In this study, the phased approach is used to expedite collection of data and information about the site. The approach consists of sampling soils and sediments at a variety of locations, using applicable sampling devices. The validated analytical measurements acquired from sampling is entered into a database. This data then can be applied in a geographical information system (GIS). Further analysis of material can be reduced and saved in the database. The chain-of-custody records throughout the phased approach ensures careful and accurate documentation.
