To evaluate whether VOCs are migrating out of the landfills into the vadose zone, a soil vapor survey of the soil beneath the landfill bases was performed. Permanent vapor monitoring probes were installed and then sampled twice for VOCs. Groundwater beneath the landfills has been impactd by VOCs, namely TCE, DCE, and toluene.

This Additional Site Characterization Work Plan presents a strategy for collecting site characterization information at the closed Maricopa County Cave Creek Landfill to support ongoing remedial action planning for trichloroethene-impacted groundwater underlying the site. The Work Plan supplements previous remedial investigation work plans prepared to characterize the nature and extent of site contamination.

The Decision Center for a Desert City at Arizona State University was established in 2004 with funding from the National Science Foundation to advance the scientific understanding of environmental decision making under uncertainty. With additional funding awarded by NSF in 2010, "DCDC II" has expanded its already extensive research agenda, engaged the policy-making community, and built stronger ties between scientific knowledge and decision making enterprises. New DCDC research has developed fundamental knowledge about decision making under uncertainty from three interdisciplinary perspectives: climate impacts, urban dynamics, and adaptation decisions. Simulation modeling and boundary organization studies cut across these themes and are a core component of DCDC activities.

DCDC is focused on developing, implementing, and studying an interdisciplinary decision-support process for environmental decision making based on principles derived from social science research. Through an integrated approach to research, education, and community and institutional outreach, DCDC is training a new generation of scientists who can work successfully at the boundaries of science and policy. Broader impacts are realized as research informs innovative solutions to society’s pressing environmental challenges. To accomplish these goals, DCDC has built a dynamic bridge between ASU and local, regional, and national policy communities to foster local to-global solutions for water sustainability and urban climate adaptation.

The South Mountain neighborhood is located in the southern part of the City of Phoenix in Maricopa County. The three zip codes of 85040, 85041 and 85042 comprise the bulk of the neighborhood and serve as the target area boundary for this report. South Mountain is a distressed community, with significant need and limited resources. It is an area that differs from most of the city, with a pre- dominantly economically disadvantaged Latino and African-American population. As part of Maricopa County’s efforts to identify the needs, the gaps in services and resources, and to use data to inform the County about making effective and meaningful policy changes, this report uses data collected as part of the ongoing AARIN project and economic measures derived from U.S. Census data to help examine and potentially guide restoration efforts in South Mountain.
