Grand Junction, Colo. (KKCO) --- Hydraulic fracturing, or fracking, is a common practice in the oil and gas industry here in Colorado.
But now experts are warning that long-term exposure to the technique, may lead to some disturbing health issues.
People living, working or even going to school near fracking rigs can be subjected to increased air pollution and even possible water contamination.
"We have to put the health and safety of humans first," said registered nurse and Palisade resident, Benita Phillips. "Nature will take care of us if we do what's right, and we're not doing what's right."
Some of the contaminants that may be used in fracking include diesel, formaldehyde, sulfuric acid, benzene and lead, to name just a few.
Doctors say that as with many other toxins, exposure to small amounts of them over a long period time can eventually lead to serious health problems.
