By their very nature, pipeline surveys are typically long and narrow. As such, pipeline corridors traverse differing landforms and the potential for archaeological sites varies with each landform construct. Understanding where potential archaeological sites may exist on the landscape assists planners in the development stage of the pipeline route.

With a thorough understanding of soil development and spatial Geographic Information System (GIS) mapping, CHC can assist pipeline officials when they are required to conduct an archaeological survey prior to line installation. In addition to conducting pipeline surveys throughout the Midwest, CHC is a certified archaeological firm with the Iowa Rural Water Association.
