In updating its Information Guidelines (2018) the Independent Expert Scientific Committee on Coal Seam Gas and Large Coal Mining Development (IESC) identified the lack of use of environmental tracers in developing conceptual and numerical models and how they can be used in a risk context to reduce uncertainty.
Confidently identifying and evaluating causal pathways to impacts on water-assets is key to an efficient environmental assessment process. Environmental water tracers can often complement other techniques and offer an important means of gaining multiple lines of evidence to support conceptual models. Importantly, in some situations tracers may be the only feasible way of gaining information about systems at appropriate spatial and temporal scales. This presentation will provide an overview of the IESC’s environmental tracers factsheet, by explaining how tracers can be used in environmental impact assessments by:
