Historic phenoxy acid waste disposal and spillage at an industrial site close to Copenhagen (Denmark) has contaminated the groundwater with especially mecoprop (RS)-2-(4-chloro-2-methylphenoxy)propionic acid. The contamination is very persistent, probably because it is situated in the subsoil where biological degradation of the contaminant is hindered by lack of oxygen or alternative electron acceptors like nitrate. To examine this, we sampled soil at 3, 4.5 and 6 m depth at the contaminated site and measured the microbial mineralization of mecoprop as affected by nitrate and glucose at nitrate-reducing conditions. The results showed that at these conditions, glucose always had a clear negative impact on mecoprop mineralization. Mineralization of mecoprop was significantly enhanced in soil inoculated with phenoxy acid degraders (p
