Arsenic Removal in Groundwater | Water Quality Products
Arsenic is naturally occurring in groundwater in both the arsenite and arsenate forms. Found in rocks, soil, water, air and biota, arsenic's natural concentrations in soil typically range from 0.1 to 40 mg/kg. Arsenic's carcinogenic role was noted more than 100 years ago, and it has also been linked to diabetes and neurological disorders.
