What Is Selenium?

Selenium is a metal found in natural deposits such as ores containing other elements.  Selenium compounds are used largely in electronic and photocopier components but they are also widely used in glass, rubber, metal alloys, petroleum, medical therapeutic agents, and photographic emulsions.

Is It Harmful?

Some people who drink water containing selenium well in excess of the maximum contaminant level (MCL) for many years could experience hair or fingernail losses, numbness in fingers or toes, or problems with their circulation.

How Does Selenium Get Into My Water?

The main sources of selenium in drinking water are discharge and contamination from petroleum and metal refineries. Other sources include erosion of natural deposits and discharge from mines.

What Are My Treatment Options?

EPA approved treatment methods are:

  • Activated alumina
