Landowners in the Mid West are demanding tighter regulations be imposed on one of the processes being used to extract shale gas.
Hydraulic fracturing or 'fracking' is used by the gas industry in the extraction of coal seam, shale or tight gas.
It involves injecting chemicals, water and sand at high pressure into rock formations.
The process has been controversial in the eastern states and has been banned in France and some US states over concerns it could contaminate aquifers and drinking water supplies.
The Department of Mines and Petroleum has given three companies approval to carry out the process at gas wells near Dongara, Jurien Bay and Eneabba.
Eneabba resident Wendy Mills wants tighter regulations imposed on the industry.
"We're extremely concerned because some of the chemicals that they're using," she said.
