This annotated bibliography highlights selected research articles and other published information on the chemical composition of hydraulic fracturing flowback water, which is the fluid that flows back to the surface from an unconventional well after it has been drilled. Principle findings and the significance of each study are summarized below each source, listed chronologically by publishing date.
