Testing for the presence of heavy metals in water is likewise difficult, with most home water test kits only detecting the “Big Three: copper, lead and iron. We shall now look at the ill-effects of these heavy metals on our bodies. Heavy metals can contaminate private wells through groundwater movement and surface water seepage adn run-off. Heavy metals, like arsenic, lead, mercury, and others, are all around us. Runoff from industrial waste, acid rain gets absorbed into the soil, consumer waste contaminates the water supply, and even the pipes in our homes and contribute to heavy metals in our drinking water. It can be seen from the table that the heavy metal pollution in sediments in different regions is quite different.

Today, heavy metal contamination in drinking water poses a threat to humans and is often the root cause of various severe health issues such as cancer, organ damage and other serious health issues.

Mohammad Ali Salik. Water pollution due to Heavy Metal Ions (HMIs) is a global issue which requires proper attention to maintain the water quality demands. The presence of heavy metals cannot be seen with naked eyes and can be detected by a water … Experts at testing water for metals, heavy metals & other contaminants. Water Softeners use ion exchange technology for chemical or ion removal to reduce the amount of hardness (calcium, magnesium) in the water; they can also be designed to remove iron and manganese, heavy metals, some radioactivity, nitrates, arsenic, chromium, selenium, and sulfate. Drinking Water Regulations.

Heavy metals commonly found in stormwater include copper, lead and zinc, from: Rooftop runoff . Soils may become contaminated by the accumulation of heavy metals from scrap metal recycling, mine tailings, manufacturing, gas, fertilizers, sewage sludge, pesticides and many other sources. The legal limit for a contaminant reflects the level that protects human health and that water systems can achieve using the best available technology. Exposure to even small amounts of heavy metals in drinking water can result in severe health effects. Prevention. Water Softeners. Lead and Iron) "Heavy Metals" in the water treatment field refers to heavy, dense, metallic elements that occur only at trace levels in water, but can be very toxic and tend to accumulate in the body over long periods of time. What happens when an excess of metals enters freshwater ecosystems?
