The upper map shows risk for zinc pollution and the lower map shows the risk for lead pollution to wetland. This analysis is based upon the method and results described above. Blue areas indicate land uses for which there are insufficient data to analyze.
Green areas indicate wetlands that have no risk of pollution from surrounding land uses.
These are wetlands that are surrounded by natural areas, preserves, or vacant land. The scale of metals pollution risk corresponds to a gradient of color from white to deep red. Wetlands that are white to light red in color have lower risks for receiving metals pollutants. Wetlands that are red to deep red have the highest risk. Please click on the map for a larger view.
