CONCERNS have been raised that a coal seam gas project in the north-western NSW town of Narrabri is polluting a creek that runs into the Murray-Darling Basin.
Water samples, seen by The Australian, have revealed abnormally high levels of methane and ammonia in a shallow creek which is connected to the Namoi River and the Murray-Darling Basin.
The Narrabri Coal Seam gas project, which Santos last month acquired from Eastern Star Gas, has permission from the NSW government to discharge treated CSG water into the Bohena Creek.
Water samples taken from the point where the treated CSG water is discharged into the creek, show elevated levels of methane, carbon dioxide, and cyanide.
The samples were collected by on behalf of environmental group Friends of the Earth and analysed by ALS Laboratory Group.
The results were reviewed by the community-based group National Toxics Network, which found the levels of ammonia and methane at the point where the treated CSG water were "of concern". The level of ammonia was three times higher than the Australian drinking water guidelines at the point where the CSG water ran off into the river system.
