Groundwater pollution may be an overlooked aspect of Arizona water issues
You can’t see it, but how we live impacts it and plays a vital role in almost everything that happens in Arizona. Groundwater is located deep beneath the surface and stored in aquifers, which are porous rock that contain or transport water. About 40% of the state’s water supply is underground, with that number likely to increase due to reductions in available water from the Colorado River. An ongoing concern is what would happen if the valuable resource got contaminated.
