　　Recently DuPont, Nanjing University and BCEG began collaborative work at a former chemical manufacturing site in Nanjing City, China.The goal was to use this as a pilot ortest site to conduct a remediation project.The relatively small former chemical manufacturing site is located adjacent to other chemical manufacturing operations, roadways, a housing development, and community vegetable gardens.Since the project began, old buildings have been razed, several phases of soil and groundwater sampling have been completed, and that work has provided data sufficient to build apreliminary conceptual model and to conduct a screening-level human health risk assessment.While contamination in surficial and sub-surface soils appears to be relatively limited, some contaminants have been found in groundwater samples.
