Abstract

Denitrification driven by pyrite oxidation can play a major role in the removal of nitrate from groundwater systems. As yet, limited information is available on the interactions between the micro-organisms and aqueous and mineral phases in aquifers where pyrite oxidation is occurring. In this study, we examine the groundwater and sediment composition along a well-characterized redox gradient in a heavily nitrate-polluted pyritic sandy aquifer in Oostrum (the Netherlands) to identify the sequence of steps involved in denitrification coupled to pyrite oxidation. Multi-isotope analyses (δ
