Selenium Water Test

In very small quantities, selenium is an important nutrient. But when selenium levels in drinking water get too high, serious problems can result, such as fingernail or hair loss, circulation problems or numbness in extremities. Levels can get too high as a result of nearby industrial activities, such as mining or refining, or from runoff from lands naturally high in selenium.

Is Selenium in My Water Harmful?
Selenium can enter water supplies from naturally occurring sources or from manufacturing operations. It is used in producing glass, electronics, paints and inks. Short-term consumption of water with high levels of selenium can cause vomiting, nausea and diarrhea.

How Much Does a Selenium Water Test Cost?
For $50, you can determine if your water has selenium levels in excess of the 50 parts per billion standard set by the EPA.
