An oversight hearing on the Central Arizona Project (CAP) Tucson Aqueduct was held March 13 in Tucson by a subcommittee of the U.S. House of Representatives Committee on Interior and Insular Affairs, the Subcommittee on Water and Power Resources. Testimony was received concerning the size and the terminus location of the aqueduct and on the Papago Indian water entitlement. About 30 witnesses were heard, including Governor Bruce Babbitt, U.S. Senator Dennis DeConcini, Tucson Mayor Lew Murphy, and a broad range of water users in the area.

The Surface Mining Control and Reclamation Act of 1977 requires an inventory of hazardous mining areas within each state and periodic monitoring of active mines. In 1979 the Office of Surface Mining contracted with the University of Arizona Applied Remote Sensing Program (ARSPL Office of Arid Lands Studies, and the Mining and Geological Engineering Department for an evaluation of Landsat as a means for meeting these requirements. The objectives were to inventory mining activity in Arizona, where there are 41 active surface mines, and develop a mine monitoring system, delineate mined lands with high hazard potentials, and develop a training package for state agency personnel.

The Arizona Department of Health Services (ADHS) is developing an Underground Injection Control (UIC) program to regulate the underground disposal of wastes via injection wells. The program will be initiated in February, 1982, after promulgation of the state UIC regulations.

Groundwater withdrawals in Arizona in 1978 and 1979 were, with one exception, the smallest in over twenty-five years. According to a recent U.S. Geological Survey report prepared in cooperation with the Arizona Department of Water Resources, about 4.0 million acrefeet of groundwater was withdrawn in Arizona in 1979, which is about 200,000 acre-feet less than the amount withdrawn in 1978. The withdrawals in 1978 and 1979 are the smallest since the mid-1950's, with the exception of 1966.

A design for developing a comprehensive groundwater quality management program was outlined recently in an article* by Raymond G. Giese, hydrologist with the Ground Water Protection Section of the U.S. Environmental Protection Agency (EPA). His design "represents a compilation of ideas from states that are currently developing groundwater programs."

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.
