The groundwater body is a highly sensitive receptor which is facing a great threat by environmental pollution. Contaminated land is amongst the most important sources of adverse impact on groundwater as potentially harmful substances may migrate from the surface into the vadose and eventually the saturated zone of the subsurface. Polycyclic Aromatic Hydrocarbons (PAH) and petroleum hydrocarbons (TPH) are present at a great number of sites and pose a serious threat to the soil and groundwater system. Biological in-situ remediation methods (“bioremediation”) are promising alternatives to conventional treatment methods. Biologically based remediation actions aiming at the elimination of PAH and TPH to date require aerobic subsurface conditions, which in many cases need to be established in the subsoil at great expense. The demand for oxygen for contaminant breakdown exceeds its solubility in water by far and thus states an essential limitation for the efficient biological turnover of organic compounds. With no oxygen available, naturally occurring decontamination processes are slowed down or cease entirely, possibly with the formation of unknown and more mobile or even more toxic metabolites.
However, there are a number of conceivable methods to circumvent the limitation to degradation that is posed by the absence of dissolved oxygen (DO) in groundwater, and thus to allow for efficient contaminant removal even in the saturated zone. In the current project, the following methods will be characterized thoroughly in its fundamentals, developed and tested for their applicability under lifelike conditions: (i) increase of DO via the introduction of pure oxygen, (ii) introduction of chemically fixed oxygen plus (iii) anaerobic oxidation.
