Figure 4

U-matrix, four component planes, and map unit labels, from the SOM on the dioxin database. The U-matrix shows dioxin levels vary across the study area. Comparisons of the four components and labels indicate that soil dioxin contamination is limited within the 100-year flood frequency area. Very high levels of dioxin are clustered within the 10-year flood frequency area. Soil deeper than 16" below the ground is contaminated by dioxin in some areas. Dioxin contamination is alleviative in areas farther away from the river, but not linearly.
