No, this isn't just about California, but it's drought-ridden California in the headlines currently
(Talking about the US; No I didn't forget about the existence of Australia), what with the recent headlines about the state only having a year's worth of water-supply remaining. And what with the scientists telling us that historically the nineteenth and twentieth centuries actually represented an
abnormally wet period for California, the news isn't likely to get better any time soon. Still, always helps to get,
a little perspective...
By now, the impacts of California’s unchecked groundwater pumping are well-known: the dropping water levels, dried-up wells and slowly sinking farmland in parts of the Central Valley.
But another consequence gets less attention, one measured not by acre-feet or gallons-per-minute but the long march of time.
As California farms and cities drill deeper for groundwater in an era of drought and climate change, they no longer are tapping reserves that percolated into the soil over recent centuries. They are pumping water that fell to Earth during a much wetter climatic regime – the ice age.
Such water is not just old. It’s prehistoric. It is older than the earliest pyramids on the Nile, older than the world’s oldest tree, the bristlecone pine. It was swirling down rivers and streams 15,000 to 20,000 years ago when humans were crossing the Bering Strait from Asia.

“What I see going on is a future disaster. You are removing water that’s been there a long, long time. And it will probably take a long time to replace it. We are mining water that cannot be readily replaced,” said Vance Kennedy, a 91-year-old retired research hydrologist in the Central Valley.
