REVISED CREEK SEDIMENT & FLOODPLAIN SOIL INVESTIGATION

Five years of Ministry of Environment investigating and studying of the Canagagigue Creek sediments and floodplain and now we allegedly need even more "investigation", this time by Chemtura/GHD. For the love of God Chemtura/Lanxess stop screwing around and start removing Dioxins, DDT, PCBs, Mercury and BNA extractables. Sediments move both by suspended sediment transport as well as by erosional and depositional forces. Is this your and the M.O.E.'s game? Study for six or seven years and then due to seasonal flows and heavy storms start the whole process over again because of changes in the contaminant's location?

The Ministry made their biases very clear with their oversampling of the New Jerusalem Rd. area and under sampling of further downstream sites. Chemtura's latest sampling locations appear to be covering some of those downstream sites. That said they keep repeating that samples will be preferentially collected from depositional areas. All these decades and to date they haven't figured out exactly where those depositional areas are? Really?

Another issue is their homogenizing of sediment or soil samples. It was David Hofbauer at the last TAG meeting who suggested that this is a good way to "average away" issues. If you have a couple of preferential flowpaths for example of dioxins and DDT but you sample a large enough area around them you can reduce the concentrations found by the number of zeros for other areas that you include in your calculations. Gamesmanship is alive and well in environmental "investigating".

Access agreements have not yet been acquired for some of the downstream floodplain sampling. Likely this will also provide Lanxess/GHD with further delays and time extensions.

Nearly thirty years of "investigations", monitoring and sampling with always minimizing through various means; and I have zero confidence in their credibility, ethics and honesty. Games and delays is what the story has always been. It's 2017 and the authorities and guilty parties have known since the 80s and 90s as to what the problems were in the creek and where they are located. Get at it!
