For this to be a remotely legitimate study there needs to be a control, what is their control, they have none because most methyl mercury comes from atmospheric pollution, car exhaust, industrial exhaust, etc. I am sure if a turbidity test was done during the flood season it would contaminate the study with with ambient methyl mercury that continually falls to earth globally, If they said that the methyl mercury is coming from solid mercury breaking down then removing the solid mercury, which Stopher said dredges do just fine, would be logical course of action, could it be that the Salmon after eating mercury laden bait fish in the ocean are dying up river and adding to the problem year after year, I say we must then eliminate the Salmon for our children's safety, I wonder what happens to peoples intelligence, patriotism and I.Q. once they hit Gov. jobs? This study is beyond ludicrous, it is as a previous poster stated CRIMINAL in every sense, this is not just about dredging, its about how our freedoms, intelligence, money and hard work are being rapped by political greed and special interest, if we do not want socialism to be the mainstay of our life then this stuff must end....but how?....will History repeat itself?, in a true Democracy we would have an equal say in this matter, but what it comes down to is the money of special interest swaying Gov. in its favor. I also Metal Detect and the same thing is happening to this, it is being shut down, there are actually places that say anything older than 2008 is an archeological find WTF!!!!! They are giving these trust fund college lifer so called archeologist authority to take away our freedoms
.......and on and on it goes till we all fall down and the Chinese pick up the pieces.
