Hydraulic Fracturing and its Impact on Water Resources
Hydraulic Fracturing and its Impact on Water Resources

After the ,fracturing, process, a percentage of the water returns fairly quickly to the surface as ,wastewater,, also called “,flowback,.” The briny water that has long been underground and comes up during continued operation of the well, called “produced water,” can contain naturally occurring contaminants like the radioactive element radium, along with other heavy metals and salts.
