The Post Tribune is reporting today that IDEM does not consider the clumps found on the beach a few weeks ago to be of any toxic substances, and only very small traces of mercury were found. See the article below:

Also, to help you understand the Indiana 303d Impaired Waters list, below is more information.

With respect to the presence of mercury, it’s primarily fish consumption that you really need to worry about. Mercury in lakes and rivers is converted into methyl mercury by certain bacteria. Fish ingest methyl mercury by swimming or feeding in contaminated water. Methyl mercury accumulates in fish tissue and is carried up the food chain to larger fish, animals and humans. Mercury is bioaccumulative in organic systems, which means that mercury ingested by an organism will remain in the body.
