The Waterloo Region Record carried an excellent story titled "Mercury still leaking near Grassy Narrows" on March 1/17. In going on-line in order to provide a link to it I found numerous stories on Grassy Narrows just not this specific one.

There is both evidence of new mercury still leaking into the river as well as old mercury still held in the river sediments and being bio-accumulated in the fish which the community live on. It makes you wonder how likely the Ontario M.O.E. are to clean up our Canagagigue Creek in Elmira which has contaminated carp, suckers, shiners, chub and minnows if they won't clean up a river system which has contaminated walleye and other sport fish being eaten by both natives and tourists.

Another article published in the Record last July 4/16 was titled "Province ignored minister's 1984 recommendation to clean up mercury in river near Grassy Narrows". This article indicates that mercury has spread at least 100 kilometres downstream in the English-Wabigoon river system. This lets us know that indeed Dioxins/Furans, DDT, PCBs and mercury in Lake Erie are coming from Chemtura Canada in Elmira as well as possibly other closer sources. A couple of remediation methods other than the obvious dredging options are also indicated in this article.

Back to the first article mentioned above there are many things to be learned relevant to Elmira and Chemtura. Firstly the sediment levels still being so high after decades of alleged non-dumping, non-leaking is unlikely. Secondly mercury can travel via groundwater. Interesting as Chemtura have long wrongly refused to admit that possibility for Dioxins and DDT, under any circumstances. Thirdly plain, ordinary removal or dredging is a real option for remediation.
