A Perspective on the Historical Analysis of Race and Treatment Storage and Disposal Facilities in the United States

Studies of environmental injustice have been intensely scrutinized by social science researchers since the publication of the United Church of Christ's Commission for Racial Justice report entitled Toxic Wastes and Race in the United States in 1987. Importantly, there has been an emphasis on analysing longitudinal data to answer the question 'which came first, people or pollution?' In addition, determining where environmental hazards are located and how demographics around those hazards are estimated has become central to any empirical enquiry on the topic. This new letter by Mohai and Saha (2015 Environ. Res. Lett. 10 115008) adds to our emerging understanding of environmental justice by analysing the distribution of Treatment, Storage and Disposal Facilities across the United States to determine why they are concentrated in non-white and low income neighbourhoods. The researchers clearly demonstrate how longitudinal analysis and advances in geographic information system methodology can help address meaningful social questions about environmental inequality that are central to environmental policy and practice
