Fluids used to extract coal seam gas are unlikely to contaminate underground water stores, a Queensland parliamentary committee has heard.
Environmentalists fear aquifers could be tainted by chemicals used in an extraction process called fracking.
But Dennis Bird from the Department of State Development, Infrastructure and Planning says most chemicals used in the process can be bought at supermarkets and hardware stores.

Fracking involves pumping a mixture of sand, water and chemicals underground to force coal seams apart, allowing the gas to be extracted.
