In February 2010, a hydrometric station was installed at the ''Qasser al-Yahud'' baptism site (740992E, 3525198N UTM Z36) in the Lower Jordan River, including an automatic water sampler (Andress and Hauser Liquiport 2000), and an independent EC-sensor (Condumax CLS12). In total, 428 water samples representing the time period 2010/03/26- 2012/07/09 were collected, filtered (0.22 µm PVDF) and analyzed for anions (Cl, Br, NO3, SO4) applying IC Dionex DX-320 and for cations (Na, K, Mg, Ca) applying IC Dionex DX-500, both with conductometric detection.
