Analyzing isotopes to characterize natural waterSRK

The isotope content shows that the water stored in the tailings dam has evaporated, so its isotopic content is more enriched than the natural water (Figure 1). This situation allows differentiating the isotopes end members from the dam (PR3A) and natural groundwater (ABQ6A1), which will be used to estimate the natural water proportion
