Ground Water and Land Subsidence – A Pending Crisis?
Californians have seen a concerning image: a person standing next to a telephone pole with signs labeled with years, illustrating the effects of land subsidence.
The pole bears signs reading "1962" at the top, "1970" several feet lower, and further down, signs for "2015", "2019", "2021", and "2025" at the bottom, each representing the ground level for that year.
This iconic photo demonstrates the severe impact of subsidence on the valley, resulting from excessive water pumping without replenishment.
The signs on the pole show how much the ground has sunk over the years.
The image highlights the pressing issue of land subsidence and its relation to groundwater depletion.
