Groundwater is purified by a process in which solid constituents are first separated off, dissolved organic compounds are adsorbed to an adsorber resin, the adsorbed organic compounds are desorbed using steam and the adsorber resin is regenerated using an acid. The process makes it possible to separate aromatic and halogenated hydrocarbons off from heavily polluted groundwater to the extent that the groundwater can be added to flowing surface water without reservation. The purified water can, if appropriate, be used as cooling water or after further biological purification, also be used as drinking water.
