The purpose of this health consultation is to evaluate the air monitoring conducted by the Arizona Department of Environmental Quality at Mary McLeod Bethune School (Phoenix, AZ) and evaluate the potential impact on public health. The air monitoring data includes particulate matter and metals. The ADEQ’s primary objective of this air sampling is to provide an understanding of the hazardous air pollutants in the Phoenix area.

The W.R. Grace facility in Phoenix, Arizona, received vermiculite concentrate from the Libby, Montana, vermiculite mine. W.R. Grace Company has owned and operated the Arizona site since 1964. In 1964 W.R. Grace purchased the company that had previously occupied the site and, following the relocation of its vermiculite exfoliation furnace from Glendale, Arizona, began processing vermiculite concentrate and marketing it under the Zonolite® brand. The objective of this health consultation is to evaluate exposure pathways and potential health effects in those persons who, between 1964 and 2002, may have been exposed to Libby asbestos as a result of vermiculite concentrate processing activities and waste materials from the W.R. Grace exfoliation facility in Phoenix.

The Decision Center for a Desert City at Arizona State University—funded by the National Science Foundation since 2004—conducts research relevant to water resources and urban climate dynamics under multiple uncertainties. This report summarizes and synthesizes research findings and achievements of DCDC after almost a decade of research and science-policy interactions. Water resource decision-making is complicated by climate change and variability, population growth and economic development, diverse stakeholder interests and fragmented governance. While these factors generate various uncertainties and complexities for decision-makers, DCDC pursues research to create a more sustainable future. The DCDC contributes to water management and urban sustainability by conducting basic science and collaborating with policymakers and stakeholders to solve real-world problems. As detailed herein, DCDC research, education, and community outreach have made substantial contributions to improving water-resource governance and climate adaptation.
