These distillates include kerosene, mineral spirits and a number of other petroleum products that often contain high levels of benzene, a known human carcinogen that is toxic in water at even minuscule levels. Drillers inject these substances into the earth under extremely high pressure in a process called hydraulic fracturing that energy companies use to extract natural gas and oil from underground formations.
