Within the SMART Jordan Valley project it is the objective of this study to assess the occurrence and examine the elimination of selected emerging pollutants and pathogens in waste water treatment and aquifer recharge. In batch and soil column studies non-chlorinated organophosphorous compounds (tri-n-butylphosphate, triphenylphosphate) and endocrine disruptors (e.g. 17-ß-estradiol, bisphenol A) proved to be biodegradable, while the X-ray contrast agents iomeprol and iopromide were eliminated in the soil columns only, and the chlorinated trialkylphosphates showed persistency. Treating waste water in a membrane bioreactor (MBR) in combination with powdered activated carbon (PAC) resulted in considerable removal rates also for the more persistent compounds such as the antiepileptic carbamazepine.

The area between the Northern Frontier of the Hashemite Kingdom of Jordan to the North and the Northern edge of the Dead Sea to the South and the Jordan River to the West until elevation 300 meter above the sea level to the East. 2. The area between the Northern edge of the Dead Sea to the North, and to the Southern boundary of Qatar village to the south (Wadi Araba), and to the western frontier of the Hashemite Kingdom of Jordan to the West, and to elevation 500 meter above sea level to the East.

Water management studies reveal that no single source could fully solve the nation's water shortage and many integrated actions are needed to ensure water availability, suitability and sustainability. Among these options the developments of new water resources such as treated wastewater and brackish water have the potential to augment water supplies, thereby narrowing the gap between available freshwater and total demand. Agriculture is one of the primary essential activities in Jordan in general and in the Jordan Valley in particular. Treated waste water is could be a valuable source for irrigation in the agricultural sector, as an alternative for fresh water resources that are urgently needed by the rapidly growing urban populations. Currently there is an increasing percentage of irrigated a...

Natural recharge takes place by infi ltration from rainwater or streams. Rare but intensive rainfall events can generate fast runoff in the mountains where surface water is conducted through wadis to the Jordan Valley, but only a small amount infi ltrates naturally into the ground. To optimize the use of fl oodwaters, several storage dams were constructed in Jordan during the last decades along the slopes of the Jordan Valley. One of these is the Wala dam in Madaba region in Jordan. Its main function is to store water during the winter season and recharge it into the underlying Wadi Es Sir Limestone aquifer. Groundwater from this aquifer is used for the drinking water supply to nearby communities (Sawarieh et al. 2010). Since its completion in 2002, the Wala reservoir fi lls during wint...
