People who consume high levels of heavy metals like iron in water are at risk of acute and chronic toxicity, liver, kidney, and intestinal damage, anemia, and cancer. It also takes its toll on your laundry, dishwares, and water receptacles and leaves red or brown stains that are difficult, it not impossible, to remove. It can clog dishwashers, washing machines, sprinklers, water pumps, and other similar appliances too.
Copper is part of our dietary need; however, consumption of high levels of this element can cause nausea, headache, diarrhea, and gastric disorders; and long term exposure may cause severe liver damage and even death.
Lead, unlike other metals, is not beneficial or necessary for humans and can be harmful to your health. Infants and children are especially vulnerable as lead can impair their brain development. A dose of lead that would have little effect on an adult can have a significant effect on a child.
