Chromium has a large influence upon drinking water quality. It cannot normally be found in groundwater and surface water in considerable concentrations. Specific removal in sewage water treatment is therefore unusual. Chromium removal from water is optional, because both ion exchangers and active carbon can be applied for this purpose.
