I doubt that if you bought it so long ago that it is contaminated with copper because i lot of people were using it then and there was no report of copper poisoning until recently. Just test a batch running in loop in a bucket and see if that water contain copper after 12 hours and you'll know.
We should be carefull not to point every possible crash on Kent carbon, as there might be other causes. The only way to be sure is to do a test and let a cup of carbon run into a bucket and then test for copper. If there is no copper than the carbon is NOT contaminated.
