Marcasite occurs in highly acidic and with low temperatures conditions, mainly on sedimentary rocks or hydrothermal veins. It is formed on alteration of chemicals of a parent mineral such as chalcopyrite. It reacts in high humidity to form iron (II) suphate and sulphuric acid. It is used mainly used for ornamental purposes and a source of sulphur.
Despite the benefits attributed to the emergence of bottled water, a number of negative environmental and health challenges have emerged. These have affected the universal acceptance of this technology and increased the controversies
