The present invention provides a system for remediation of a xenobiotic in a liquid. The system comprises: a first chamber having a first port and a second port, a first electrode in the first chamber, a second electrode is in electrical communication with the first electrode and with a voltage source, wherein the first electrode is an anode and the second electrode is a cathode or the first electrode is a cathode and the second electrode is an anode. The system uses an electric current to provide an electron acceptor or electron donor for a microorganism capable of remediating the xenobiotic.
