Hydraulic ,fracturing, (fracking/HF) involves injecting wells at high pressure with water, proppants, radioactive tracers and chemical additives to fracture the formation and produce new cracks and pathways to help extract the gas. While chemical additives make up less than 2% of the fracking ,fluid,, this still translates to large quantities.
