THE SEPTEMBER 2019 PROGRESS REPORT

Well the obvious first. Pumping well W9 is still in the crapper. At least that is, the monthly pumping average was 3.4 litres per second while the Target Average was supposed to be 13.6 litres per second. The grand total pumping rate for all off-site wells was 68.5 l/sec which is excellent when compared to the last twenty-one years of off-site pumping. It is however pathetic when compared to the promises CPAC was given in November 2012 regarding what CRA and Chemtura felt was necessary to achieve the 2028 cleanup deadline.

On-site pumping well PW5 is also still below its Target pumping rate. This is a bad combination of pumping higher off-site and lesser on-site. This is exactly how on-site hydraulic containment can be lost resulting in heavily contaminated groundwater moving off-site.

For those not easily manipulated and fooled it has become increasingly obvious over the last thirty years that Uniroyal Chemical managed to grossly pollute private and public property to their west, east, south, and quite frankly as well north into Bolender Park whether from their own property or from disposing of their industrial wastes into the former Bolender Landfill.

Figure D.3 in Appendix D shows us exactly how little hydraulic containment there is for half the monitoring pairs in Lanxess's south-west corner. These pairs are comparing shallow groundwater levels in this corner with the elevation of corresponding surface water in the Creek ("Gig"). Two of the pairs have just over .2 metre difference in elevation and one pair has only a difference of less than .1 metre. As per the MOE's hydrogeologist (Cynthia Doughty) these water elevation differences are not adequate toi ensure that the shallow aquifer on the Lanxess site is not discharging into the Canagagigue Creek.

Appendix E shows us graphs of various key groundwater wells and far too many of these off-site wells continue to have concentrations of either/both NDMA and chlorobenzene above the Ontario drinking water standards. These include OW165-17 (NDMA above), CH-89B (NDMA above), CH-47E (both above) and CH-56B (both above). The first three are to the immediate west of Lanxess and the last is southwards near Union and First St.

Appendix F relates to NAPL monitoring near Building 15 on-site. This is the location of a massive leak (over time) that resulted in between 10,000 and 40,000 gallons of toluene floating on the water table. The thickness of this free product has generally diminished slowly over time although as recently as December 2017 it appears to heve been measured at MW13-07 at a thickness of .29 metres floating on the water table. That is still horrendous.

Appendix G also relates other various off-site monitoring results for NDMA and chlorobenzene. CH-68A has chlorobenzene at 210 parts per billion (ppb) and CH-70D has it at 380 ppb. The groundwater standard is 80 ppb. NDMA is measured at 22.2 ppb at OW-88B (R) and at OW58-24 at 32.59 ppb. This well while allegedly off-site I believe is right on Lanxess's western boundary. The criteria for NDMA in groundwater is .009 ppb. The prizewinner for off-site NDMA appears to be )W61-34 at 195 ppb. These are truly outrageous concentrations of toxic chemicals still off-site.

Appendix H reminds us of the extreme chlorobenzene contamination still on-site due to the presence of both free phase and residual DNAPLS (dense non aqueous phase liquids). There is 19,000 ppb chlorobenzene in the groundwater at OW88-19. This is all part and parcel of the decades old DNAPL coverup which was enabled by the company, their consultants, the Ontario MOE and as well by a couple of local citizens seeking status and approval by local authority figures.
