Groundwater δ18O and δ2H for NSW, Australia: New data from DCCEEW, ANSTO and CSIRO.

This dataset contains 1166 new data points for stable water isotopes (δ2H, δ18O) in groundwater for NSW from a 2021 NSW Department of Climate Change, Energy, the Environment and Water (DCCEEW, previously DPIE) statewide groundwater isotope survey, NSW, Australia, supplemented by other unpublished data from ANSTO, CSIRO and DCCEEW/DPIE. 

This data is described in: Cendón, D.I., Hankin, S.I., Crawford, J., McDonough, L.K., Hughes, C.E., Meredith, K.T., Kelly, B.F.J., Harris, S.J., Raiber, M, Gray, S.S., Green, R.T., d’Hautefeuille, F.B., 2025.  Groundwater δ2H/δ18O isoscapes for New South Wales (Australia), Journal of Hydrology: Regional Studies. https://doi.org.10.1016/j.ejrh.2025.102732.
