In this study, the effectiveness of coagulation was assessed in arsenic removal from the Zarqa, Jordan and Yarmouk River. Graphite-Furnace Atomic Absorption Spectrophotometry (GF-AAS) technique was used to analyse the arsenic percentage. The Zarqa River recorded the highest arsenic value at upstream and had the lowest value at downstream. The highest percentage of arsenic content in the Zarqa River is 69.81 ppb while the Yarmouk River showed the lowest concentration (7.003 ppb) before the coagulation process. Reduction in the concentration of arsenic was achieved up to 57.001 ppb for Zara River and 5.91 ppb for Yarmouk River after the coagulation test. This indicates that the coagulation technique significantly able to remove up to 20% of arsenic content.
