Hormone-disrupting chemicals found in water at fracking sites

Water samples collected at Colorado sites where hydraulic fracturing was used to extract natural gas show the presence of chemicals that have been linked to infertility, birth defects and cancer, scientists reported Monday.

The study, published in the journal Endocrinology, also found elevated levels of the hormone-disrupting chemicals in the Colorado River, where wastewater released during accidental spills at nearby wells could wind up.

Tests of water from sites with no fracking activity also revealed the activity of so-called endocrine-disrupting chemicals, or EDCs. But the levels from these control sites were lower than in places with direct links to fracking, the study found.
