Study Finds Harmful Chemicals in Oil and Gas Wastewater

According to a new study published in Environmental Science & Technology, wastewater from oil and gas production, both conventional and using fracking methods, contains levels of the chemicals bromide, ammonium and iodide in concentrations high enough to threaten aquatic life and, when mixed with the chlorine in tap water, to form cancer-causing compounds. Discharge of the wastewater and accidental spills into waterways pose a threat to human health and the environment, according to the study. (Water Online)
