Abstract
In the spring the of 1993 the Ynysarwed mine water discharge in south Wales became a serious problem affecting a 12km length of the Neath Canal. As a result of the severity of the discharge, pH 3.5, 400mg/l Fe, a combination of active and passive treatment steps were installed. Chemical dosing was stopped in 2009 as conditions had improved pH>5, 100mg/l Fe. The existing mine water treatment scheme is in the process of being reviewed. Different treatment options are being considered including stripping dissolved Co₂ from the mine water, thereby maintaining mildly acidic pH and accelerating Fe(II) oxidation rates.
