Long description: Leachates generated by old colliery spoil heaps can pose significant risks to ecosystems, drinking water supplies and agricultural uses of surface waters. As regulatory controls have tightened over the years, it has also become apparent that the risks posed by such sites are likely to persist for hundreds of years in most cases. Thus, remedial interventions which can be readily sustained over long time periods are increasingly required. Given that such treatment may have to be sustained for centuries, conventional 'active' treatment technologies such as lime dosing and sedimentation (which have high operating costs) are unappealing. Passive treatment options (in which most expenditure is concentrated in construction costs and operating costs are minimal) are far more attractive.
