Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once discharged. So it is important to know if there are heavy metals in your water because these contaminants can pose a serious health threat. And removal of heavy metal from source water is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can naturally exist in ground water. Lead can be present as a result of lead solder in copper pipes. Mercury and cadmium can be a result of power plant emissions. Additionally, a variety of industrial processes can produce problematic heavy metal concentrations in discharged water from factories that are harmful to humans and can contaminate agricultural land. Exposure to certain metals, such as mercury and lead, may result in developmental, neurological, gastrointestinal, and reproductive damage. The toxic effects of ingesting large amounts of heavy metals can be poisonous and may lead to prolonged illness. The following table shows the 2010 water supply regulations that publish a limited list of heavy metals that should not be exceeded in drinking water.
