In the last years, endocrine disruptors have been a major issue in environmental research. The annual production volume of Bisphenol A (BPA; 2,2-bis(4-hydroxyphenyl)propane), a monomer primarily used to produce polycarbonate and epoxy resins and has been reported to have estrogenic activity, in the EU has reached 1,150,000 metric tons in the years 2005/2006 (EU, 2007).In the present study, phytoremediation of BPA by the halophytes Juncus acutus is investigated at pilot scale. For that purpose, a Shallow Aquifer Rhizodegradation Pilot has been designed. The Pilot uses Juncus acutus in a continuous overflowing treated groundwater system. The separation and quantification of BPA in wastewater samples is carried out by HPLC, in order to monitor the process of BPA concentration levels. In addition the adsorption by the soil, at several concentration levels, has been investigated in lab-scale experiments in the absence of plants.
