Groundwater deeper than 500 m contributes less than 0.1% of global river discharge

At depths of over 500 m, deep groundwater has long residence times and likely contributes less than 0.1% to global streamflow and only sporadically connects with the surface terrestrial water cycle on geological timescales, according to estimates derived from the chloride mass balance approach.
