Surface and pipe disorders have caused environmental and property damage and fears about their safety. Potential groundwater contamination is a problem with underground disposal methods. The washing or cleaning process reduces contaminants causing coal pollution, but these impurities will then become part of the porridge. The composition of the sludge of coal varies depending on coal and processing methods. Coal and preparation waste products contain potentially toxic organic and inorganic compounds, sulphates, ammonium and heavy metals.
