LA Times Covers "Sand Land," Ecological Hazards of Frac Sand Mining in Wisconsin

On Nov. 19, The Los Angeles Times' Neela Banerjee, writing from Chippewa County, WI, explained what we covered here in June in our “Sand Land” investigation.

The skinny: mining for frac sand creates a whole slew of problems and must be taken into consideration in the “cradle to grave” equation when quantifying the ecological hazards associated with hydraulic fracturing (“fracking”) for unconventional oil and gas. 

“In time, 800 acres of farmland will be mined to feed an energy boom sweeping the United States,” explained Banerjee.

The crystalline silica sand currently being mined from this farm land is blasted into hard rock shale basins during the horizontal drilling process popularly referred to as fracking. This particular fine-grained, circular sand is the perfect shape to break open up pours for shale oil and gas to flow out from under the ground.

“Ground zero for industrial sand mining is western Wisconsin, in counties like Trempealeau, Buffalo and Chippewa,” wrote Banerjee, echoing our findings here on DeSmog. “At least 60 industrial sand mines are functioning or in the permit process in the area, up from five in 2010…[A] fracked well could use anywhere from 2 million to 5 million pounds of sand.”

The airborne dust eminating from mining for frac sand, a study published by the Occupational Safety and Health Administration (OSHA) recently demonstrated, can lead to silicosis for miners working on site. Comparatively speaking, “little is known about its effect on people who live near mine sites,” Banerjee explained.
