The model of Jury (1975) for estimating travel time from surface application to point of discharge for tile‐drained fields is applied to data from published studies of tile‐drain effluent concentrations and solute flux. In all systems the observed values are consistent with model calculations, and in circumstances where an exact comparison is possible the agreement between measured and predicted values is very good. Measures proposed for improving water quality by requiring standards for affluent discharge levels are discussed and criticized, and model simulations of projected monitoring policies of typical field systems are used to demonstrate the potential for misinterpreting the relationship between surface inputs and output levels.
