C.1.2.1 DU-IS Investigation Approach

A follow-up study of the former landfill area was carried out in 2008. The investigation focused on the use of decision unit and incremental sampling investigation strategies published by the HDOH Office of Hazard Evaluation and Emergency Response (HDOH 2008b). Note that incremental soil samples are referred to as “multiincrement” soil sample in the HDOH guidance.
