Arizona’s travel and tourism industry is operating in a new landscape driven by sustained economic challenges, evolving demographics, emerging technology and shifts in consumer travel patterns. Thus the creation and importance of its 5-Year Strategic Plan is to lay the foundation upon which our agency will take the lead and assist in the continued growth and prosperity of our industry over the next five years, further contributing to the overall economic development of the state.

From May 2005 to June 2005, the Arizona Department of Environmental Quality conducted a study, Potable Well Sampling Task 4.0, to determine if the chromium and chromium VI plume due to the discharge of the Pacific Gas and Electronic Topock Compressor Station has migrated under the Colorado River and impacted water supplies in Arizona. The ADEQ investigated the total chromium and hexavalent chromium (chromium VI) concentrations in (1) public water supply wells, (2) combined industrial and domestic water supply wells, and (3) private domestic water supply wells at Topock and Golden Shores, Arizona. The communities of Topock and Golden Shores have expressed their concerns regarding the findings. Thus, the ADEQ requested the Arizona Department of Health Services to evaluate the potential health effects of exposure to well water contaminated with chromium.
