Can Waste Water Be Disposed of Safely?

The Nature of ,Flowback, Water. Even if fresh water is used as the base ,fracturing fluid,, what returns to the surface is salty. This is because the water found in association with hydrocarbons has high salinity. Shale oil and gas ,flowback, water salinity typically range from 16,000 parts per million (ppm) to more than 300,000 in some instances.
