Mercury (element) polluted water. They arise by a process known as biomethylation. Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. It is used in some thermometers, especially ones which are used to measure high temperatures. A still increasing amount is used as gaseous mercury in fluorescent lamps, while most of the other applications are slowly phased out due to health and safety regulations and is in some applications replaced with less toxic but considerably more expensive Galinstan alloy. Mercury and its compounds have been used in medicine, although they are much less common today

The CSIA would have required states to co-enforce any requirements laid out by the EPA, i.e. to have funding and man-power to enforce all
