Selenium Water Treatment and Selenium Water

Because selenium is useful in many industrial settings, it is used to build electronics such as photocopier parts but can also be found in glass, rubber, fabrics, and medical therapies ;runoff is possible and this is how selenium would be most likely to enter the water supply. The MCL for selenium has been set by the EPA at 0.05 ppm.
