    New Study 74 of US gold mines pollute water Earthworks

    Water flowing through active or abandoned mine sites can become polluted by the material being mined1. By far the most common mine drainage problem is that of acid mine drainage AMD. Sulfuric acid is produced when water interacts with sulfur-bearing materials in the presence of oxygen and common bacteria1. The acidic water formed by this process can dissolve many metals.Formation of acid mine drainage is one of the most important causes of water pollution. Other potential contaminants include oils and fuels, chemicals used in concentration processes and nitrogen compounds from explosives. Legislative framework and Finnish national guidelines.
