The main source of ground water found in Abu Dhabi is from high elevated Oman Mountains that provide the water to the wades. According to (Brook‚ M.C. et al‚ 2005)‚ total of less than 4% of water used is from groundwater recharge of Abu Dhabi in other word‚ the annual water use in Abu Dhabi is 26 times larger than the annually renewable natural water resources.

Groundwater is an important source of drinking water for more than half of the nation’s population and nearly all its rural population. In recent years‚ widespread reports of bacteria‚ nitrate‚ synthetic organic chemicals and other pollutants in groundwater have increased public concern about the quality of groundwater. What do we know - and what don’t we know - about groundwater quality? What causes groundwater contamination‚ and to what extent are the nation’s groundwater supplies at risk?

conducted during week two. The first was to determine how many contaminates that we put into our water supply will reach our groundwater. The conclusion that I arrived at was‚ that there are still large remnants of contaminates in the groundwater supply after it has had a chance to be passed through soil. We emulated this affect by using smaller amounts of contaminates such as oil‚ vinegar and laundry detergent. Put them in a smaller amounts of water and then passed them though soil. Introduction In

WATER STEWARDSHIP INFORMATION SERIES Hardness in Groundwater February 2007 What is water hardness? Water hardness is primarily the amount of calcium and magnesium‚ and to a lesser extent‚ iron in the water. Water hardness is measured by adding up the concentrations of calcium‚ magnesium and converting this value to an equivalent concentration of calcium carbonate (CaCO 3 ) in milligrams per litre (mg/L) of water. The Guidelines for Canadian Drinking Water Quality Hardness divide hardness
