About 118, 000 Wells 3. About 70% are working wells (which is about 82,000 wells) About 30% abundant wells (which is about 34,800 wells) PAGE 8

9 ENVIRONMENTAL AND ECONOMICAL IMPACTS PAGE 9

10 CHALLENGES AND THREATS Aridity and Scarcity Institutional and Legal Fragmentations Over Abstraction Quality Deterioration Increasing Demand PAGE 10

11 GROUNDWATER INTEGRATED MANAGEMENT FRAMEWORK The GW Policy Provide science based information to help forming an effective policies, like: Specify the GW stressed zones Report on the GW Reserves (Qty and salinity) Exchange existing well datasets Increase accuracy of existing data (water use data) Project: Well Inventory Law No. 5, 2016 GW Metering Provide science based analysis to: Define selection criteria for meter installations jointly with concerned members incorporating: depleted areas abstraction rates GW Salinity Intensify GW inspection operations in the GW stressed areas Strengthen the practical knowledge GW Enforcement Well Permitting Validate GW allocations Enhancing permitting procedure and criteria within stressed areas PAGE 11

13 ABU DHABI GOVERNMENT EFFORTS AND INITIATIVES Groundwater Regulation 2006 Law no 6/2006 Executive Order (March 2007) Groundwater Wells Drilling Law 2016 Law no 5/2016 Groundwater Regulation Law Drilling license Well rehabilitation license Abstraction permission Small scale desalination for agriculture use permission 2018 Executive Order (for Law no 5/2016) Groundwater Regulation Law PAGE 13

14 Criteria Elements ABU DHABI GOVERNMENT EFFORTS AND INITIATIVES Groundwater Levels Monitoring Develop methodology and criteria to select GW monitoring wells 1300 wells were assessed accordingly 640 wells out of 1300 selected for GWM Remaining wells are available for other monitoring purposes or standby as replacement wells Automation after optimization X: Not required Aquifer systems Saturated thickness Depleted areas Land uses well fields Well design Historical monitoring data Well conditions PAGE 14

15 Quality Criteria Elements ABU DHABI GOVERNMENT EFFORTS AND INITIATIVES Groundwater Quality Monitoring Design Process: Overall GW quality results assessed GW quality criteria Developed Target locations determined, along with frequency and target parameters for analysis. Sampling SoPs developed GW salinity Catchment areas* Land uses Water table Chemical concentrations Hydrogeological Characteristics PAGE 15
