The current study describes the abundance of 42 selected emerging organic contaminants (EOCs), including human and veterinary antibiotics, UV-filters and analgesics in the groundwater of the urban aquifer of Zaragoza (Spain), which is affected by intensive exploitation of shallow geothermal resources. The presence of groundwater heat pump systems in the aquifer studied offered the opportunity to study the occurrence of EOCs in relation to groundwater temperature and other physicochemical effects derived from this technology. Analysis of the data obtained allowed us to identify statistically significant relationships between the presence of EOCs and temperature, as well as other physicochemical and geochemical properties of groundwater. The results obtained suggest that temperature is a minor factor controlling the degradation of the organic compounds analysed compared to the oxygen input from groundwater heat pump systems which is possibly increasing the aerobic redox conditions, thus preventing the degradation of organic pollutants. Intensive use of shallow geothermal resources therefore seems to contribute in the prevalence of such compounds in the aquifer close to geothermal systems. 000084211 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000084211 590__ $$a4.405$$b2018 000084211 591__ $$aENGINEERING, CIVIL$$b6 / 132 = 0.045$$c2018$$dQ1$$eT1 000084211 591__ $$aWATER RESOURCES$$b6 / 91 = 0.066$$c2018$$dQ1$$eT1 000084211 591__ $$aGEOSCIENCES, MULTIDISCIPLINARY$$b15 / 195 = 0.077$$c2018$$dQ1$$eT1 000084211 592__ $$a1.83$$b2018 000084211 593__ $$aWater Science and Technology$$c2018$$dQ1 000084211 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000084211 700__ $$aGarrido Schneider, E. 000084211 700__ $$aMejías, M. 000084211 700__ $$aBarceló, D. 000084211 700__ $$aVázquez-Suñé, E. 000084211 700__ $$aDíaz-Cruz, S. 000084211 7102_ $$12000$$2427$$aUniversidad de Zaragoza$$bDpto.
