Descripción: Passive seismic interferometry takes advantage of natural ambient seismic noise generated by the wind, the storms and the human activities (e.g. cars, trains and hereafter pumps) to recover the slight variations of the seismic wave velocity induced by changes in the groundwater level. Here we compare the seismic measurements with actual piezometric data acquired on the Crépieux-Charmy (Lyon, France) groundwater exploitation field. We show the excellent correspondance between variations in the groundwater level and seismic velocity variations. We present hereafter the time and space monitoring of an hydraulic dome formed to prevent biological and chemical pollutions to enter the exploitation field. The vertical resolution of seismic measurement corresponds to a 20 cm change of waterlevel; the horizontal resolution is solely limited by the number of seismic stations used, and is about 30 m in the present study. This study confirms the possibility of groundwater monitoring in an industrial context with ambient seismic noise.
