groundwater abstractions (IMAGE) Helmholtz Centre for Environmental Research - UFZ Caption The pairs of bars show that the full groundwater abstractions for tanker deliveries estimated with the UFZ model for 2015 (pink) substantially exceeded the licensed groundwater abstractions (green) in Jordan’s six monitored groundwater basins. The difference is particularly large in the Amman-Zarqa basin. According to the UFZ model, over seven times more tanker water was illegally abstracted than well licenses permit.
