Toxic biocides may not be needed routinely at fracking sites, study shows
When oil and gas companies extract fuel from the earth via fracking, they routinely add biocides such as glutaraldehyde to the high-pressure water they use to fracture rock formations deep underground. These compounds are a preemptive strike against microbes that produce hydrogen sulfide, which can corrode pipelines.
New research, however, calls into question the across-the-board addition of toxic biocides to water used in fracking. Jason Gaspar and . . .
