re: Safe to eat catfish caught in the Mississippi River at BR south of Exxon?

I requested and received a chemical and metals analysis from our local water association about 4 years ago. I was surprised to find trace levels, (ppm) of chromium, lead, mercury, molybdenum, arsenic and other chemicals in our drinking water. Several of these chemicals are water treatment chemicals and are definitely harmful at some level. I called the Association to ask how chromium was in our drinking water but no one seemed to know much. We drink a lot of bottled water now.
