Specifically, recovery of pit water from well drilling operations and hydraulic fracturing could reduce the impacts associated with wastewater transportation, deep well disposal, and fresh water procurement for subsequent hydraulic fracturing operations.
This study evaluates the environmental and economic impacts of FO for treatment of O&G pit water through comparative life cycle impact and costing assessments; the FO technology is evaluated when operated as an engineered osmosis system and as a stand-alone osmotic dilution process.
Opponents, including California's Democratic lawmakers, have termed the bill a water grab that would circumvent state law, pit water users against each other and roll back environmental protections.
