Elimination of pathogens and emerging pollutants represents a key factor in integrated water resources management in arid regions. 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-beta-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. Viruses were shown to be present in most of the Jordan Valley surface water samples. MBR treatment resulted in a decrease of MS2 bacteriophages used as model viruses.
