This is the final report for the joint Welsh Office and NRA funded study of ferruginous minewater impacts in Wales. The study took place between October 1992 and October 1993. Ferruginous minewater discharges from abandoned coal mines in the South and North Wales coalfields have been causing problems to receiving watercourses for many years (eg. Pelenna catchment). The rapid contraction of coal mining in the South Wales coalfield resulted in the closure of many of the remaining pits during the 1980s, leaving Tower colliery, near Aberdare, and Bettws colliery, near Ammanford, the last remaining deep mines in South Wales. The spate of mine closures, in recent years, has resulted in several new ferruginous discharges to a number of rivers, particularly in the eastern area of the coalfield and the effects of these discharges on the aquatic environment are of growing public concern (eg. R. Rhymney at Hengoed).
