Air Concentrations Of Volatile Compounds Near Oil And Gas Production: A Community-Based Exploratory Study, Gregg P. Macey
Air Concentrations Of Volatile Compounds Near Oil And Gas Production: A Community-Based Exploratory Study, Gregg P. Macey
Gregg P. Macey
Background: Horizontal drilling, hydraulic fracturing, and other drilling and well stimulation technologies are now used widely in the United States and increasingly in other countries. They enable increases in oil and gas production, but there has been inadequate attention to human health impacts. Air quality near oil and gas operations is an underexplored human health concern for five reasons: (1) prior focus on threats to water quality; (2) an evolving understanding of contributions of certain oil and gas production processes to air quality; (3) limited state air quality monitoring networks; (4) significant variability in air emissions and concentrations; and (5) …
Community Environmental Policing, Gregg P. Macey
Community Environmental Policing, Gregg P. Macey
Gregg P. Macey
This paper evaluates a new form of public participation in environmental monitoring and regulation advanced through local bucket brigades, which allow community members to sample air emissions near industrial facilities. These brigades represent a new form of community environmental policing, in which residents participate in collecting, analyzing, and deploying environmental information, and more importantly, in an array of public policy dialogues. Use of this sampling technology has had marked effects on local residents' perceptions and participation in emergency response and citizens' right-to-know. However, when viewed through the lens of the more developed literature on community policing, the bucket brigades are …
An Investigation Of Environmental Racism Claims: Testing Environmental Management Approaches With A Geographic Information System, Gregg P. Macey
An Investigation Of Environmental Racism Claims: Testing Environmental Management Approaches With A Geographic Information System, Gregg P. Macey
Gregg P. Macey
The purpose of this research was to explore the concept of an environmental racism claim through the use of several environmental management tools. The EPA's Toxics Release Inventory, Cumulative Exposure Project, and the Los Angeles County Department of Health Services' Hot Zone Census Tract Assessment were combined with racial and socioeconomic data to test claims that minorities in South Central Los Angeles are disproportionately exposed to environmental lead. Multivariate analysis indicated that race is strongly associated with the number of cases of elevated lead levels in South Central, irrespective of poverty status. Proximity to point sources, a common focal point …
