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.

In the fall of 1995, the City of Phoenix Police Department convened a special group of people known to be deeply involved with the social and personal aspects of domestic violence. This group, which came to be called the Phoenix Police Department's Joint Task Force on Domestic Violence, consisted of police and criminal justice personnel, social service and health care providers, and a number of interested community members. Task Force members soon began earnest discussions on how best to reduce the incidence of domestic violence-a crime that is, sadly, the number one call for police service in the City of Phoenix.
