What if we told you that more than 95% of the rain and snow that falls in Arizona never reaches our groundwater?
That surprising finding is at the heart of new research discussed by Katharine Jacobs, former director of the Center for Climate Adaptation Science and Solutions at AIR, on KJZZ Phoenix. The Arizona Tri-University Recharge and Water Reliability Project is exploring how Arizona can better capture precipitation before it's lost to evapotranspiration and recharge aquifers that communities depend on.
Rather than letting water evaporate or run off, researchers are identifying practical ways to help more of it soak into the ground, from smarter urban stormwater management to improving recharge in forested landscapes.
As Arizona faces hotter temperatures and increasing water challenges, research like this is helping shape solutions for a more resilient future.
