Conclusions

• Sediments have high pH and natural fertility• Sediments have high soil moisture storage

capacity• Sediments have somewhat elevated levels

of metals in some cases• Plants grown in sediments do not have

significantly elevated metal levels• After dewatering and weathering, sediments

should make productive agricultural soils
