Filters in household faucets and genetic technology could help reduce this public health threat, biologist Rebecca Fry says Credit: Michael Hall Getty Images Arsenic’s potent effect on humans has been known since at least the Roman Empire. For centuries, it was a popular poison for murderers because it can’t be seen, smelled or tasted in food or water. That made it difficult to detect. As chemical detection methods improved, its use as a poison declined. But arsenic, a naturally occurring chemical element in the Earth’s crust, remains a threat to human health. Regular, long-term exposure increases the risk of chronic disorders such as cancer, diabetes and heart disease for millions of people around the world.

Iron is one of the major secondary contaminant in both domestic and industrial water supply. Iron have caused water industries several billions of dollars . Iron is the second most abundant metal in the earth's crust behind Aluminum(8%), of which iron accounts for about 5%. Elemental iron is rarely found in nature, as the iron ions Fe2+ and Fe3+ readily combine with oxygen- and sulfur-containing compounds to form oxides, hydroxides, carbonates, and sulfides. As rain fall, rain water infiltrates the soil and underlying geologic formations and dissolves iron, causing it to seep into aquifers that serve as sources of groundwater for wells. In surface water, such as rivers and lakes, dissolved iron is hardly ever found, because it readily reacts with oxygen, forms insoluble compounds and sinks out into the bottom of the water body. Iron is seldom found at concentrations greater than 10 milligrams per liter (mg/L) or 10 parts per million. The iron that seep into the sources of g
