Cover Story: Groundwater supports human well-being, especially in areas where it is the primary drinking water source. This work illustrates an application of the Ecosystem Services Assessment framework to support aquifer management by evaluating future trends in the provisioning service Groundwater of Good Quality for Human Supply in the Medina del Campo Groundwater Body (MCGWB, Spain). In the MCGWB, the intensification of agricultural activities and groundwater exploitation since the 1970s has caused severe nitrate pollution. By combining groundwater flow and nitrate transport modelling, we assessed the expected impacts of fertilizer and aquifer management scenarios on nitrate attenuation. Results show that reducing fertilizer load is more effective than decreasing groundwater abstraction to improve the provision of groundwater for human supply. View this paper
