Arsenic

As a naturally occurring chemical compound, arsenic is found in most bodies of natural water in the form of salt. Though this is typically found in very small concentrations in nature, this compound is also a byproduct of industrial and agricultural pollution. Continually drinking water that contains arsenic can have a severe impact to a person’s health, especially to the cardiovascular system. Arsenic exposure has even been demonstrated to lead to cancer if large enough quantities are taken for a prolonged period of time.
