Characterization and fingerprinting of soil and groundwater contamination sources around a fuel distribution station in Galicia (NW Spain)

Soil and groundwater contamination around a fuel distribution station in Tomino (NW Spain) was evaluated. For this purpose, top and subsoil (up to 6.4 m) and groundwater were sampled around the station, approximately in a 60-m radius. Samples were analysed by HS-SPME-GC-MS to identify and quantify volatile fuel organic compounds (VFOC) (MTBE, ETBE and BTEX) and diesel range organics (DRO). Analysis and fingerprinting data suggested that the...
