Sediment samples were taken from a river-groundwater interaction zone which located in Jianghan Plain, central China (114.42890°E, 30.53312°N). Sediments were taken by a 45-mm gouge auger at the depth of 20, 40, 60 and 100 cm, reflecting the profile of redox conditions and Fe(II) contents. The groundwater table was 50 cm below the ground when sampling.
