Despite periods of heavy rain, thousands of domestic wells across California's Central Valley remain at severe risk of going dry.

During a historic drought, California passed the Sustainable Groundwater Management Act (SGMA) to halt the dangerous over-pumping of aquifers.

SGMA gave local water agencies up to 20 years to achieve true sustainability. In the interim, aggressive groundwater pumping has continued.

Projections show that up to 5,200 more domestic wells could fail by 2040 before the law fully takes effect and stabilizes water tables.

Large agricultural operations can afford to drill deeper wells. This systematically drains the shallow aquifers that rural households rely on.

When residential wells fail, families are often forced to rely on expensive bottled water or temporary community tanks for basic survival.

Climate change fuels weather whiplash. Prolonged, severe droughts force a heavier reliance on underground reserves that are already depleted.

Many local sustainability plans currently lack adequate protections or mitigation funds to support vulnerable communities when their drinking water disappears.

State regulators are now stepping in, rejecting inadequate local plans to force faster action and protect the human right to water.
