Fracking for Environmental Remediation
Most of us are familiar with hydraulic fracturing as a technique used for oil and natural gas drilling. The process uses a slurry of chemicals and sand to prop open rock fissures, allowing the release of fossil fuels. However, natural gas and oil are not the only constituents trapped in rock layers; these layers can also serve as a reservoir for contaminants. At Superfund sites and other polluted areas, the process of remediation, or cleanup, can be extended and expensive. Hydraulic fracturing has been utilized as an environmental cleanup method,
