Spencer, J.E., 2011, Preliminary Evaluation of Cenozoic Basins in Arizona for Carbon Dioxide Sequestration Potential. Arizona Geological Survey Open File Report, OFR-11-05, 14 p.Description
The U.S. Department of Energy (DOE), through its National Energy Technology Laboratory (NETL), established a national program to evaluate the feasibility of separating carbon dioxide (CO2) from industrial sources and pumping it underground for long-term storage or disposal. This program was established in response to concerns that CO2 emissions from fossil-fuel combustion, and from other industrial processes such as cement production from limestone, are increasing atmospheric CO2 concentration and solar-energy absorption, thereby causing global warming. Carbon dioxide removal from industrial sources and storage in geologic reservoirs is known as “geologic sequestration.” A major aspect of the DOE program is to evaluate subsurface geology to determine the potential of underground rock formations for long-term CO2 sequestration. WESTCARB (West Coast Regional Carbon Sequestration Partnership) is a consortium of seven western U.S. States and one Canadian Province that is one of seven regional North American partnerships established to evaluate technical aspects of high-volume CO2 capture and sequestration. Collaborative WESTCARB research programs have included more than 90 public agencies, private companies, and non-profit organizations. The Arizona Geological Survey began work in 2010 on WESTCARB Phase III – Arizona Geological Characterization. This report represents an initial WESTCARB assessment of CO2 storage potential in Arizona’s Cenozoic basins, and is part of Task 2 of Arizona WESTCARB Phase III (California Energy Commission Agreement Number 500-10-024). The focus of this study is Cenozoic basin volume and volume below 800m depth, with the purpose of reducing the number of basins subjected to further carbon-sequestration evaluation. Basin volume below 800m depth is important because CO2 will remain in a liquid state at pressures corresponding to rock overburden at such depths. Successful sequestration requires both adequate permeability and porosity for large-volume CO2 injection, and an impermeable cap rock that will prevent movement of CO2 to shallower depth and escape to the atmosphere. Basin stratigraphy and sediment characteristics are not the subject of this report, however, but will be evaluated for a subset of basins identified in this study that are both large and deep.Additional Links

Determining Areal Precipitation in the Basin and Range Province of Southern Arizona - Sonoita Creek BasinA linear relationship between point precipitation and elevation in conjunction with a computer four-point interpolation technique was used to simulate areal rainfall over Sonoita Creek Basin, Arizona. The simulation's sensitivity and accuracy were checked against the official isohyetal map of Arizona (Univ. of Arizona, 1965) by changing the density of the interpolation nodes. The simulation was found to be in good agreement with the official map. The average areal-rainfall was calculated by integration. Cumulative rainfall amounts were assumed to be stochastically independent from one season to another. The seasonal precipitations of forty years (1932-1972) were subdivided into five groups. to check for binomial distribution. The binomial model fits the historical data adequately. The binomial model for cumulative seasonal areal-precipitation provides one way to compute the return period. This information will be necessary for decision-makers and hydrologists to predict the area's future water balance.

Chemical quality of water in relation to water use and basin characteristics, Tucson Basin, ArizonaThe areal distribution of the chemical quality of the Tucson basin ground water has been mapped. The basin was divided into five study sections, according to the relative concentrations of the chemical ions studied, The five chemical quality sections are as follows: 1. Canada del Oro; Catalina, Tanque Verde, and Rincon Mountain foothills and extension into the northeast half of the basin low concentrations except for Tanque Verde anomaly. 2. Tucson-Benson Highway area extending from east of Vail northwest to the Santa Cruz Rivermoderately high concentrations. 3. Foothills of the Santa Rita and Sierrita Mountains extending to the Santa Cruz bottom land moderate concentrations. 4. The Santa Cruz bottom land from Arivaca to Rillito moderately high to high concentrations. 5. The Tucson Mountain foothills extending to the Santa Cruz bottom land low - moderate to moderately high cone entrations0 The water quality of these sections is correlated to the geology of the basin, according to the principles set forth in the section on the "Geochemistry of Ground Water." The effects of man's lowering of the water table are not as yet evidenced in the chemistry of the ground water In conclusion, the part of the Rillito Creek drainage basin in the northeast Tucson basin fill is found to have both the best water quality and the highest specific capacities of the entire basin. Subsurface storage and impermeable boundary limitations may restrict further development of this area, however. Artificial recharge into this aquifer, from Rillito Creek, could alleviate the quantity problems.
