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 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.

In a rapidly growing desert metropolis such as Phoenix, the question of which water conservation measures and factors actually save water and which do not is an obviously important one. The water-related decisions made today and in the years to come will have lasting impact on the future of this area, including upon its sustainability. Estimates from the City of Phoenix suggest that, in non-SRP-areas, water demand will exceed water supply by the year 2025--absent droughts or intervention.

This report documents and analyzes the results of a multivariate regression analysis designed to estimate the effects on residential, single-family water consumption of a host of factors, particularly water conservation policies.

Community policing — “a collaboration between the police and the community that identifies and solves community problems” — is not new to the City of Phoenix Police Department. They adopted this philosophy in the early 1990s. In 1995, they sought to expand community policing in Phoenix by applying for, and receiving, a $1.5 million grant from the U.S. Department of Justice to implement the Comprehensive Communities Program (CCP) — a project designed to implement community policing in an urban neighborhood and demonstrate its potential.

This briefing paper summarizes the measures used in the CCP evaluation and briefly examines whether
results answer the question: Is community policing effective? More specifically, it focuses on whether the Comprehensive Communities Program resulted in outcomes desired by neighborhood residents. That is—Did crime go down? Do residents feel more safe? Does a formal partnership between the police and a neighborhood make a difference?
