Purge-and-trap coupled to gas chromatography–mass spectrometry was optimised for the simultaneous determination of the above mentioned compounds and enabled to detect concentrations at ng/l or sub-μg/l concentrations. Special attention was given to the determination of polar MTBE degradation products, TBA and TBF, since not much data on method performance and environmental levels are given on these compounds in groundwater. All samples analysed contained MTBE at levels between 0.3 and 70 μg/l. Seven contaminated hot spots were identified with levels up to US Environmental Protection Agency drinking water advisory (20–40 μg/l) and a maximum concentration of 670 μg/l (doubling the Danish suggested toxicity level of 350 μg/l). Samples with high levels of MTBE contained 0.1–60 μg/l of TBA, indicating (but not proving) in situ degradation of parent compound. In all cases, BTEX was at low concentrations or not detected showing less solubility and persistence than MTBE. This fact confirms the suitability of MTBE as a tracer or indicator of long-term gasoline contamination than the historically used BTEX.This research is part of the WATCH (EVK1-CT-2000-00059) EU project funded by the EU Environment and Sustainable Development sub-program and from the Ministerio de Ciencia y Tecnología (REN2001-5039-E).Peer reviewedElsevier200920092003info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_650122195 bytesapplication/pdfhttp://hdl.handle.net/10261/19660reponame:DIGITAL.CSIC.
