1. IMPROVING SITE CHARACTERIZATION Rhode Island’s Perspective IMPROVING SITE CHARACTERIZATION Rhode Island’s Perspective Overview by Leo Hellested, P.E. Chief RI DEM Office of Waste Management 6-6-02

2. I.Goals/Objectives Programmatic Goal: To minimize or eliminate the impacts and risks to human health and the environment which result from releases of oil, chemicals or wastes.Programmatic Goal: To minimize or eliminate the impacts and risks to human health and the environment which result from releases of oil, chemicals or wastes. Site Characterization Objective: To accurately assess the nature and extent of contamination, including its mobility, toxicity and volume, such that the actual or potential impacts of the release may be evaluated and addressed.Site Characterization Objective: To accurately assess the nature and extent of contamination, including its mobility, toxicity and volume, such that the actual or potential impacts of the release may be evaluated and addressed.

9. V.Ongoing Efforts on Technical Issues: RIDEM recognizes the benefits of gathering larger data sets, even with less QA for individual data points, to better characterize site contamination.
