«Because we extracted high - resolution stable
isotopic profiles from these shells, we were able to match them to active spells and breaks in the monsoon,» Thirumalai said.

By comparing this fingerprint to the geochemical and
isotopic profiles of 29 background surface water samples collected across the region, the team was able to determine where and to what extent contamination associated with brine spills had occurred, and rule out the possibility that it had been caused by other sources.
