Within the last decade, multicomponent seismic imaging has proven to be beneficial in various areas ofapplications, from hydrocarbon to mineral exploration, as well as for environmental and infrastructure planninginvestigations. To demonstrate the potential and need for multicomponent seismic imaging for infrastructureplanning project, we show an example of a seismic profile acquired using a recently developed digital-based 3Cseismic landstreamer and a cost-effective drop-hammer seismic source for planning of wells for pumping water(aquifer recharge) at an esker site that supplies drinking water for the entire city of Turku, Finland. The studyillustrates the importance of 3C data recording and shows the potential of the landstreamer in imaging theshallow subsurface using both P- and SH-waves generated from the vertical impact source. Synthetic modeling,particle motion studies and surface-wave analysis of the data are used to scrutinize the data and investigate thenature of the signal and underlying physical properties of the subsurface
