Groundwater in the Emirate of Abu Dhabi is contained in consolidated or unconsolidated surficial deposit aquifers and bedrock/structural aquifers. Groundwater is used to meet about seventy-one per cent of the total water demand in the Emirate. Increased demand combined with extensive periods of little to no precipitation has resulted in low recharge rates and groundwater level declines. This map shows the configuration of the water table in Abu Dhabi Emirate. The groundwater table ranges from just below the land surface (near sea level) along the coast to greater than 400 metres above mean sea level (MSL) in the regions around Al Ain. Regions of shallow depth to groundwater may represent areas of concern as they are more susceptible to salt water intrusion and contamination from pollutants.
