Endocrinologists are warning us in a paper for an upcoming issue of the
that some of the chemicals used in hydraulic fracturing - fracking - can disrupt the body's hormones.
Of course, that also applied to chemicals in everything you ate at Thanksgiving dinner.
Lesson: Don't drink endocrine-disrupting chemicals. Also, don't touch numerous manufactured products, air, water and soil. Endocrine-disrupting chemicals have been linked to infertility, cancer and birth defects.
"More than 700 chemicals are used in the fracking process, and many of them disturb hormone function," said one of the study's authors, Susan C. Nagel, PhD, of the University of Missouri School of Medicine. "With fracking on the rise, populations may face greater health risks from increased endocrine-disrupting chemical exposure."
How? No fracking chemicals are getting into drinking water.
Nonetheless, they are going to tell you that the chemicals you aren't drinking will be bad for you if you do. They examined 12 suspected or known endocrine-disrupting chemicals used in natural gas operations and measured their ability to mimic or block the effect of the body's male and female reproductive hormones. To gauge endocrine-disrupting activity from natural gas operations, researchers took surface and ground water samples from sites with drilling spills or accidents in a drilling-dense area of Garfield County, CO – an area with more than 10,000 active natural gas wells – and from drilling-sparse control sites without spills in Garfield County as well as Boone County, MO.
The water samples from drilling sites had higher levels of EDC activity that could interfere with the body's response to androgens, a class of hormones that includes testosterone, as well as the reproductive hormone estrogen. Drilling site water samples had moderate to high levels of EDC activity, and samples from the Colorado River – the drainage basin for the natural gas drilling sites – had moderate levels. In comparison, little activity was measured in the water samples from the sites with little drilling.
"Fracking is exempt from federal regulations to protect water quality, but spills associated with natural gas drilling can contaminate surface, ground and drinking water," Nagel said. "We found more endocrine-disrupting activity in the water close to drilling locations that had experienced spills than at control sites. This could raise the risk of reproductive, metabolic, neurological and other diseases, especially in children who are exposed to EDCs."
