Groundwater levels above NGVD 1929 for the period of July 6, 2018 to October 30, 2019 were revised on March 30, 2020.  Water-level elevation data were originally appended with the incorrect time zone selected causing the water-level elevation record to be shifted by 4+ hours.  Data were reloaded for the period to correct the error.
