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.

## **摘要**
本数据集用于支撑针对澳大利亚北部比塔罗坳陷（Beetaloo Sub-basin）内Tanumbirini-1与Kyalla-117页岩气井在化学品使用、装卸、存储以及返排液过程中，可能影响水质及依赖型生态系统的各类潜在事件开展定性风险评估的相关工作。

## **数据沿革**
本数据集整理了题为《陆上页岩气井化学品与返排液对水质的潜在影响事件评估》（Assessment of events that might impact water quality from chemicals and flowback at onshore shale gas wells）的论文所涉及的化学品与生态毒性数据、地下水水质数据及辅助支撑信息，具体包含以下3份附录支撑材料：
附录支撑材料1：Kyalla-117与Tanumbirini-1页岩气井的化学品评估、生态毒性及水质数据；
附录支撑材料2：Kyalla-117与Tanumbirini-1页岩气井的化学品属性、化学品对淡水生物的预测无效应浓度、定性化学品评估、筛选风险商值、区域水质参数，以及水力压裂前后对照井与影响井的水质情况；
附录支撑材料3：针对Tanumbirini-1与Kyalla-117页岩气井可能影响水质的各类潜在事件的管控措施、管理策略及行动方案。
