The disclosure relates to a method of seepage control which comprises contacting a soil surface with a composition comprising anionic copolymers and a surfactant. Particularly disclosed is a method of seepage control in water holding or transport earthen containers which comprises contacting a soil surface with a composition comprising an anionic (co)polymer and a surfactant, in which the anionic polymer is in the form of an aqueous solution, and the anionic (co)polymer is formed from 50 to 95 weight% anionic monomer(s). This method is suitable for seepage control in irrigation ditches, drainage ditches, farm ponds, feeder canals, golf course water features, park ponds and lakes, lagoons, and the like.
