My reply to this individual that can't find the bravery to identify him/herself is simply this.<BR/><BR/>"Heavy Metals" as I most carefully defined, are those elements that are more dense than their surroundings. If it is more dense/heavier, than the water that it is in, then logic suggests that this stuff doesn't just float merrily down stream like so much flotsam. <BR/><BR/>This is where the great lie resides.Bay Viewshttps://www.blogger.com/profile/16760942927620035881noreply@blogger.comtag:blogger.com,1999:blog-10432089.post-44787266228047779242007-03-15T07:25:00.000-07:002007-03-15T07:25:00.000-07:00Heavy metals of concern in our watershed are prima...Heavy metals of concern in our watershed are primarily lead, cadmium, zinc, arsenic. Contrary to your comments, most of these trace or heavy metals are results of past mining and processing in the Silver Valley, not natural erosion. <BR/>Also must clarify that these metals do not filter down to "bedrock" in the bottom of Lake CDA. They are deposited as a well defined layer of sediment at or near the top of the lake bottom where, depending on oxygen levels in the deep waters, these metals can migrate back into solution in the water column. This chemical process is why management of the lake's water quality, specifically oxygen levels,is critical.Anonymousnoreply@blogger.com
