The ability of organic matter to form stable complexes with metal ions has been well established. The image shown to right is a 1995 SPOT satellite image overlaid with National Wetlands Inventory wetland polygons that have been color coded to reflect the results of the analysis. Yellow areas indicate wetlands that have a low capacity to sorb micronutrients or heavy metals. Pink areas indicate wetlands that have a moderate capacity to sorb micronutrients or heavy metals. Red areas indicate wetlands that have a high capacity to sorb micronutrients or heavy metals.
Blue areas indicate wetlands for which there are insufficient data to analyze.
Please click on the map to see a larger view. Those wetlands that rate as moderate to high in capacity may be particularly important in protecting water quality in the region. Because these wetlands have some ability to moderate micronutrient or heavy metal levels, they are most likely providing important water quality benefits to waters that flow from or through them.
