The Water Infrastructure Finance Authority of Arizona is an independent entity authorized to finance the construction, rehabilitation and/or improvement of drinking water, waste water, waste water reclamation, and other water quality facilities/projects. As a “Bond Bank”, WIFA is authorized to issue water quality bonds on behalf of communities for basic water infrastructure. Generally, WIFA offers borrowers below market interest rates on loans for 100% of eligible project costs.

The Water Infrastructure Finance Authority of Arizona implements three types of technical assistance:
1. Project Technical Assistance – Planning and Design Assistance Grants assist an individual drinking water or wastewater system to conceive, plan, design, or develop an infrastructure project.
2. Policy Technical Assistance – Policy TA includes studies, surveys and other types of reports that provide benefit to a range of drinking water and wastewater systems statewide.
3. Operational Technical Assistance – The Arizona Department of Environmental Quality manages this program to provide assistance to individual drinking water and wastewater systems to improve facility operations.

The Drinking Water State Revolving Fund IUP describes WIFA’s plan to utilize various sources of funds to finance drinking water infrastructure and support related program activities during the State FY funding cycle from July 1 through June 30. This plan is a required element of the grant application documentation to obtain the grant award. Arizona herewith submits its IUP for the funds available to Arizona for the purposes of continuing the development, implementation and administration of the DWSRF program in Arizona.

The Intended Use Plan describes WIFA’s plan to utilize various sources of funds to finance clean water infrastructure and support related activities during the State FY funding cycle from July 1 through June 30. This plan is a required element of the grant application documentation to obtain the grant award for the purposes of continuing the development, implementation and administration of the Clean Water State Revolving Fund program in Arizona.

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.

The objective of this assessment is to evaluate whether a public health hazard exists as a result of environmental exposures in Hayden and Winkelman, Arizona, located near a smelter operated by ASARCO, Inc. Some of the residents of these towns have expressed concerns that metals from smelter emissions over the years have been causing health problems. This report uses environmental data collected from water, soil, and air in the Hayden and Winkelman area to estimate environmental exposures. The study also evaluates available health outcome data from previous epidemiological and biological-monitoring studies conducted in the area. The report concludes that exposure to sulfur dioxide occasionally poses a short-term public health hazard to sensitive asthmatics. These episodes of higher levels of sulfur dioxide occur infrequently. They do not appear to pose a health hazard to persons without sensitive airways or asthma. Other environmental exposures do not appear to pose a public health hazard.

In March 2004, a resident of Cornville contacted the Arizona Department of Environmental Quality to request information on arsenic in drinking water. The resident collected six well water samples from their own well and neighbors’ wells and submitted them to a private laboratory for arsenic analysis. The analyses detected arsenic ranging from 15 to 952 μg/L. ADEQ and the community members asked the Arizona Department of Health Services to provide health information about using the water. Initial conversations with the well owner and other community members revealed that many people had concerns about potential health effects from arsenic exposure.

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 September 1999, the U.S. Environmental Protection Agency contacted the Arizona Department of Health Services, Office of Environmental Health, concerning potential contamination of private drinking water wells along Lynx Creek in the Walker, Arizona, mining district. Historical mining activities in the area might have resulted in contamination of groundwater by acid mine runoff as well as metals from extraction processes. EPA and ADHS determined the historical mining activity had caused environmental damage and the potential for adverse human health impacts. ADHS initiated a private well sampling program to determine if the mining activity has had an adverse impact on the quality of water from these wells. Several area residents have expressed concerns about their water quality. The objective of this public health consultation is to evaluate the potential for health effects from exposure to contaminants in private drinking water wells in the Walker, Arizona area.
