Concentration breakthrough data collected by the USGS at Stanton, Texas during tracer injection tests of the Ogallala aquifer are simulated using an approximate and an exact analytical solution of conservative solute transport in a radial flow field from an injection well. Data were collected at selected depths in the aquifer and at fully screened observation wells. The concentration breakthrough data were simulated with the analytical solutions by finding the values of hydraulic conductivity and dispersivity which provided the best fit of the data. The exact analytical solution is the appropriate solution for analyzing data collected at the Stanton site. Both dispersivity and hydraulic conductivity vary greatly at the site. Bromide is considered to be conservative. Boron distribution coefficients are determined by using hydraulic conductivities estimated by simulation of boron and bromide breakthrough curves. Additional tracers used in the experiments at the Stanton site include aniline, phenolphthalein and benzoate.
