Sediment biomarker, bacterial community characterization of high arsenic aquifers in Jianghan Plain, China.

In the borehole of S–02, As is low in the depth of 30 to 28 m (the mixed silt and sand layer), while it increases to 10 μg/g in the mixture of silt and sand layer (from 26 to 24 m); then it decreases to around 3 μg/g in the clay and the mixed soil and sand layer (20 m to 12 m), followed by an increasing trend in the top soil layer (10 m to the surface).

Specifically, the As concentrations in the borehole of S–01 range from 3.5 to 9.1 μg/g from the depth of 20 m to 6 m with a slightly increasing trend at the depth of 12 m.
