The substantial health, social, and economic costs borne by rural, low
-income, and minority communities because of their differential exposu
re to environmental hazards is being increasingly acknowledged. For de
cades, these groups have been the the victims of a variety of activiti
es and policies that have placed them at a substantial risk to their h
ealth and quality of life. Recently, many of these policies have come
under increasing criticism by an emerging environmental justice moveme
nt-a movement that promises to be one of the strongest forces for envi
ronmental reform to appear in recent years. It is argued that question
s of justice and equity in environmental decision making are deserving
of increased attention by the research community. A number of questio
ns that can guide such a research agenda are identified.
