MORE INFO REGARDING LANXESS MARCH 2021 "PROGRESS REPORT"

Back on April 20/21 I posted here about the on and off-site pumping wells and how inadequate, especially the off-site pumping was. Today we will begin with Table A.4 and the concentrations in water of just a few Uniroyal Chemical industrial contaminants more than thirty-one years after the Elmira "Water Crisis" of 1989. In the Upper Aquifer at monitoring well UA 560I we currently have the following: Chlorobenzene at 622 parts per billion (ppb or ug/l) dissolved in the groundwater along with Toluene at 7,320 ppb. 0-Xylene is at 109 ppb and m/p xylenes at 162 ppb. Accompanying those toxins we have 2-Mercaptobenzothiazole (480 ppb), Aniline (400), Benzothiazole (1360) and 2-Chlorophenol (2.69). ...................................................................................................................................... Table B.1 lists the former MISA outlets that allegedly discharge storm water from the site into the Canagagigue Creek. Of course the entire site remains grossly contaminated such that both surface rainfall over bare ground picks up contaminants as well as the Storm Water Sewer (SWS) in the vicinity of storm water pond (RPW-8). Results from SWS include 2,4-D at 26 ppb, Aniline at 348 ppb, Carboxin at 317 ppb, Diphenylamine at 1.21 ppb and Toluene at 2.11 ppb. .................................................................................................... Table C.2 gives the results of surface water in the Canagagigue Creek, both upstream of Uniroyal/Lanxess as well as downstream. Somewhat unexpectedly the Arithmetic Mean for m/p cresol and o-cresol are both higher upstream at SS-110 than downstream at SS+925. Similarly Nitrosomorpholine has a slightly higher concentration (Arithmetic Mean) upstream (SS-110) than the downstream result. Chlorobenzene, Trichloroethylene, m,p xylenes and Benzene all follow suit. More expectedly the following chemicals have Arithmetic Means higher downstream than upstream namely NDMA and Toluene. Something is very wrong here. Either GHD have messed up and reversed the upstream and downstream positions or there is a source(s) upstream of some of these contaminants. One likely source is the Bolender Park Landfill. Perhaps there is yet another industrial source upstream that has been kept hidden from the public as well as TAG (Technical Advisory Group) in order for Uniroyal/Lanxess to be able to once again minimize the extent of their contamination by hiding behind other sources. ...................................................................................................... Non Aqueous Phase Liquid (NAPL) in Attachment F refers to the LNAPL or Light Non Aqueous Phase Liquid which is comprised mostly of Toluene which was discharged from Building 15 in Uniroyal/Lanxess's south-west corner. It was first made public around 1995 and was allegedly not mentioned earlier upon the advice of Uniroyal's lawyers. Nice. The thickness of the Toluene floating on top of the water Table (UA1) has been dramatically reduced since about 2018. Presumably this is a result of some sort of trench and skimmer as well as by the operation of the UACTS or Upper Aquifer Containment & Treatment System. Nevertheless you should ask yourselves why it took that long to get the LNAPL (Toluene) out of the natural environment. ....................................................................................................... All in all I suggest that decisions made in private in the early 1990s have negatively impacted both the health of the local environment as well as the health of local residents. Much shame belongs to both Woolwich Township and the Ontario Ministry of Environment (MOE/MECP).
