CHEMTURA CANADA PROGRESS REPORT FOR JANUARY 2016

The good news in this report is that they have managed to pump all their on and off-site wells at their target pumping rates for the entire month. If they had managed to do that for the past twenty-four years they wouldn't be years behind their own inadequate pumping schedules.

Table A.3 gives us concentrations of various contaminants in the groundwater at two different Upper Aquifer(UA) containment wells. These contaminants include Chlorobenzene, Toluene, 2-MBT, Aniline, Carboxin, 2,4-Diclorophenol and 2-Chlorophenol. All but the last two are in the thousands of parts per billion. This is gross groundwater contamination.

Table A.4 lists the groundwater contaminants in the off-site pumping wells and also includes the usual suspects. Of note are the NDMA concentrations still in the Elmira Aquifers including 1.99 ppb at W3, 11.6 at W5A and .23 at W5B. The drinking water standard needed to be achieved is .009 ppb.

Table A.5 lists contaminants found in the groundwater at seven different Upper Aquifer containment wells. The list of compounds is similar to Table A.3 but simply shows that the contamination is spread throughout the length of the Upper Aquifer in Chemtura's south-west quadrant.

Appendix B lists the MISA (municipal industrial strategy for abatement) outlets from the site discharging into the Canagagigue Creek. First off one of the historically bad offenders is AWOL. Where did MISA 0400 go? No mention as to why it is suddenly not being examined and published in this Progress Report. Trends in MISA 200, 800 and 1100 are nothing to write home about. The MISA SWS outlet however seems to be showing more decreasing trends in discharges of Aniline, Carboxin and Lindane. It's long overdue and these MISA storm and cooling water outlets have long indicated contaminated groundwater infiltration into them despite claims to the contrary.

Table C.2 as usual is showing that bis (2-ethyl hexyl) phthalate is higher entering the Chemtura property than leaving it. This is unusual. Toluene on the other hand is statistically still higher leaving the site than what it is entering it at the upriver end (North) of the site.

Due west of the site is a new pumping well which is supposed to be starting up this year. It has some truly horrid NDMA concentrations. Pumping tests were conducted last December for W9 and the results from one hour to twenty-two hour pumping tests vary from 53 parts per billion (ppb) to 100 parts per billion. Keep in mind that the drinking water standard for NDMA is .009 ppb.. While of course other compounds were also found it is these terrible NDMA results in Table D.1, decades after both on and off-site pumping have been ongoing, that made it obvious that Chemtura/CRA's original "cleanup" plans were doomed to fail. Both greater pumping AND on and off-site SOURCE REMOVAL are still required but even then time is fast running out.
