Lithologic Description.  

Lithologic descriptions and classifications of cuttings and cores from bore holes and test pits are captured in ERPIMS.   Each record describes a distinct lithologic interval.   Records for all of the strata at a given location must relate to the stratigraphic column for the installation.  The optional fields (Stratigraphic Unit and Hydrostratigraphic Unit) should be provided unless that information is not available.  Use the VISDESC field to augment the LITHCODE field by describing any secondary characteristics including color, formation name, and other descriptive lithologic information.  Test results of soil/rock properties (e.g., soil plasticity) should be entered in the VISDESC field and not in the chemistry tables.
