A chemical transport model, CMLS, and a weather simulation modal, WGEN, were coupled to investigate the impact of possible and equally likely weather sequences on the travel time and relative amount of various chemicals penetrating given depths into the soil profile. Several combinations of geographical locations and soil chemical properties were investigated. Considerable variability in travel time from one weather sequence to another resulted. This variability is expressed in the form of probability distributions. Implications of this variability in terms of monitoring programs, the interpretation of model studies, and regulations on agricultural chemicals are discussed.
