A method for labelling suspended solids in sewage wtih **1**4C-DDT left bracket 1,1,1, trichloro-2,2-bis(p-chlorophenyl)ethane right bracket is presented. The method allows the vertical distribution of deposited solids in a soil, following leaching with effluent, to be determined. A simple physical model which describes transport of labelled suspension through the soil is developed. This enables the conditions necessary for successful utilization of the method to be defined. Procedures for the estimation of the parameters required for the model are presented and the application of the method is demonstrated for two soils. It is shown that the method for tracing the fate of suspended solids is valid, as long as the label is sufficiently strongly adsorbed on suspended solids. It is also required that the rate of desorption of label from suspended solids be low compared with the residence time of mobile suspended solids in the soil.
