The method includes capturing or retrieving the ,flow back, from the well following the ,fracturing, operation. The ,flow back, or other source water is introduced to an electrocoagulation (“EC”) treatment process. EC treatment separates the water from other ,fracturing fluid, components in the ,flow back, and also removes bacteria and other contaminants.
