Mercury Contaminant Map Mercury Contaminant Map with ½ Acre Grids 11

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 15
