Qualitative risk assessment of events that might impact water quality from chemicals at onshore shale gas wells

\n## **Abstract** \nThis dataset is used to support a qualitative risk assessment of possible events that might impact water quality and dependent ecosystems from the use, handling, and storage of chemicals and flowback at the Tanumbirini-1 and Kyalla-117 shale gas wells in the Beetaloo Sub-basin, Northern Australia.\n\n\n## **Attribution** \nGeological and Bioregional Assessment Program\n\n\n## **History** \nCollated chemical and ecotoxicity data, groundwater quality data, and supporting information for the manuscript titled “Assessment of events that might impact water quality from chemicals and flowback at onshore shale gas wells.”\r\nAppendix Supporting Information 1: Chemical assessment, ecotoxicity, and water quality data for the Kyalla-117 and Tanumbirini-1 shale gas wells.\r\nAppendix Supporting Information 2: Chemical properties, freshwater organism predicted no effect concentrations for chemicals, qualitative chemical assessment, screening risk quotients, regional water quality parameters and water quality in control and impact bores pre- and post-hydraulic fracturing at Kyalla-117 and Tanumbirini-1 shale gas wells.\r\nAppendix Supporting Information 3: Controls and management strategies and actions in relation to possible events that might impact water quality at the Tanumbirini-1 and Kyalla-117 shale gas wells.
