Get Pricethat silica content of groundwater increases due to increased contact with silicate rocks and that the silica content is directly proportional to the residence time of water in host rock. They also showed that water ascending from deeper reservoirs had higher silica values than in groundwater of shallow origin.
The arsenic, hydrated silica and coexisting ions present in groundwater come from the dissolution of minerals containing rocks in contact with water [1,3,4]. The concentration of arsenic detected in this area varies in a range of 40–134 μg L −1, while hydrated silica fluctuates between 50–132 mg L −1 [ 1, 5 ].
