[During the last drought], small rural communities reliant on shallow wells — many of them communities of color — were among the most affected. More than 2,600 households reported losing access to water because their wells went dry between 2012–16. (That number is likely an undercount as reporting was voluntary.) Much has changed however since the 2012–16 drought. Drought reporting systems such as MyDryWaterSupply are available today, and better data on domestic well depths and locations, as well as groundwater levels, aid our understanding of drought risk.
