I really found some interesting stuff in the June "Progress Report". Overall on and off-site pumping (hydraulic containment) was excellent with one off-site well failing to meet its' target pumping rate. Well W4 by the water tower and behind (west) the old Varnicolor site averaged only 9.0 litres per second versus its' target of 11.4 due to repairs being necessary.

NDMA was again detected in the Canagagigue Creek although below the Provincial Water Quality Guidelines. The point is that this is more evidence that the site continues to leak and discharge off-site despite Chemtura/M.O.E. claims to the contrary. Nitrosomorpholine (NMOR) also still has a higher arithmetic mean concentration downstream than upstream. This also indicates past and probably ongoing leakage. To add to the mix, Lindane (insecticide) is also still leaching from the Chemtura site and being discharged via one of the MISA (municipal industrial strategy for abatement) outlets.

Table A.3 indicates some very high concentrations of DNAPL chemicals in the Upper aquifer pumping wells on site. These chemicals are MBT, benzothiazole (BT), carboxin and aniline.

Both Table D.2 and Figure D.3 do not give confidence in the alleged hydraulic containment of the shallow aquifer (UA) at Chemtura. The difference in groundwater elevations versus creek elevations at some locations is 3/4 of a metre. That is extremely impressive hydraulic containment. Another location however has an elevation difference of less than half an inch and despite reassurances from Chemtura in the past, I'm not buying it. That is NOT reliable hydraulic containment and I don't care how many times a day Chemtura are "monitoring" it.

Attachment G has tables of soil samples taken at 11 Queen St. in Elmira. These soil samples show concentrations of NDMA in the soil at ridiculous levels and this is more than seventy-five feet below the ground's surface. Chemtura when you do a job on an aquifer you really do a job.

Last but not least Figures E4 & E5 plus Tables E1 & E2 give us the groundwater concentrations of NDMA and Chlorobenzene in wells CH47 and Ch56. The first well is just west off-site of Chemtura on the former Yara (Nutrite) property and the other is on the south border between Chemtura and the Elmira Sewage Treatment Plant. CH47's concentrations of both NDMA and Chlorobenzene are above the Provincial drinking water standards. CH56's concentrations are above for NDMA and merely substantial for Chlorobenzene. Once again this is evidence of either ongoing leakage from the Chemtura site or evidence of off-site sources at Yara and the STP. In the case of Yara they are an off-site source of other chemicals however the NDMA and Chlorobenzene are most likely from Chemtura. When the STP was constructed in 1965, buried drums of Uniroyal's chemical wastes were discovered, so it's pretty clear that that current off-site contamination is all courtesy of Uniroyal/Chemtura. Once again this is contrary to the factually ficticious nonsense that Chemtura are selling with support from their partner in pollution, the Ontario Ministry of the Environment.
