This study investigates the connectivity of heavy metals in ground water and heavy metals that exist in marine sediments and seawater. Six metals (As, Hg, Cr, Pb, Cu and Fe) in coastal areas in Tugu Semarang were examined. The se metals were found ini marine sediment, groundwater and sea water in coa s tal areas. The re is gradual decreased of the metal concentrations in sediment, sea water and groundwater, and the highest concentration of metals was found in marine sediment and the lowest in coa s tal groundwater. The connectivity of metals in marine sediment, groundwater and sea water predicted due to changes in pH and salini t y of sediment and water. The increasing number of reclamation, waste water disposal from industrial and urban areas may has caused the increasing of heavy metals concentration i n the coastal areas.
