What is going on here?
 

This is a picture from Wisconsin, (Baileys Harbor) I don't know what they are doing. I am sure someone on here knows.Thanks, KN

I am guessing that it is something to do with dredging the harbour for boat slips, here is a more recent picture

Aren't those huge water bladders laying on the ramp? Maybe they are shipping in some fresh water from down south.:D Someone knows the answer.. KN

I've heard that EPA requires retention and disposal of bottom soils that contain pollutants. Alot of places are not dredging due to the potential for disturbing things like mercury and pcb's that settle and stay forever. Big problem on the lower Great Lakes.

That would be my guess, they pump the slurry in to the bladders and let the water drain off and remove the waste left over.

I think they might be storing the dredge material in porous bladders, so as not to pollute the harbour, just a guess though.

I see some others posted whilst I was thinking about the problem, here is the phone number for the marina if any one wants the definitive answer:drink: 920-839-9778

Thanks for the replys Chris and Wobble. How would you think they are going to dispose of those bladders? To me they look too big to crane onto a semi. (too wide) KN

Pump into tankers for transport. Most likely they would do a partial remediation on site- like dewatering.

They are doing something similar on Little Lake Butte Des Morts, but it's cleaning up PCB contamination. After the bladders are dewatered, big backhoes come in and simply carve up the bladders and are hauled to the landfill. Bailys harbor might be part on that Superfund project also.

THey are beer bladders used to hold massive amounts of beer for a Dock party :ernaehrung004:
