Despite a recognized need for additional waste disposal capacity in ma
ny communities, public concern over siting new facilities is at an all
time high. There exists a substantial literature relating Not In My B
ack Yard (NIMBY) reactions to siting proposals. However, much less is
known about individual and community level impacts around existing fac
ilities. This paper presents the results of a comparative analysis of
psychosocial impacts (i.e. concern and distress) in two Canadian popul
ations living in close proximity to municipal solid waste incinerators
. Results show relatively low levels of impacts reported in both incin
erator communities, contrary to what might be anticipated given the NI
MBY literature. Determinants of impacts in the two communities highlig
ht the need to recognize the role of community context in attempts to
understand or mitigate impacts. Comparative analyses substantiate this
finding, but also point to areas of similarity between the two commun
ities studied. These and related findings have to date been incorporat
ed into waste management decisions in local areas. However, additional
comparative, as well as longitudinal, research is needed to fully und
erstand how individuals and communities respond to waste facility siti
ngs, and how these responses change over time.
