The International Committee for Anthropogenic soils (ICOMANTH) was formed in 1995. In 2005, ICOMANTH published circular letter 6 which defined new terms for describing and sampling human-altered and -transported soils. Following circular letter 6, ICOMANTH is seeking input concerning the addition or definition of new terms for anthropogenic surface features and anthropogenic subsurface features. In addition, ICOMANTH plans to propose new US Soil Taxonomy family-level categories that deal with human safety, particle-size class, and mineralogy, especially for soils containing significant amounts of non-toxic manufactured materials. Finally, a collection of soil series that identify human-altered or transported soil materials will be gathered and separated into classes for possible inclusion in US Soil Taxonomy.
