Recently, North Carolina approved the bill to allow fracking (or hydraulic fracturing). In 2013, members of North Carolina's Mining and Energy Commission (NCMEC) are developing regulations for drilling. Drilling could begin as early as 2014.
NCMEC's chairman, Jim Womack, believes North Carolina will require "stringent disclosure laws." Many critics of fracking have shown that natural gas drilling causes earthquakes and water contamination. If North Carolina can obtain full disclosure of all chemicals used in fracking, including the "proprietary" chemicals, it would be a first nation wide.
In some situations, environmental regulators may know what chemicals are used in fracking, but there is a question as to allow emergency first responders and medical personnel know the types of chemicals used. Fracking additives can be extremely dangerous and contaminate the ground water. One of the many additives used in fracking is a compound called biocide tributyl tetradecyl phosphonium chloride. In addition to potentially harmful additives, the shale itself can release flammable and toxic chemicals like methane and benzene. These chemicals, since they are being release from the shale, can move more quickly into aquifers and into our groundwater. Hope Taylor, executive director of Clean Wate for North Carolina, says, "This is our public groundwater. The public has a right to know."
At this time, there are no water filters that remove the chemicals used in the hydraulic fracturing process. As science learns more about the proprietary chemicals used in fracking, more filters and filter systems will be able to be tested for and remove unwanted pollutants.
