Reports on the development of a reconnaissance level numerical groundwater model of the Davidson Canyon and Cienega Creek watersheds. Includes recommendations for data that must be collected prior to completing environmental analyses for the proposed project.
The Augusta Resources Corporation proposes to construct the Rosemont Mine project in the northern Santa Rita Mountains. This report is a reconnaissance analysis of the conceptual flow and water balance in the area. The conceptual flow model for the area is based on topography, geology and precipitation and identifies the likely flow paths in the watershed and aquifer system. The water balance includes estimates of recharge to and groundwater flow from the area; there is no evapotranspiration discharge from the regional groundwater.
An introduction to the impact of conservation alternatives on air quality which will be integrated into the land use and conservation plans. The air quality study is summarized in this memorandum.
The study generally confirms the trends and impacts identified in the February 2001 study "Air Quality in Pima County," and suggests two types of strategies for maintaining air quality and ensuring compliance with federal air quality standards. Potential funding sources and future legislative considerations are briefly discussed.
