Research has explored the ways in which communities respond to local polluting facilities. In some cases, residents mobilize to confront corporate and state polluters, whereas in other cases residents remain quiescent in the wake of documented environmental threats. The variation in community response is often linked to demographic variables, including age, gender, education, and length of residence; yet cultural factors remain largely unexamined. We examine how cultural factors such as community identity and memory mitigate the relationship between community residents and polluting facilities. We present a comparative study of two heavily polluted communities-Blackwell, Oklahoma, and Cañon City, Colorado-that had divergent responses to contamination. The data for these cases come from in-depth interviews with community residents and various officials (N = 105), content analyses of newspaper coverage and relevant organization documents, and direct observation of meetings and organizing activities. Our findings indicate that cultural factors play a critical role in understanding the relationship between local residents and polluting facilities. We conclude by discussing the implications of our findings for future research on rural communities and environmental contamination.
