CHEMTURA PROGRESS REPORT- OCTOBER 2010

I received this report last week and has been the case recently, on the face of it, things appear well. Both the on and off site pumping rates were maintained for the month of October. Two concessions given to Chemtura by the M.O.E. and agreed to by CPAC are mentioned in the first couple of pages. Both the Upper Aquifer (UA) and Municipal Aquifer (MU) groundwater elevation readings have been reduced in frequency. For the UA instead of taking these measurements to ensure hydraulic containment in October, they will be done in December instead. Similarily the MU readings which used to be monthly are now quarterly. The advantages to Chemtura are obvious in that they are saving money up front and in the long run this assists their long term goal of slow leakage of their contaminants from the site into the natural environment. Afterall, the more that leaks away, the less they eventually have to remove come crunch time.
In regards to Groundwater Collection and Treatment, apparently all parameters except Formaldehyde and NDMA met their effluent objectives. I see no repercussions arising from these discharge failures. In regards to surface water onsite discharge referred to as SWS on the south-west corner of the property both Lindane and NDPA were detected in the discharge. This is not at all unusual as this discharge to the creek as well as the others usually pick up some contaminants from the soil and groundwater on site.

As usual there is little or no mention of source removal that has been ordered by the M.O.E., with the focus being on hydraulic containment .
