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.
