Magdalena River is a superficial water body from Colombia, which flows into the Caribbean Sea. Dragging with it elements with diverse chemistry nature throughout the watercourse. Similarly, one of its most flowing current arm of the river, known as the Dique Channel, capture minerals, organic matter, clays and metals. Both Magdalena River and Dique Channel finally slop their water stream into the coast of Barranquilla and Cartagena bay, respectively. The presence of metallic species in dynamic aquatic structures e.g., rivers) and coasts that interact inwardly (sediments-atmosphere-water) triggers variations on the densities from heavy metals existing onto the water. Due to the heavy metal fluctuations given in estuary and marine systems, the annual behavior of Pb, Cr, Cu and Total Hg from Dique Channel was determinate during 2006-2010. The aim of this study is to complement the tracing made by the North University on 2006 and the information related to heavy metals and reports of the physical-chemistry variables given by the Dique Channel Regional Autonomous Corporation-CARDIQUE by means of its participation in the Network for the Monitoring of Environmental Quality of Marine Program-REDCAM. One of the main contributions of the present study is the purpose of control solutions to mitigate the presence of unacceptable concentrations of heavy metals that can jeopardize the flora and fauna from the impacted ecosystems. Results obtained shows that the Canal del Dique drags heavy metals in high concentrations, which can affect dramatically the intern Bay of Cartagena de Indias.
