Short summary

To constrain water fluxes in the subsurface capable of transporting contaminants we assessed the amount of water that moves from surface to groundwater on a plateau near Los Angeles. We found that on average only 16 mm (4 %) of precipitation becomes groundwater annually. However, values vary from 0 to >1000 mm yr⁻¹ due to topography, vegetation and surface geology. The flux is not steady over the year but happens episodically at the end of the wet season or after exceptional precipitation events.
