Did you know the USGS has been studying groundwater since we were founded? USGS first measured the groundwater level at the well in this photo in 1918, over one hundred years ago! How often water levels are measured at a site in the USGS groundwater monitoring networks varies, depending on the scientific purpose of the measurement.
