From the Environmental Defense Fund:
One of the biggest challenges to implementing California’s Sustainable Groundwater Management Act hovers around this two-part question:
Who gets to pump groundwater and how much do they get to pump? Or, put another way, who must cut their groundwater use and by how much?
As local groundwater agencies try to answer this difficult question on how to develop allocations, they face one major constraint: They can’t change groundwater rights.
Consequently, the path forward for many groundwater agencies is riddled with legal complexities and questions around equity that shouldn’t be ignored.
