Three cross-sectional surveys were conducted in different regions of British Columbia, using a model of risk perception that divides the community into attitudinal and behavioral subgroups based on awareness and concern about waste management facilities. The three communities differed with respect to their levels of both awareness and concern about facilities, either planned for or situated in their region. Surprisingly, the most polarized community, which had nevertheless accepted a facility, rated this facility as more desirable than the other two communities. The unconcerned group in this community felt well informed, was more trusting of siting and operating agencies, and believed that the facility would generate benefits. The concerned group in this community also felt better informed, was more trusting of siting and operating agencies, and believed that its facility would generate benefits, compared with concerned groups in the other two communities. Longitudinal studies of the attitudes driving the siting process are needed to understand how these relationships evolve over time.
