Reflections on groundwaterpollution by tipping of solid wastes

Abstract

In the following paper is stated that groundwater-pollution caused by waste-tips is of very little significance. That is when is token that the waste is never dumped in open surface-water nor below the groundwater-table and that the subsoil does not contain gravel-layers nor bear ('karst"-phenomena or open fissures. Besides it appears that the leachate from a tip contains most pollution during the first years after tipping and that after two or these years this pollution diminishes gradually. The microbial breakdown of the waste and the herewith formed products play a big role in the purification-processes in the soil. Organic material is needed for the development of this microflora. This induces to the opinion to combine the tipping of certain types anorganic (chemical) waste with urban waste (high organic content) rather than to tip it separately.
