"The purpose of this study was to update knowledge of the groundwater conditions in Paradise Valley. This was accomplished by (1) collecting and studying current basic data and comparing these data and previously collected data to determine changes in water levels and production rates of wells as related to development; (2) reconnaissance geologic mapping; and (3) analyzing the changes in the chemical quality of the water"--Pages 2-4.
