Seasonal recharge components in an urban/agricultural mountain front aquifer system using noble gas thermometry

► Used noble gas thermometry to investigate recharge in a mountain-adjacent aquifer. ► Recharge source temperatures were calculated for seasonal irrigation sources and variable water table depths. ► Recharge source temperatures were strongly dependent on mean annual depth to water and water table fluctuations. ► Recharge source temperatures and noble gas temperatures showed values higher than the m.a.t. of the valley floor.
