Popis: Arbor Colliery is an abandoned colliery in the Loskop Dam catchment. The mine comprises a series of opencast pits, as well as poorly defined underground workings. The water within the opencast pits shows high levels of acidity, elevated sulfate levels and elevated metals (Al, Fe and Mn). Some 100 families live adjacent to the mine, and this presents interesting social challenges in terms of remediation. The mine will be rehabilitated over a period of several years. The remediation strategy proposed is discussed, together with some of the ongoing tests and issues still to be resolved. ______________________ 1 Paper presented at the 7 th International Conference on Acid Rock Drainage (ICARD), March 26-30, 2006, St. Louis MO.
