Figure 9-8. Comparison of observed and modeled tracer concentrations, for the Eagle Pass, San Antonio, and
Houston tracers, at Big Bend National Park over the duration of the study. The measured and modeled tracer
concentrations were both averaged over the K-Bar, Persimmon Gap and San Vicente monitoring sites. Error
bars represent the uncertainties of the measurements.
