The flow of groundwater between two boreholes has been studied using radioactive Br-82 and inactive sodium fluorescein as tracers. The primary use of bromine was to determine the flow rate at the injection and the primary use of sodium fluorescein was to serve as the tracer at the system output. Either of the tracers would have been adequate for both tasks but the combined use provided an increased reliability for the test.
