Arsenic in Idaho’s drinking water
The arsenic in Idaho probably comes from volcanic activity through the ages, but when it settles in our drinking water and raises warning flags about increased risk of cancer and other diseases, we pay attention.
Officials for Kuna, Idaho, have shut down one of the city’s main water wells because it was found to have more than the amount of arsenic allowed by the EPA for drinking water. A fact sheet by the EPA explains the reasons for a higher standard of arsenic in drinking water, from 50 parts per billion in 1975 to 10 parts per billion in a recent action.
The Centers for Disease Control (CDC) summarizes how arsenic affects the human body, and Amethyst Galleries gives an interesting description of where this chemical comes from and how it reacts with other chemicals. If there’s an inquisitive student inside you, pay a visit to WebElements and see what they have to say about arsenic.
