Well there are about 10.3 trillion gallons in lake mead, so the Colorado spill is insignificant.
10,300,000,000,000 gals / 10,000,000 gals = 1 part in 1,300,000
It is not the parts per million with heavy metals. It is the accumulative effect. Keep drinking it and it adds up to some pretty serious health problems.
Maybe it is minute, thats fine. But would you purposely drink mercury, arsenic, cyanide?
Now to be sure, there are some of these naturally within that Lake. But why in the hell would anyone accept this as a result of an agency that force themselves upon the American citizen daily through its ideology?
Yes it will settle out in time. But who pays for the health effects of those effected as a result of this debacle?
Remember the Downwinders?
