- Environmental Conditions. Saltwater is a little bit abrasive so that it can dissolve metals faster compared to freshwater. On the other hand, the river has fast-flowing waters that can produce friction, which could speed up decay. Ponds and lakes have a slower decay process because of their slow-moving waters.
