A new Texas\u00a0study<\/a>\u00a0has found that horizontal oil wells fractured by the injection of high volumes of chemicals, sand, and water contaminate nearby water wells with a variety of heavy metals and toxic chemicals that fluctuate over time.<\/div>\n

In the last decade, North America’s $40-billion fracking industry has punctured uneconomic or ”unconventional” rock formations from British Columbia to Texas with long lateral wells that extend for miles underground.<\/p>\n

Then they blast open the surrounding formation with injections of water, chemicals, sand, fluids, or hydrocarbons. But industry can’t always control the direction of the fractures.<\/p>\n

”In our most recent study, we found that as more unconventional wells were drilled and stimulated, more drilling-related contaminants were found in the groundwater,” study author Zacariah L. Hildenbrand told The Tyee.<\/p>\n

Dichloromethane, an industry\u00a0chemical<\/a>\u00a0and potential human carcinogen, was found in quantities above safe drinking water levels in water wells on highly fracked landscapes. The U.S. Environmental Protection Agency says the chemical ”poses health risks to anyone who breathes the air when this compound is present.”<\/p>\n

Hildenbrand, a native of the Okanagan Valley, is a scientist (and cancer biologist by training) with the Collaborative Laboratories for Environmental Analysis and Remediation at the University of Texas in Arlington.<\/p>\n

The study, published in the journal\u00a0Science of the Total Environment<\/i>, is the first to measure groundwater quality from private water wells before, during, and after the expansion of horizontal drilling and hydraulic fracking.<\/p>\n
