Copper

Copper, we filter that.

COPPER is a metal that occurs naturally in rock, soil, plants, animals, and water. Since copper is easily shaped or molded, it is commonly used to make electrical wiring, and household plumbing materials. Copper may be combined with other metals to make brass and bronze pipes and faucets. Copper compounds are also used as agricultural pesticides and to control algae in lakes and reservoirs. All living organisms including humans need copper to survive; therefore, a trace amount of copper in our diet is necessary for good health. However, some forms of copper or excess amounts can also cause health problems.
