When monitoring stable priority pollutants in effluents of receiving waters, it is desirable to have a sampling method which reduces analytical work while allowing judgements of compliances to be made. A new method, called refined composite sampling (RCS henceforth), is introduced. Via a simulation study, we find that in comparison to daily sampling, RCS does achieve the above goals. Furthermore, RCS performs better than composite sampling in the sense that the combination of the relative effectiveness and the relative efficiency is higher. © 1997 John Wiley & Sons, Ltd.
