OCTOBER 2015 CHEMTURA MONTHLY PROGRESS REPORT



The off-site pumping rates are where they have been for quite a while now and where they should have been and weren't for about a decade. Above and beyond Chemtura's basic plan for off-site remediation being faulty was the fact that they simply didn't even follow their own plan for so long. The list of excuses why not is longer than my arm. Of course the alleged tripling (now doubling) of those same rates has yet to begin. Well E7 continued to pump during October but it is scheduled to shut down soon.

The influent concentration of NDMA to E7 during October was .096 parts per billion or 96 parts per trillion. While that is very low it is still approximately ten times higher than the drinking water standard of 9 ppt. (parts per trillion). I'm not so sure that shutting down this mainstay of the off-site pumping regieme is such a good idea.

We the public are still waiting for the results of the "East Side Surficial Soil and Groundwater Investigation Plan". Allegedly the results will be honest and allegedly they are coming in a final report on the investigation.

Table A.1 has some interesting results for NDMA and some non results for Toluene. NDMA is still ridiculously high at W3 and W5A, both off-sitre pumping wells. Toluene results are missing except for 200 ppb. at the Primary Influent point in the treatment system. It would be appropriate to know which wells are producing which concentrations.

Table A.3 has some bizarre numbers for Toluene. While the influent at some of the Upper Aquifer wells is around 7000-8000 ppb. it is the effluent results which are weird as they are essentially the same . That makes no sense.

Appendix B is the MISA results or Municipal Industrial Strategy for Abatement. What a joke. The longterm Trend Analysis tells the tale. Most of the chemicals in the alleged surface water being discharged into the creek through these pipes have no trend up or down. A few are decreasing and a couple are increasing. Clearly groundwater continues to infiltrate these pipes and discharges to the Canagagigue Creek.

Regarding Table C.2 a particular pthalate (BEHP) continues to enter the Chemtura property from upstream. I am unaware of any attempts by the M.O.E. to determine its' source. Toluene still has a slightly higher downstream concentration than upstream indicating leakage into the "Gig" from the Chemtura property.

Table D.1 indicates no surprise in that DNAPL chemicals are still to be found at high groundwater concentrations in Chemtura's south-west corner, exactly where they've always been. MBT, Carboxin and aniline seem to be leading the way in this Table.

Finally Table E.1 gives the monitoring results of well OW60, northwest of Chemtura. NDMA results even after longterm pumping tests are a ridiculous 20 parts per billion (ppb.) with a drinking water standard of .009 ppb.. Supposedly testing for ISCO (chemical oxidation) will begin soon. It was allegedly tested for on the Yara (Nutrite) property unsucessfully some time ago. Could NDMA be slowly dissolving from a NAPL source?

This folks is your "Progress Report" for October.
