    摘要： A method for remediation of environments contaminated with halogenated organic compounds, in particular per- and polyfluoroalkyl substances, the method comprising the steps of placing a plurality of electrodes in the contaminated environment, applying an electric direct current between said electrodes, providing at least one electrically conductive reductant for halogenated organic compounds, obtaining information indicative of the electrical resistance between said electrodes, analyzing said information to detect whether at least one of said electrodes introduced a lower electric current into the contaminated environment compared to the remaining ones of said electrodes and bringing said reductant into or in close proximity to the contaminated environment in response to said detection such that the electrical resistance to the contaminated environment of at least one of said electrodes identified to introduce a lower electric current into the contaminated environment is decreased.

    摘要： Die Erfindung betrifft eine Filteranordnung (1) mit einer Mehrfachanordnung von in einem unterirdischen Schacht angeordneten Filtereinheiten (4). Die Filtereinheiten (4) sind im Schacht in Abstand übereinander angeordnet, wobei zwei benachbarte Filtereinheiten (4) durch eine wasserdichte Schicht von Quellmaterial (6) getrennt sind. An den einzelnen Filtereinheiten (4) münden periphere Steigrohre (7) aus, die bis zur Erdoberfläche (2) verlaufen.
