The Arizona Department of Health Services (ADHS) has been investigating trichioroethylene (TCE) and related compounds in Arizona groundwater since the solvent was first found in the Tucson International Airport area last spring. TCE is widely used in electronics and metal plating as well as furniture stripping, dry cleaning, and other activities. It can be toxic and has been found to cause cancer in mice.

American Indian lands comprise approximately 52 million acres in more than 26 states. Many reservations have land and water resources that have potential for agricultural development. Three land and water management alternatives for reservation farm development are discussed in a report by the University of Arizona's Laboratory of Native Development, Systems Analysis and Applied Technology (NAD SAT).

The City of Tucson is supporting a program to address water problems in the greater Tucson area. A portion of this program, administered by the University of Arizona's Office of Arid Lands Studies, is to study residential water use and to design a practical, water-efficient demonstration house.

The University of Arizona has been granted funds by the Arizona State Legislature for water-related research, instruction and information services The four-part program will be conducted by the colleges of Agriculture Engineering and the Faculty of Science.

In April 1984 Arizona's Department of Water Resources (ADWR) promulgated the first management plans for the Tucson, Phoenix and Prescott Active Management Areas (AMAs) (see summaries Arizona Water Resources News Bulletin, 84-2 Summer 1984). Public hearings on the proposed plans were held in June. Based on the testimony and evidence presented at these hearings, ADWR has released the following modifications to the proposed management plans.

Welcome to the premier issue of Arizona Water Resource. AWR is produced by the Arizona Water Resources Research Center at the University of Arizona. Representatives from various water organizations within the state, however, assisted in its planning and development. AWR represents a group effort at identifying a publication need within the state, and then developing a newsletter to respond to that recognized need.

In an effort to promote use of Arizona's CAP water entitlement, the Central Arizona Conservation District approved an expenditure to develop in lieu recharge projects. CAWCD has since received nine requests to participate in indirect recharge projects, with three obtaining all necessary permits and agreements to begin operations. They are the Central Arizona Irrigation and Drainage District, the Maricopa- Stanfield Irrigation and Drainage District, and the Roosevelt Water Conservation Recharge Projects.

The Arizona Department of Water Resources (DWR) mailed more than 570,000 certified letters to property owners in the Lower Gila River Watershed The certified letters contained a court summons regarding the Gila River General Adjudication, a proceeding in the Superior Court in Maricopa County to establish the extent and priority of all claims to water of the Gila River This was the largest certified mailing ever undertaken in Arizona

One of the most significant environmental events to occur in Arizona over the last several years is the enactment of the new state Environmental Quality Act The law, which became effective on August 13, 1986, emerged after several years of vigorous debate and conflict among the state's myriad interests, and represents a consensus achieved at the urging of then Governor Bruce Babbitt.

The Governor's CAP Task Force has released a report that is as noteworthy for what it fails to recommend as for what it does (see accompanying article). The task force declined to call for any major new taxes to bail out irrigation districts so they could continue to use large portions of the state's Colorado River allocation.
