CHEMTURA NOVEMBER PROGRESS REPORT IS IN
This month it was hand delivered (by courier) on Dec. 20/10. Many months it's on the fifteenth or sixteenth. The timing of it is a good reason for CEPAC (CPAC) meetings to be at the end of the month in order to give the members time to read and understand the latest technical data.
For many months I've been indicating much improved groundwater pumping both on-site (Chemtura) and off-site (Elmira). Well the bubble has burst. Based on nearly nineteen years of pumping, the aberration is not the poor off-site pumping in November, the aberration is still the good pumping rates for the rest of 2010.
Table A.3 shows us the quantity and quality of on-site groundwater both in the Upper Aquifer and the deeper Municipal Aquifer. It is no surprise to have the following list of toxic chemicals constantly leaching into the groundwater namely: Chlorobenzene, Toluene, Carboxin,Morpholine, MBT, Chlorophenols, NDMA and NDPA.
Appendix B gives us partial results for the MISA discharge points into the Canagagigue Creek. I say partial because allegedly there was no discharge for MISA 0400. I find this very peculiar. Nevertheless some of the usual and normal chemicals discharging into the creek include Carboxin, Aniline, Benzothiazole, MBT and Lindane.
Appendix C measures chemical levels upstream in the Canagagigue and compares them to downstream (from Chemtura) levels. CRA the consultants for Chemtura use a mathematical method to allegedly determine if there is a statistical difference . Me, I just look at the number downstream and if it's higher than upstream such as NDMA, Ethylbenzene, BEHP and Toluene are then I report it here.
Table D.1 in Appendix D lists detections for Dioxins and Furans in Chemtura's on-site groundwater. Not surprisingly they are there despite years of denials, qualifications and claims that Dioxins and Furans adhere to soil particles and don't dissolve into groundwater.
Appendix E has some very good maps of Elmira showing partial plumes of NDMA and Chlorobenzene. Overall it is fair to say that nineteen years of pump and treat with minimal source removal has sucessfully spread these and other contaminants far and wide. Twenty years ago we were assurred that the damage to the Municipal Lower Aquifer was minor and that the Bedrock Aquifer was unaffected. These maps put the lie to those claims.
Finally Table E.1 has a remarkable result for Conductivity. Normal uncontaminated groundwater usually has Conductivities below 900 umhos/cm. Contaminated water often will have numbers from 1200 to 2000 umhos/cm. Well Ch87-A is located SW of former Varnicolor Chemicals Lot 91. It's Conductivity reading is 3400 umhos/cm. Further investigation is required.
In summation the non-cleanup continues at a good pace with on-site leakage into all aquifers and surface water bodies continuing unabated. Eventually (several hundred years???) this site will be restored after all it's contaminants have leaked and flowed downstream into the Grand River and Lake Erie.
