Focused on dry-land soils Future site development
Residential Commercial/industrial
Divided property into ½ acre grids Current distribution of contamination in soil Some off-site soils Other pathways
Fish and shellfish Marsh Groundwater

Health Evaluation
Used average concentration per grid Estimated exposure doses for children,
adults, and workers Compared these doses to health guidelines Compared these doses to human and animal
studies Described possible harmful health effects Identified ½ grids that are a health concern
For residential use For commercial or industrial use
12
Dark and medium blue grids concern for PCBs in soil
13
Dark blue grids concern for mercury in soil
14
Dark and medium blue grids concern for lead in soil

About 30 acres health concern for residential use 65 half-acre grids
About 5 acres health concern for commercial or industrial use 9 half-acre grids
