I want to know the answer to the following question:
What aquifer is Tucson starting new wells in?
All the background I'm provided with is that "To prevent further loss of groundwater, Tucson has been involved in water conservation and groundwater preservation efforts, shifting away from its reliance on a series of Tucson area wells in favor of conservation, consumption-based pricing for residential and commercial water use, and new wells in the more sustainable Avra Valley aquifer, northwest of the city.". Is that enough to answer the question?
Answer: yes
