Stream flow disappearance due to groundwater pumping, floodplain development, and habitat loss due to erosion have significantly altered the biologically rich and diverse riparian corridors of eastern Pima County. Today, there are new opportunities to recreate our watercourses as a gathering place for people and wildlife.
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.
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.
