Furthermore, Underground Injection Control (UIC) requirements under SDWA should be extended to ,hydraulic fracturing, operations regardless if diesel fuel is used as a ,fracturing fluid, or not. One of the biggest barriers that hinder the advancement of our knowledge on the ,hydraulic fracturing, process is the lack of transparency of chemicals used in the practice.
