Arrow understands the importance of groundwater for both agricultural and domestic use across Australia. We also understand that there are concerns in some communities about the effect of coal seam gas (CSG) drilling and production on water quality and supply.
The removal of groundwater from a coal seam is essential to release the gas stored in the seam. For this reason, Petroleum Lease holders, including CSG producers, are given authorisation under the Petroleum and Gas (Production and Safety) Act 2004 (P&G Act) to take underground water as a necessary activity in the process of extracting CSG.
The underground water rights afforded by the P&G Act are further regulated by the Water Act 2000. Arrow implements these obligations through groundwater monitoring and submission of and compliance with Underground Water Impact Reports (UWIR).
For the Surat Cumulative Management Area (Surat CMA) the Queensland Government Office of Groundwater Impact Assessment (OGIA) is responsible for developing the UWIR which assigns responsibility for groundwater monitoring and 'make good' to tenure holders.
A landholder who believes their water quality has been affected by Arrow's activities, should contact the CSG Compliance Unit within the Queensland Department of Natural Resources and Mines.
Approved underground water impact reports (UWIRs)
The Queensland Department of Environment and Heritage Protection (DEHP) requires a UWIR to be developed for each petroleum tenure where production testing has occurred or where production has commenced. DEHP approves the UWIR and then Arrow must comply with the groundwater monitoring obligations within the relevant UWIR.

Surat groundwater monitoring activity
Arrow has installed groundwater bores and undertakes monitoring across its development area. Arrow undertakes groundwater research in collaboration with the OGIA. The objective of the research is to further quantify the connectivity between the Condamine Alluvium and the Walloon Coal Measures.
This work is in addition to groundwater monitoring undertaken by Arrow in the Surat Basin, as part of its obligations under the Surat UWIR.
