Abstract
Methods for increasing hydrophobicity of native water-bearing zones or aquifers comprising the step of permanently embedding non-degradable, solid colloidal materials formed to have a particulate size of less than 10 microns. Exemplary materials include activated carbon, zeolites and hydrophobically treated clays. The particulate colloidal materials are coated with an agent to facilitate their distribution, including anionic polymers, chelating agents or combinations thereof. The materials are applied preferably by low pressure injection and are particularly effective at containing the migration of hydrocarbon contaminants, typically present as a plume, for at least several decades.
