The level of the chemicals found at Arrow's operations ranged between two parts per billion (ppb) and 16ppb.

The Queensland Department of Environment and Resource Management will now study the bores to determine if the level of chemicals is naturally occurring or introduced by the company.

Arrow Energy said the shallow monitoring bores have no connection to gas production and the aquifer is not used for stock or domestic water.

The find is the latest of a string of contaminations in Queensland's CSG industry.

In November last year, the chemicals were found in three of Arrow Energy's CSG wells at Moranbah in central Queensland.

Also last year, Cougar Energy's pilot underground coal gasification plant near Kingaroy was shut down by the state government after benzene and toluene were found at just two parts per billion in nearby bores.

Drew Hutton from Friends of the Earth said the level of chemicals at Arrow's operations was considerably higher than the level at which Cougar was shut down.

from Sydney morning herald. Imo QlD government have backed themselves into a corner, once again. It will be interesting to see the outcome of this.
