Photographs from the Passaic R.

The Passaic River is one of the most developed and polluted rivers in the USA. These photos were taken in the lower

Passaic where the distinctive odors from the various factories provide sufficient navigational information. The familiar smell of

sewage, the rotting corpse smell of the fat rendering factory, and the butterscotch fragrance used to cover up the scent of some

factory emissions all mark distinctive locations along the river. The Diamond Shamrock site where Agent Orange was produced

is the origin of much of the sediment’s elevated concentration of dioxin. Our study was to determine the effectiveness of dredging

of the contaminated sediment to remediation of the river.
