More research finds that fracking fills groundwater with toxic poisons

The chemicals that fracking introduces into drinking water include known carcinogens and hormone disruptors.

Chemicals Found In Water At Fracking Sites Linked To Infertility, Cancer | ThinkProgress

An analysis of water samples from hydraulic fracturing, or ‘fracking,’ sites found the presence of hormone-disrupting chemicals, according to a new study published Monday in the journal Endocrinology.

“With fracking on the rise, populations may face greater health risks from increased endocrine-disrupting chemical exposure,” senior author Susan Nagel told The LA Times.

The study tested surface water and groundwater samples in Garfield County, Colorado — one county at the center of the U.S. fracking boom — and found elevated levels of endocrine-disrupting chemicals, or EDCs. The chemicals have been linked to infertility, birth defects, and cancer.

Dr. Meg Schwarzman, associate director of the Berkeley Center for Green Chemistry at UC Berkeley, told The LA Times that “even low levels of anti-estrogenic or anti-androgenic activity could potentially alter development in ways that are meaningful.”

The researchers gathered samples from five sites where there have been natural gas production spills over the last six years and compared those to control sites where there is no fracking activity. The fracking sites “exhibited more estrogenic, anti-estrogenic, or anti-androgenic activities than reference sites with limited nearby drilling operations,” leading researchers to conclude that “natural gas drilling operations may result in elevated EDC activity in surface and ground water.”
