Chloride/bromide ratios as a natural tracer of urban runoff in the Tucson basin, Arizona
The weight ratio of naturally occurring chloride and bromide (Cl/Br) can be used to identify water origin, and as a tracer. In the Tucson basin, where geologic inputs of these constituents are limited, the mean Cl/Br ratio of uncontaminated ground water is 130. This ratio may be altered by artificia...
