A new EPA study reported in The Hill reveals that there are approximately 700 chemicals in fracking fluid, some of which may be hazardous.
The EPA used data provided by industry over the course of two years for its study. The report incorporated over 30,000 disclosures from fracking industry professionals. Although over 700 chemicals can be found in fracking fluid, the study found that in many cases only approximately 14 chemicals are used, and of those hydrochloric acid, hydrotreated light petroleum distillates and methanol are the most frequently used.
The chemicals in fracking fluid provide functions including antimicrobial processes, improving fluid flow and protecting equipment.
Fracking fluids are not currently regulated due to a 2005 rule. However, the EPA can investigate what chemicals are in fracking fluid. At this point, the EPA is merely analyzing the chemicals and has not passed judgment on whether they should be appearing in fracking fluids or their environmental impact.
Environmental groups hope that studies such as this that fill knowledge gaps about fracking fluid components and potential environmental impact will cause more concern over fracking and the waste fluids it produces, potentially leading to more regulation.
