Some of California’s aquifers, including large basins in the San Gabriel and San Fernando valleys, are contaminated with chemicals.
One of the greatest dangers is nitrates that leach from fertilizers, manure and sewage. Pesticides, oil waste, industrial solvents and other contaminants also pollute groundwater. The Community Water Center, a social justice group, estimated that more than one million state residents are exposed to unsafe drinking water each year.
In 2012 Brown signed into law AB 685, the Human Right to Water Act, which aims to bring safe, clean water to all Californians. Prop 1, a $7.5 billion bond passed by voters in 2014, allocated $520 million for clean, safe and reliable drinking water. Newsom signed SB 200, setting aside $130 million per year for a decade.
