Thallium isotopes reveal that rapid marine oxygen fluctuations in the Late Ordovician oceans are linked to mass extinction pulses. 

In order to understand the extent to which airborne PFAS emission can impact soil and groundwater, we conducted a sampling campaign in areas of conserved forest lands near Bennington, VT/Hoosick Falls, NY. This has been home to sources of PFAS air-emissions from Teflon-coating operations for over 50 years. Since 2015, the Vermont and New York Departments of Environmental Conservation have documented ∼1200 residential wells and two municipal water systems across a 200 km 2 area contaminated with perfluorooctanoic acid (PFOA). Given the large areal extent of the plume, and the fact that much of the contaminated area lies up-gradient and across rivers from manufactures, we seek to determine if groundwater contamination could have resulted primarily from air-emission, land deposition, and subsequent leaching to infiltrating groundwater. Sampling of soils and groundwater in the Green Mountain National Forest (GMNF) downwind of factories shows that both soil and groundwater PFOA contamination extend uninterrupted from inhabited areas into conserved forest lands. Groundwater springs and seeps in the GMNF located 8 km downwind, but >300 meters vertically above factories, contain up to 100 ppt PFOA. Our results indicate that air-emitted PFAS can contaminate groundwater and soil in areas outside of those normally considered down-gradient of a source with respect to regional groundwater flow. 

ABSTRACT Contamination offers a new observatory for anthropological theory. But does it bring us closer to the world at hand? I have spent the past five years working with residents in Bennington, Vermont, and Hoosick Falls, New York, in pursuit of justice after the toxin PFOA was discovered in their drinking water. Turning from advocacy to writing, I've been struck by how prominent toxicity is becoming in certain currents of anthropological theory and how little those theories illuminate about the protests against contamination I participated in. As the theoretical dazzle of contamination surges forward toward experimental futures, planetary futures, and queer futures, toxicity can become an oracle whose ethnographic significance lies more in its prophetic intimation than in its present inhabitation. Staying close to the experience of a New England community protesting industrial pollution, I show how the ethnographic realities of contamination can orient theory for a better world without first resigning us to the loss of the present.

Is the environment worth the effort? The environment often seems far too easy, far too obligatory, and far too footloose a concept to warrant serious attention. It somehow evokes both bookish abstraction and populist rousing, it cobbles together science and advocacy only to blunt their conjoined insights, and it continues to elude fixed definition even while basking in stately recognition. The banalities of this mess can give the impression that the environment has no real history, no critical content, and heralds no true rupture of thought and practice. The environment, in the eyes of some, is mere advertising. If there is a story to the environment, others suggest, it’s largely one of misplaced materialism, middle class aesthetics, and first world problems. Such has been the sentiment, such has been the dismissal. In the rush to move past the environment, few have attended to the history of the concept. This is curious as the constitution of the environment remains a surprisingly recent achievement. In the late 1960s and early 1970s, the environment shifted from an erudite shorthand for the influence of context to the premier diagnostic of a troubling new world of induced precarity (whether called Umwelt, l’environnement, medio ambiente, huanjing, mazingira, or lingkungan). The environment – a term “once so infrequent and now becoming so universal,” as the director of the Nature Conservatory commented in 1970 (Nicholson: 5) – soon came to monopolize popular and scientific understandings of damaged life and the states’ obligation to it worldwide. Even as the environment has been immensely productive for research and policy in the following decades, the formation of the environment itself remains understudied. In the United States, this is particularly clear in two aspects of the environment: 1) the role of fossil fuels in making the environment visible, factual, and politically operable; and 2) the precocious if weightless critique authorized by the environment.
