Fights over river dredging
hanc...@bbs.cpcn.com
article illustrates the challenges of the transportation industry.
As best as I can tell, the dredging is a good idea and there is no
adverse environmental impact.

It disturbs the ecology of the river bottom where dredged, and it
produces several million cubic yards of material that has to be
deposited somewhere else. Certainly there are major environmental impacts.

delayed it so much as to make the river almost unnavigable. There was
concern that dioxins and other nasties were in the silt on the
bottom. They had to build a special landfill for the waste; the
township fought to not have it in their back yard.

Depends on where the dredging waste goes. Also just stirring up all
the muck on the bottom can release interesting substances, heavy
metals, etc.

What heavy metals? As far as I know, the river bottom is just plain
dirt. It's not like a nuclear plant was on the river bottom at one
time.

umm 100+ years of heavy manufacturing along the Delaware R produced a
lot of toxic waste that was dumped in you know where
for many years unfortunately all rivers were used as dumping grounds
good example, GE and the Hudson R

Metals such as arsenic, cadmium, cobalt, chromium, copper, iron,
mercury, manganese, nickel, lead, tin, and thallium, and others.
River sediments can act as sinks for a wide range of contaminants
including heavy metals from various sources (e.g. industrial and waste
water discharges).

Dredging is always a big environmental concern; it's hard to determine
what is buried in the muck, you've got to put it somewhere and account
for runoff from that location, and determine if there's any disruption
of existing plants and animals in both the dredged area and the
disposal site. There may be none of the above in this location, but
all the checks and studies still have to be conducted.

There have been fights over Crooked Creek in Arkansas for many years. One of
the main concerns has been how dredging would affect fishing along the creek.
Last I heard (and it's been a while), a compromise of sorts had been reached.
