Hydrochemical Compatibility Assessment of Aquifer Injection of Treated Coal Seam Gas Water into Surat Basin Aquifers

Aquifer injection is being identified as an option for the management of coal seam gas (CGS) water in Queensland. The feasibility of aquifer injection will depend on a number of issues, including the ability to manage any potential risks to the environmental, economic and social values of the receiving aquifers. A hydrogeochemical assessment to assess the compatibility of re-injection of pure reverse osmosis (RO) permeate and RO permeate / CGS water blends into different target aquifers forms part of the approvals process.
