Social Impacts of Industrial Silica Sand (Frac Sand) Mining: Land Use and Value By Mark Krumenacher and Isaac Orr* Fourth in a series #137 (May 2015): Environmental Impacts of Industrial Silica Sand (Frac Sand) Mining #138 (June 2015): Economic Impacts of Industrial Silica Sand (Frac Sand) Mining
Sand is critical to fracking. After workers drill down into rock, they create fractures by pumping in a mixture of water, chemicals and sand. The sand keeps the cracks propped open so that oil and gas are released. Frac sand mining creates significant air pollution from the handling, mining, and processing of the sand.
