Tracer Tests

Tracer tests are methods used to study how water moves through underground or environmental systems. A safe, detectable substance—called a tracer—is introduced into the water source. By monitoring where and how quickly this tracer appears downstream, scientists can determine flow rates and pathways, identify wells' connection to certain aquifers, or detect contamination spread. These tests help manage water resources, ensure environmental safety, and plan effective remediation strategies, providing vital information about subsurface water movement without disturbing the environment significantly.
