Abstract: Analysis of the results of repeat quantitative dye traces between a sinkhole and a spring used for public water supply were used to describe predictive relations between discharge, mean travel time, apparent ground-water flow velocity and solute transport characteristics. Normalized peak concentration, mean travel time, and standard deviation of travel times were used to produce a dimensionless, composite type curve that was used to produce a dimensionless, composite type curve that was used to simulate solute transport characteristics for selected discharges. Using this curve and previously developed statistical relations, a water manager can estimate the arrival time, peak concentration, and persistence of a soluble contaminant at a supply spring or well based on discharge and the quantity of spilled contaminant.
