(f) the Iscation of the ground water sampling wells should be deteralmed by a hydrological analysis of the potential movement of seepage from the tallings disposal area. In general, the objective is te place maatter wells in all directimas around the taillags area with the engdsasis on the dawa gradient localleas.
