Trace Metals and Metalloids Present in Springwater of a Mining Area: Assessment Based on Chemical and Isotopic Data (δ2H, δ18O, 3H and 87Sr/86Sr)

The Taxco mining district is a well-known international producer of silver, jewelry, and precious metal handicrafts. Inappropriate disposal wastes from anthropogenic activities have been deteriorating the hydric resources threatening inhabitants’ health, since they use springwater for human consumption domestic activities. A multi-tracer approach combining measurements hydrochemical data, trace elements, isotopes δ2H, δ18O, 3H, 87Sr/86Sr ratios was undertaken 18 samples. δ18O δ2H indicate that comes rain had experienced some degree isotopic fractionation by atmospheric evaporation in samples at lower altitudes. 3H values on showed existence old new water. Three groups were identified according to age: local flow rhyolites, intermediate through red beds outcrop point sandstone shales, deep greenschist. results this study show utility identifying water–rock interactions paths, suggesting more widespread strontium fingerprint warranted.
