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.

What do we mean by "shoes waiting to drop?" We mean the trends that are already well under way — but that we can't quite see yet. These trends could overwhelm us if we don't spot them now and aggressively use our knowledge to plot our course for the future. The five "shoes" highlighted in the report are: A Talent Shake Up; Latino Education Dilemma; A Fuzzy Economic Identity; Lost Stewardship; and The Revenue Sieve.
