The Lower San Pedro Groundwater Basin (LSP) baseline groundwater quality study was conducted by the Arizona Department of Environmental Quality in 2000. Located in southeastern Arizona, this semiarid basin is drained by the San Pedro and Gila Rivers. The LSP is a rural landscape with scattered towns and two extensive copper mining and processing operations. Groundwater from three aquifers (floodplain, unconfined basin-fill, and confined basin-fill or artesian) and fractured mountain hardrock is the principle source of water supply. For this study, 63 groundwater sites were sampled for inorganic constituents. In addition, fewer sites were also sampled for Volatile Organic Compounds ...

The Upper Hassayampa groundwater basin covers approximately 787 square miles within Maricopa and Yavapai counties and is located about 60 miles northwest of Phoenix. The basin is characterized by mid-elevation mountains and had an estimated population of 10,479 in 2000. The largest population center is the Town of Wickenburg. Other communities include Congress and Groom Creek. Low-intensity livestock grazing is the predominant land use and most ranches have limited acreages of irrigated pasture to raise additional animal feed. There are no surface water diversions or impoundments besides small stock ponds within the basin. Groundwater is the only source for public ...

The Aravaipa Canyon groundwater basin covers approximately 517 square miles in southeastern Arizona within Graham and Pinal counties. Largely undeveloped, the remote basin has an estimated 135 residents and includes the community of Klondyke. Low-intensity livestock grazing is the predominant land use although there are some irrigated fields and orchards along Aravaipa Creek. Historic mining activity resulted in the creation of the Klondyke Tailings Water Quality Assurance Revolving Fund site in 1998. Groundwater is used for all domestic purposes within the basin as well as most irrigation and stock water supplies. Irrigation uses the most groundwater in the basin.

In pursuing its mandated mission to characterize groundwater quality in the state, the Arizona Department of Environmental Quality has collected samples from 1,477 sites over a 15-year period between 1995 and 2009. The sample sites consisted mainly of domestic, stock, irrigation and municipal wells and, to a lesser extent, springs used predominantly for watering stock and wildlife. Sampling activity was conducted within 35 of the state’s 51 officially designated groundwater basins and covered much of Arizona with the exception of Native American tribal lands. The data provide comprehensive and reliable information on the occurrence and concentrations of groundwater contaminants. This ...

The State And Local Arizona Documents (SALAD) collection contains documents published by the State of Arizona, its Counties, incorporated Cities or Towns, or affiliated Councils of Government; documents produced under the auspices of a state or local agency, board, commission or department, including reports made to these units; and Salt River Project, a licensed municipality. ASU is a primary collector of state publications and makes a concerted effort to acquire and catalog most materials published by state and local governmental agencies.

The ASU Digital Repository provides access to digital SALAD publications, however the ASU Libraries’ non-digitized Arizona documents can be searched through the ASU Libraries Catalog and Library One Search. For additional assistance, Ask A Government Documents Librarian.

Publications issued by the Morrison Institute for Public Programs at Arizona State University are available in the ASU Digital Repository Morrison Institute for Public Policy - Publications Archive collection.
