High-resolution profiling of the stable isotopes of water in unsaturated coal waste rock

Characterization of the rate of water migration through unsaturated mine waste rock dumps is an essential element in assessing the chemical loading from these landforms; yet our understanding of how water moves into, through and out of waste rock is incomplete. To further understand the rates and magnitude of percolation through waste rock, deep high-resolution (every 0.1–4.5m) depth profiles of the stable isotopes of water (δ2H and δ18O) at …
