A majority of the work performed by ADEQ's Nonpoint Source Program is funded by Clean Water Act grants, awarded by the U.S. Environmental Protection Agency which requires States to report annually on progress in meeting the schedule of milestones contained in their nonpoint source management plans, and report reductions in nonpoint source pollutant loadings and improvement in water quality resulting from program implementation.

The Arizona Department of Transportation, the Arizona Game & Fish Department and the Arizona State Parks Board are required to conduct a study every three years on watercraft fuel consumption and recreational watercraft usage. The fuel consumption data is collected to determine the allocation of motor vehicle fuel tax to the State Lake Improvement Fund. The information on recreational watercraft usage patterns on Arizona’s lakes and rivers is necessary, in part, to determine the distribution of SLIF funds to applicants.

The Chandler Airpark area encompasses nine square miles surrounding the Chandler Municipal Airport. The area plan provides the City of Chandler with a document that will strategically guide future development in and around the existing airport. The two major goals of this plan are the protection of the Municipal Airport from residential encroachment and the aggressive economic development of the Airpark area.

The City of Chandler developed the South Arizona Avenue Entry Corridor Study in 2006, setting forth a vision for the development of the corridor between Dr. A.J. Chandler Park and the new SanTan Freeway, ¾ mile to the south. Between downtown and the freeway is the corridor that the City intends to see redeveloped, with mixed residential and commercial uses to create a dynamic new “front door” for Chandler. The purpose of these design guidelines is to guide zoning requests within the South Arizona Avenue Corridor to achieve the objectives of the Chandler General Plan. The overall goal of these objectives is to implement the vision for South Arizona Avenue. The guidelines address the major design aspects of new office, retail and residential buildings in the corridor. Design Guidelines are not building or streetscape designs; they provide design direction so that each project’s architectural design will reinforce the City’s strategic intentions as this important area of the city responds to its new role as Chandler’s “front door.” These guidelines also identify streetscape design principles for South Arizona Avenue with the objective of coordinating public and private design in the Corridor.

This study involved the review of 417 ADEQ LUST site files and compilation of relevant data from 323 of these sites into an electronic database. It also involved the collection and analysis of over 700 supplemental groundwater samples, the assessment of aquifer flow properties from 32 wells at 11 sites, and more detailed characterization at six LUST sites representative of a range of conditions at AZ LUST facilities. In addition, over 300 groundwater level measurements were performed and 175 monitoring wells were re-surveyed in order to assess errors in standard practice and their impact on groundwater flow direction determination. An empirical analysis of groundwater impacts at AZ LUST sites was conducted using these data sets, with emphasis on identifying relationships between site conditions (e.g., geology, depth-to-groundwater, etc.) and groundwater impacts. Finally, a combined theoretical-spatial (GIS) analysis was performed to identify LUST scenarios posing the greatest threats to use of groundwater resources.

In March 2004, the U.S. Environmental Protection Agency requested information on efforts to monitor and protect children from exposure to lead in drinking water at schools. The Arizona Department of Health Services reviewed the state lead poisoning registry, and analyzed drinking water samples from 45 randomly selected schools. The Office of Environmental Health provided this consultation to help document our findings and supplement our response to the EPA. This work was also undertaken to help provide useful information should hazardous waste sites be discovered in the future near these schools. We also wanted to apply the ATSDR health assessment process in support of state and federal efforts to protect the health of children.
