The SDCP recognizes the important links between groundwater, streamflow, and vegetation that still exist along some streams and springs in Pima County. Unfortunately, depletion of aquifers has altered streamflow and associated groundwater-dependent vegetation along the Santa Cruz River and other streams. The main purpose of this report is to establish priorities for potential expansion of Pima County's existing aquifer monitoring for groundwater-dependent ecosystems.

Provides a review of eight monitoring efforts in southern Arizona to highlight their accomplishments and to critique their efficacy and overview of important attributes of a monitoring program. This review of projects and successful attributes will provide an assessment framework to better guide the development of the Pima County Ecological Monitoring Program.

Provides the data and analysis necessary for the County's Environmental Impact Statement as it relates to the potential impact that issuing a permit could have on low income or minority people in Pima County. The study goes beyond this narrow assessment too, and discusses the cultural, social and fiscal issues related to the larger topic of environmental justice.
