During the hot summer months of 2014, East Porterville, Calif., became a poster child for vulnerable drinking water. Hundreds of shallow wells in this unincorporated Tulare County community ran dry in the midst of statewide drought. Some families had to wait years to have running water again, when their homes were finally connected to the city of Porterville’s municipal water supply. While East Porterville’s experience made headlines around the country, the serious drinking-water problems facing other communities across California are just beginning to receive much-needed attention.
