Does water use restrict the location of industrial air polluters

TLDR: In this article, the authors examined water use in industrial production as a cause of geographical clustering of major air polluting industries and found that the majority of industrial air pollutants are emitted within urban areas which are on water bodies with high and consistent volumes of water available.

Abstract: The paper examines water use in industrial production as a cause of geographical clustering of major air polluting industries. It shows that the majority of particulate and sulfur oxide emissions in the State of Illinois is emitted by industries using more than five billion liters of water per establishment per year. It also shows that the majority of industrial air pollutants is emitted within urban areas which are on water bodies with high and consistent volumes of water available. These and other results cited in the paper imply that any policy directly or indirectly promoting geographic dispersal as a means of reducing air pollution concentrations and population exposure rates is likely to be limited in effectiveness. It is suggested that such a policy can be effective only if at least one of two specified conditions is met. However, these conditions do not, by themselves, insure the success of such a policy. Finally, it is observed that the conjunction of air pollution with industrial water use indicates that much closer attention is needed to the relationship between air pollution and water pollution policies.
