Short summary
Land subsidence has been identified as a potential issue in San Diego, California, USA. The USGS, along with local agencies, undertook a cooperative study to better understand how the local aquifer responds to changes in groundwater pumping using satellite-based remote sensing techniques. Analysis indicates that a reduction in pumping resulted in land-surface uplift, and an increase in pumping resulted in subsidence. Results will help water manager effectively maintain water supplies.
