean Air Act and the Safe Drinking Water Act. Nonetheless, some in the Ohio River Valley remain concerned about the impacts that permitted pollution from new petrochemical projects could have.
"As I sat and watched the newly released movie Dark Waters, I thought, 'This could be the future of the Ohio River Valley,'" Randi Pokladnik, a retired research chemist who volunteers for the Ohio Valley Environmental Coalition, wrote in a Dec. 13 letter to the editor published by the Columbus Dispatch. "Ohio's regulatory agencies know millions of tons of toxins will be coming out of the plastics cracker smokestacks and into the air. They know toxic organic compounds will be flowing into the Ohio River."
Midway through Dark Waters, Darlene Kiger (played by Mare Winningham) describes the "Teflon flu" that workers, including her ex-husband — who used PFOA — developed. "We knew something wasn't right," Kiger says. "But this house, we bought it just by showing the bank my husband's DuPont ID. Put both our kids through college, engineers. And, in this town, that doesn't come without a price."
That's a moral dilemma that may confront more residents along the Ohio if the petrochemical industry arrives en masse (though it's worth noting that DuPont's Parkersburg plant employed 2,000 directly and roughly 1,000 more contractors, while modern petrochemical plants like Shell's ethane cracker in Beaver will employ an expected 600).
In the meantime, Dark Waters offers a look back at the extraordinary tenacity — and at times, simple luck — it took for those outside DuPont's inner circle to begin to understand the hazards and the harms the company's chemical contamination had caused.

If weather is your mood, climate is your personality. That's an analogy some scientists use to help explain the difference between two words people often get mixed up.
Size Matters<p>Climates are a bit like woven tapestries. The big picture is important, no question. But so are all the seemingly minor details found inside the larger whole.</p><p><a href="https://research-information.bris.ac.uk/en/persons/tommaso-jucker" target="_blank">Tommaso Jucker</a> is an environmental scientist at the University of Bristol. In an email, Jucker says he'd define the term microclimate as "the suite of climatic conditions (temperature, rainfall, humidity, solar radiation) measured in localized areas, typically near the ground and at spatial scales that are directly relevant to ecological processes."</p><p>We'll talk about that last bit in a minute. But first, there's another criteria to discuss. According to some researchers, a microclimate — by definition — must differ from the larger area that surrounds it.</p><p><a href="https://www.cfc.umt.edu/research/paleoecologylab/publications/Davis_et_al_2019_Ecography.pdf" target="_blank">Forests</a> provide us with some great examples. "The climate near the ground in a tropical rainforest is dramatically different from the climate in the canopy 50 meters [164 feet] above," says University of Montana ecologist <a href="https://www.cfc.umt.edu/personnel/details.php?ID=1110" target="_blank">Solomon Dobrowski</a> in an email. "This vertical gradient among other factors allows for the staggering biodiversity we see in the tropics."</p><p>Likewise, scientists observed that a 2015 partial <a href="https://animals.howstuffworks.com/insects/bees-stopped-buzzing-during-2017-solar-eclipse.htm" target="_blank">solar eclipse</a> caused the air temperature of an Eastern European meadow to <a href="https://rmets.onlinelibrary.wiley.com/doi/full/10.1002/wea.2802" target="_blank">change more dramatically</a> than it did in a nearby forest. That's because trees provide not only shade, but their leaves also reflect solar radiation. At the same time, forests tend to reduce wind speeds.</p><p>All those factors add up. A 2019 review of 98 wooded places — spread out across five continents — found that forests are 7.2 degrees Fahrenheit (4 degrees Celsius) <a href="https://natureecoevocommunity.nature.com/posts/47363-forests-protect-animals-and-plants-against-warming" target="_blank">cooler on average</a> than the areas outside them.</p><p>Now if you hate the cold, don't worry; there's a cozy exception to the rule. According to that same study, forests are usually 1.8 degrees Fahrenheit (1 degree Celsius) warmer than the external environment during the wintertime. Pretty cool.</p>
A Bug's Life<p>When does a microclimate stop being, well, micro? In other words, is there a maximum size we should be aware of when discussing them?</p><p>Depends on who you ask. "In terms of horizontal scale, some have defined 'microclimate' as anything that is less than 100 meters [328 feet] in range," Jucker says. "I'm personally less prescriptive about this."</p><p>Instead, he says the "scale at which we want to measure [a particular] microclimate" ought to be "dictated" by the questions we're trying to answer.</p><p>"If I want to know how temperature affects the photosynthesis of a leaf, I should be measuring temperature at centimeter scale," Jucker explains. "If I want to know if and how temperature affects the habitat preference of a large, mobile mammal, it's probably more relevant to capture temperature variation across [tens to hundreds] of meters."</p><p>For instance, solitary plants have the power to generate itty-bitty microclimates. Just ask <a href="https://www.colorado.edu/geography/peter-blanken-0" target="_blank">Peter Blanken</a>, a geography professor at the University of Colorado, Boulder and the co-author of the 2016 book, "<a href="https://amzn.to/2XN6FT8" target="_blank">Microclimate and Local Climate</a>."</p>
The urban heat island effect is a good example of how microclimates work. NOAA
Microclimates on a Grand Scale<p>It's no secret that our planet is going through some rough times at the macro level. The global temperature is <a href="https://climate.nasa.gov/vital-signs/global-temperature/" target="_blank">climbing</a>; nine out of the <a href="https://www.noaa.gov/news/2019-was-2nd-hottest-year-on-record-for-earth-say-noaa-nasa" target="_blank">10 hottest years on record</a> have occurred since 2005. And by one recent estimate, roughly 1 million species around the world are <a href="https://ipbes.net/sites/default/files/2020-02/ipbes_global_assessment_report_summary_for_policymakers_en.pdf" target="_blank">facing extinction</a> due to human activities.</p><p>"One of the big questions that ecologists and environmental scientists are trying to answer right now is how will individual species and whole ecosystems respond to rapid climate change and habitat loss," says Jucker. "...To me, [microclimates are] a key component of this research — if we don't measure and understand climate at the appropriate scale, then predicting how things will change in the future becomes a lot harder."</p><p>Developers have long understood the impact small-scale climates have on our daily lives. <a href="https://science.howstuffworks.com/environmental/green-science/urban-heat-island.htm#pt0" target="_blank">Urban heat islands</a> are cities that have higher temperatures than neighboring rural areas.</p><p>Plants release vapors that can moderate local climates. But in cities, natural greenery is often scarce. To make matters worse, plenty of our roads and buildings have a bad habit of absorbing or re-emitting heat from the sun. <a href="https://www.google.com/books/edition/Microclimate_and_Local_Climate/LHUZDAAAQBAJ?hl=en&gbpv=1&bsq=urban%20heat%20island" target="_blank">Vehicle emissions</a> don't exactly help the situation.</p><p>Still, it's not like Boston or Beijing are thermal monoliths. Sometimes, the documented temperatures <a href="https://e360.yale.edu/features/can-we-turn-down-the-temperature-on-urban-heat-islands" target="_blank">within a single city</a> vary by 15 to 20 degrees Fahrenheit (8.3 to 11.1 degrees Celsius).</p><p>That's where metro parks and city trees come in. They have nice cooling effects on nearby neighborhoods. "Several cities around the world have developed programs to increase urban green spaces," says Blanken. "Tree planting programs and green roof programs, have been shown to lower surface temperatures, decrease air pollution and decrease surface water runoff (urban flash-flooding) in urban areas."</p>

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.

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.
