—A pair of environmental monitoring wells drilled deep into an aquifer in Pavillion, Wyo., contain high levels of cancer-causing compounds and at least one chemical commonly used in hydraulic fracturing,—
So, they found at least two things:
1. cancer-causing compounds
2. one chemical commonly used in hydraulic fracturing
Those are two separate things, right.
And I wonder if that chemical is called dihydrogen monoxide. :-D
You should be thinking of deadly chemical OXIDANE, the substance so deadly because it can harm people in a variety of different ways!
Should liquid oxidane enter into the lungs it blocks the entry of oxygen into the blood, which can cause death in minutes. Even if the oxidane is removed before death occurs, severe brain damage can result. Recreational users are at high risk! In the US every year Thousands of people are killed by Oxidane ingestion!
In gaseous form oxidane causes severe, sometimes fatal, burns by contact with the skin! Liquid and Gaseous Oxidane is a major highway safety hazard and many fatalities occur each year due to Oxidane on the roads or in the air over the roads!
Oxidane is highly susceptible to microbial contamination, such contamination has killed millions of people!
Oxidane is also a major component of Acid Rain, and accumulates in rivers, lakes, and the ocean! When Oxidane is released into the atmosphere it may also evaporate into a greenhouse gas many times more potent than carbon dioxide!
