Our article analyzes interdisciplinary literature within the social sciences on outcomes of environmental cleanups at Superfund, brownfield, and other contaminated sites. By focusing on postremediation sites and outcomes, we expand the understanding of the sociopolitical life of contaminated sites over time. First, we examine the technoscientific practices of how scientists and environmental managers seek to make cleanup outcomes legible and meaningful. Next, we engage with a wider array of literature on pollution/toxicity, uncovering circular temporalities in cleanup processes along with continuities in pollution/toxicity and in political struggle. Finally, we examine the social worlds of postremediation landscapes, drawing attention to how cleanups create new relationships among people, history, and nature. In conclusion, we identify areas of opportunity for these insights to inform the conceptualization and evaluation of cleanup outcomes in ways that better incorporate the complex dynamics of postremediation
social worlds.
