Beryllium

MCL: 0.004 ppm

Source: Is found naturally as a mineral and an ore. Discharge from industrial processes may lead to contamination of water sources.

Summary: Beryllium, element 4 on the periodic table, is found naturally in minerals such as beryl (emerald is a type of beryl!). Beryllium is insoluble in water. Due to its relatively low density but high strength, it has many applications for the aerospace industry. Beryllium is also resistant to corrosion and has a high melting point. Alloys of beryllium (mainly with copper) have a wide range of applications in industrial production of electrical components and tools. Beryllium copper alloys are favored for their non-magnetic properties while maintaining high strength and resistance to corrosion, as well as relatively high electrical and thermal conductance. Resistant to x-rays, it is used in the windows of x-ray tubes to improve strength and visibility.
