The saddest thing of all about Combie and the future of Mercury remediation is that non evasive, natural, permanent processes exist, processes that enhance and work with the natural processes already in action. Processes they refuse to acknowledge, yet history overwhelmingly supports. Systems that don't transfer waste from one location to another, or create additional waste streams and cause undo destruction to the lake bottom and surrounding habitat by invasive mechanical means. There are proven treatment techniques allready in use, such as Phytoremediation, Bioremediation, algae biomass curtains, etc. Why not spend a fraction of the millions they're getting on establishing a few algae biomass curtains that simply float around the reservoir naturally remediating as they go. They can be easily cultivated or maintained and the waste recyled into livestock feed and natural fertilizers. Or introduce plants whose cell structures naturally attract heavy metals- heck, might as well get a few other bad boys out besides mercury. You know why they say these won't work? CAUSE IT WONT CREATE AN ONGOING REVENUE STREAM FOR THEM! Instead they are gonna take a lap or two around the lake chewing up the lake bottom as deep as those cutter head teeth will reach, catch what little Mercury they may, collect a check and move on to the next body of water and pile o' gold. Every few years, about the amount of time it will take for the lake bottom to recover they'll comeback around saying it needs to be done again. They couldn't have picked a more inefficient, environmentally unfriendly method or financially burdensome process. And they are the ones being called "GREEN". I call B__L S__T! Mother Nature is far more adept at and capable of cleaning up the environment than the self proclaimed environmentalists ever will be, but they are too idealistic, greedy, and egotistical to truly care or see it.
I bought the domain name CaliforniaPCBRemoval.com and started researching how to get equipment like centrifuges that clean dirt lol. My weird dream was to somehow be able to support myself and put dredgers to work but the more I talked to actual scientists and enviro engineers the more I realized it really messes up a fairly pristine area unless it is really needed. I strongly encourage those interested in this subject to see what they are doing or did in New York to remove the PCB's from factories up the Hudson many years ago. Maybe it was needed there I don't know but I thought it seemed a viable way to help the environment and dredge on a very large scale but the more I looked into it the more I saw it wasn't really the best thing to do. In the end it makes no sense because the pure scale of clean-ups like this are hugely expensive and are essentially sanitizing dirt which do you really want to see happen or is it really needed at Yankee Jims? (just an example of an area technically high in PCB's) As mentioned in the comment above mine nature will figure out a way.

ban the dredge so Sierra Fund can make millions dredging none existant mercury contaminent in reservoirs SIC SIC SIC INSANE (*&^%$#@---John PS. Latest scam with Fleck/Alpers boyz is the whole delta is FULL of killer mercury so they want to flood the delta with flocculants and collect all that nasty natural mercury even though NONE in wildlife chain but they know it's there ...my god billions to kill the delta. Oh well won't matter as once Jerrys tunnels are dug to steal all the water the ocean will ingress, salinate and kill it all YAHOO. What a cluster *&^%
