Good visibility is important to the enjoyment of national parks and scenic areas. Across the country, regional haze has decreased the visual range from 140 miles to 35-90 miles in the West, and from 90 miles to 15 -25 miles in the East. Regional haze is air pollution that is transported long distances, causing reduced visibility in national parks and wilderness areas.

Water plays a key role in industrial production. Today, with increasing demand for water resources and uncertainty about the amount and quality of supply, the competition for water resources is being felt across all sectors of society. Awareness of the ways water-related risks can disrupt business has also increased. Although the cost and price of water varies tremendously across the United States, corporations are increasingly assessing and reporting their water use and improving water process efficiency. In addition, companies are seeking economic and technological innovations.

The purpose of this Site Characterization Report is to provide a summary of existing relevant environmental data to characterize smelter affected soil at the West Plant Site, and to evaluate that data for use in the development of human health risk-based site-specific soil remediation standards (SSSRLs) for the West Plant Site.

The Pinal County Comprehensive Plan is the landmark document that will serve to steer the County on a positive course of action to manage growth, preserve the quality of life, and promote sustainability.

The Census Bureau releases two reports every year that describe who is poor in the United States. The first report calculates the nation’s official poverty measure based on cash resources. The second is known as the supplemental poverty measure (SPM) and takes account of cash resources and noncash benefits from government programs aimed at low income families.

This technical memorandum has been prepared to summarize results of drilling, construction, and testing at hydrologic test wells HRES-16, HRES-17, and HRES-18. The wells were installed to characterize hydrogeologic conditions in the Apache Leap Tuff (ALT) on the east side of Devils Canyon near the JI Ranch Fault. HRES- 16 is a larger diameter well (nominal 8-inch) that was completed to provide a location for longterm aquifer testing in the ALT aquifer. Monitoring data obtained from HRES-16, HRES-17, and HRES-18 have been incorporated into the RCM hydrologic monitoring program.
