The objective of the site characterization should be to identify and locate, both horizontally and vertically, significant soil and rock types and groundwater conditions present within a given site area and to establish the characteristics of the subsurface materials by sampling or in situ testing, or both.

ASTM D – Guide to Site Characterization for Engineering, Design, and Construction Purposes

This guide refers to ASTM methods by which soil, rock, and ground water conditions may be determined. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase dd420 reduce significant digits of reported data to be commensurate with these considerations.

The objective of the investigation should be to identify and locate, both horizontally and vertically, significant soil and rock types and ground water conditions present within a given site area and to establish the characteristics of the subsurface materials by sampling or in situ testing, or both.
