As a result, the abandoned coal mines continued to discharge acid mine drainage rich in iron and highly acidic. This turned much of the river orange down to the confluence of the Pelena with the main river Afan. The Orange colour could often be seen as far down stream as Pontrhydyfen. There were a number of collieries contributing to the pollution although the major source was the Whitworth Colliery. At the height of coal extraction in the valley, there were several deep pits and numerous levels. This pollution is now much mitigated
