Boron in Hungary is present in drilled wells, and belongs to the family of borates. Hungary does not really have a high boron content in the waters, it is more present in higher concentration in South America and seawater, but due tot he toxic effect of boric acid, the current drinking water regulation prescibes a relatively low limit value, wich is now 1 mg/l. If the value is highr than this, a boron removal device is used. In the past, this was a very expensive process, as only boron could be removed by distillation as well as RO equipment, but now resin and ion exchange charges are also available for this task.
