In September 2005, some concerned Walker residents contacted the Arizona Department of Health Services in regards to the quality of groundwater in the area. The residents petitioned ADHS to perform well water tests to determine the character of the water, and whether there is any potential health risk associated with consuming or using the water. In response to the concerned community members and in agreement with the Agency for Toxic Substances and Disease Registry, ADHS collected water samples from the site and completed a health consultation. This health consultation evaluates if the levels of lead and other metals in the private wells in Walker area pose any adverse health effects.

Previous studies at Lake Havasu and Lake Powell, combined with other national data indicate that carbon monoxide poisoning from recreational watercraft can create a significant health hazard. The current study was designed not to repeat the 2003 study. Instead, it was designed to explore the potential health effects of carbon monoxide under the conditions of Humbug Cove. Humbug Cove is known for congregating idling boats, higher frequency of alcohol consumption, and being a location that was secluded and sheltered from breezes or wind.

The Miller Road Treatment Facility was built by the North Indian Bend Wash Participating Companies to treat groundwater in order to reduce the levels of volatile organic compounds that have contaminated the aquifers. The facility was brought on-line in March 1997, and ownership was transferred to AAWC in December 1997. The facility processes the groundwater to remove the VOCs. Between January 15–17, 2008 trichloroethylene (TCE) was detected in the Paradise Valley Water System. Arizona American Water Company, who own and operate the Paradise Valley system, contacted the Arizona Department of Health Services and requested assistance in determining possible health risks from exposures related to this incidence. In response, the Arizona Department of Health Services reviewed existing data and performed a health consultation to evaluate the possibility of adverse health effects associated with this event.

The Arizona Department of Health Services received a request for a Health Consultation from the City of Litchfield Park, dated March 5, 2007. The nature of the request was for ADHS to determine if there was a risk to public health from eating fish taken from Tierra Verde Lake. The City sponsors an annual fishing derby and believed that some citizens were eating the fish they caught. The City tested their lake water and for the very first time, measurable amounts of perchlorates were detected. The probable source for the perchlorates was thought to be from a groundwater, contaminant plume originating from the Phoenix Goodyear Airport Superfund Site.

Local residents expressed their concerns regarding the tailings from the Iron King Mine and Humboldt Smelter at Dewey-Humboldt, AZ. The purpose of this health consultation is to evaluate the available water and soil sampling results to determine if the detected metal levels pose adverse health effects when residents come into contact with the water or soil. In 2008, EPA initiated the field investigation portion of the Remedial Investigation and Feasibility Study for the Site. The primary objectives of the RI/FS are to determine the nature and extent of contamination and to gather sufficient information so that EPA can select a long-term remedy that eliminates, reduces, or controls risks to human health. The investigation included the collection of airborne particulates, groundwater, surface water, surface soil, subsurface soil, and sediment data across the entire Site. Data from the RI/FS was not available at the time the health consultation was prepared and thus it was not incorporated into this health consultation.

The Arizona Department of Health Services reviewed existing data and performed a health consultation to evaluate the potentially adverse health effects due to VOCs created by air emissions from the Miller Road Treatment Facility. Prior to the existence of our current environmental regulations, local industries improperly disposed of organic solvents directly onto the ground or into dry wells. This subsequently contaminated all three levels of the aquifer.

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.

This report evaluates the potential exposure pathways associated with vermiculite concentrate processing activities at the Ari-Zonolite facility. The site is located in the near downtown area of Glendale, approximately ½ mile from the city hall, downtown shops, and other buildings. The former Ari-Zonolite facility received vermiculite from the Libby, Montana, mine. From 1951 to 1964, the site was leased the site to the Ari-Zonolite Company. Following the removal of the vermiculite concentrate processing equipment in 1964, several businesses have occupied the site. None of these businesses were involved in vermiculite processing activities. The last occupant of the former vermiculite processing building was an automotive restoration business, which vacated the site in 2002.

State trust lands are among the greatest public assets in Arizona’s portfolio. Set aside at statehood, the Arizona State Land Department manages more than 9 million acres of trust lands on behalf of 14 beneficiaries. The largest of which by far is Arizona Public Education K through 12.The mission of the Land Department is to maximize revenues from these trust lands. In FY 2005, state trust lands generated $115 million for all beneficiaries, of which $101 million was designated to support public K-12 schools.These amounts are increasing rapidly as more state trust land becomes attractive for development in Arizona’s urban areas.

The parcel discussed in this report, “Superstition Vistas,” stands out as the jewel among Arizona’s trust lands. Not only is it situated in the path of metro Phoenix growth, but it also borders thousands of acres of public land managed by the Tonto National Forest and U.S. Bureau of Land Management. Estimates of its total value run well into the billions of dollars.

"The Treasure of the Superstitions" sets the stage for a continuing dialogue about the potential for Superstition Vistas, and indeed, all of Arizona’s trust lands. We look forward to listening to and working with our beneficiaries, citizens, counties, municipalities, real estate businesses, and other interested parties to make the most of Arizona’s “treasure.”

The March 2006 responses to a statewide representative telephone survey show that a majority of Arizonans see science and technology research as a source of high-paying jobs and are every bit as interested in science and technology as leaders are. Arizonans "get" the benefits of a science and technology-based future and the power of science and technology to spawn desirable employment opportunities. Some cautions emerge as well, but even so, most Arizonans look to science and technology as integral to a bright economic future.
