Makes up 23 of Earths freshwater 12 Shallow we can reach 11 Deep out of our reach Underground Layers When precipitation occurs water often seeps down into the soil and trickles down in between particles of soil and through cracks and spaces in layers of rock . Use of brackish groundwater could supplement or in some places replace the use of freshwater sources and enhance our Nations water security However a better understanding of the location and charac ter of brackish groundwater is needed to expand dev Hydraulic Head.
