The report sets out the work undertaken by the Inquiry to date in assessing the impacts and risks associated with any potential onshore unconventional shale gas development in the Northern Territory. The report explains the method by which the Inquiry proposes to gather and then assess the evidence relevant to the issues that have been identified and discussed with the public. Where appropriate, the Interim Report makes some preliminary assessments about the likelihood of some of those risks eventuating as well as the methods to mitigate the risks. Finally, the report de4scribes the future work of the Inquiry that will be undertaken prior to the release of its draft Final Report by the end of the year.; Made available via the Publications (Legal Deposit) Act 2004 (NT).
The Inquiry is Chaired by Justice Rachel Pepper. The panel comprises 10 eminent scientists across a range of disciplines. Includes bibliographical references : pages 161-170. Publication spans 2017-2018; Made available via the Publications (Legal Deposit) Act 2004 (NT).

BACKGROUND AND ISSUES PAPER 20 February 2017 16 7.1. Water Table 7.1 lists the possible risks that the hydraulic fracturing of onshore unconventional shale reservoirs and its associated activities may have on water resources (surface and groundwater), including aquatic ecosystems and biodiversity, in the Northern Territory Value Risk Water quality Groundwater There may be a risk of groundwater contamination as a result of: induced connectivity between hydraulically fractured shale formations and overlying or underlying aquifers; surface spills of chemicals, flowback water or produced water into near-surface groundwater; leaky wells as a result of poor design, construction, operation or abandonment practices or as a result of well degradation over the life of the well; re-injection of flowback water, produced water or treatment brines into a groundwater aquifer; and/or induced connectivity between different groundwater systems as a result of seismic activity caused by hydraulic fracturing or reinjection of water. Surface Water There may be a risk of impacts on surface water quality as a result of the following types of incidents: on-site spills, including as a result of extreme weather events such as cyclones and floods; spills that occur during transportation of chemicals to or from the site during the development and production phases; and/or spills of flowback water, produced water or brines produced by water treatment. Water supply and distribution (quantity) There may be a risk of adverse environmental impacts (including those listed in this table) as a result of reduced water supply due to the large amounts of water being extracted for use in hydraulic fracturing. There may be a risk of changes to the timing and/or quantity of surface water flows because of the discharge of produced water, which may be significant particularly in arid to semi-arid landscapes. There may be a risk to surface water and groundwater flow processes as the result of possible seismic activity caused by hydraulic fracturing or reinjection of water. Aquatic ecosystems and biodiversity There may be a risk of adverse impacts on aquatic ecosystems and biodiversity, including groundwater dependent ecosystems. This may result from changes in the quality and/or quantity of surface and/or ground water available to them.
