GEO-log GmbH, based in Braunschweig, used a Geoprobe 6620DT at an abandoned airfield in eastern Germany for a limited membrane interface probe (MIP) investigation project. The goal of the project was to identify a plume of benzene, toluene, ethylbenzene and xylenes (BTEX), polycyclic aromatic hydrocarbons (PAHs) and hydrocarbons released by single sources within the tank farm of the airport. According to Axel Oppermann, company director of geo-log, the firm used its MIP logging system, DT21 soil sampling system and SP16 groundwater sampler to depths of 11 m to map the jet fuel contamination. A second field team was needed for the project, so geo-log called upon Dr Johannes Koerner, of Dr Koerner Geomonitoring, Tuebingen, to provide a 6610DT and field technicians for the work.
