Despite California's reputation as an environmental policy leader, its regulation of groundwater extraction has long been among the weakest in the nation. That changed Tuesday, when California Governor Jerry Brown signed a package of three bills designed to regulate the pumping of water from underground aquifers.
While many observers say the rules are too little and too late to protect the state's rapidly depleting aquifers, the new laws are still a major shift in a long-deadlocked political battle.
"They don't solve all our problems, but they're a critical step in the right direction," says Jay Famiglietti, a hydrologist at the University of California, Irvine.
