New Tracers Can Identify Fracking Fluids

Alexandria, Va. — Hydraulic fracturing, the natural gas extraction method known popularly as fracking, has been controversial in large part to the concern about groundwater contamination by the fluids used in the process, especially the so-called flowback fluids that re-emerge at the surface from fracking wells and are usually disposed of by waste water fluid injection into other formations. Now, researchers have developed a geochemical method of identifying fracking fluids in the environment. The tool could be used to identify hazardous spills in the future and may even lead to better use and disposal of fracking wastewater.
Read more about how scientists came up with the new tracers and what they might mean for wastewater disposal in the February issue of EARTH magazine:
The American Geosciences Institute is a nonprofit federation of 50 geoscientific and professional associations that represents more than 250,000 geologists, geophysicists and other earth scientists. Founded in 1948, AGI provides information services to geoscientists, serves as a voice of shared interests in the profession, plays a major role in strengthening geoscience education, and strives to increase public awareness of the vital role the geosciences play in society's use of resources, resiliency to natural hazards, and interaction with the environment.
