<jats:title>Summary</jats:title><jats:p>Arbuscular mycorrhizal fungi (<jats:styled-content style="fixed-case">AMF</jats:styled-content>), which are present in most natural environments, have demonstrated capacity to promote biodegradation of organic pollutants in the greenhouse. However, it is not certain whether <jats:styled-content style="fixed-case">AMF</jats:styled-content> can spontaneously establish in phytoremediation systems constructed to decontaminate groundwater, because of the unusual conditions during the construction and operation of such systems. To assess this possibility, root samples from a wetland constructed for the phytoremediation of groundwater contaminated with benzene, methyl <jats:italic>tert</jats:italic>‐butyl ether and ammonia were analysed. Substantial <jats:styled-content style="fixed-case">AMF</jats:styled-content> colonization was observed in plant roots sampled close to the inlet of a basin filled with fine gravel and planted with <jats:italic><jats:styled-content style="fixed-case">P</jats:styled-content>hragmites australis</jats:italic>. In addition, analysis of a fragment of the nuclear large ribosomal subunit, amplified by nested <jats:styled-content style="fixed-case">PCR</jats:styled-content>, revealed the presence of <jats:styled-content style="fixed-case">AMF</jats:styled-content> molecular operational taxonomic units closely related to <jats:italic><jats:styled-content style="fixed-case">F</jats:styled-content>unneliformis mosseae</jats:italic> and <jats:italic><jats:styled-content style="fixed-case">R</jats:styled-content>hizophagus irregularis</jats:italic> in the samples. These findings demonstrate the capacity of generalist <jats:styled-content style="fixed-case">AMF</jats:styled-content> strains to establish spontaneously, rapidly and extensively in groundwater bioremediation technical installations.</jats:p>
