Removing The Selenium In WaterAt low levels, consuming the selenium in water produces no known health effects. But as you read on, you'll see there are potential dangers if it is consumed at higher amounts. Potential Source of Contamination: Selenium is a metal found it natural deposits. It is used to make electronic components and in other other industries such as the petroleum and metal refineries. Water runoffs from these industries may cause water supplies to be contaminated with selenium. Drinking Water Standards: The EPA species the maximum amounts that specific contaminants may exist in our water supply. This measure is called the Maximum Contaminant Level (MCL). When a particular contaminant exist above the MCL, local water authorities are duty bound to inform their customers within 30 days. They are also supposed to take corrective measures that reduce the contaminant to levels below the MCL. The MCL for selenium in drinking water is 0.05 mg/L. Health Effects: Consistently drinking tap water that contains amounts of selenium that are above the MCL could lead to liver damage, problems with circulation, numbness in fingers and toes and loss of hair and fingernails. Home Water Treatment: To achieve selenium removal from water, you'll need a water filtration system certified to NSF Standard 58 or 62, namely a home water distiller or reverse osmosis water filtration system.
