The good news is that all the pumping wells achieved their targeted pumping rates in April, both on and off-site wells. The bad news is that four years after CPAC in conjunction with a consultant (Dr. Gail Krantzberg) publicly advised that Chemtura and the M.O.E. would not achieve their 2028 cleanup deadline with their current plans and three and a half years after which they agreed with that; they still are "in process" with higher pumping rates and In Situ Chemical Oxidation. In other words their target pumping rates are essentially unchanged. Yes they have raised pumping rates in some wells but also lowered others. We are still awaiting the so called doubling of the pumping volumes. In November 2012 we were promised a tripling of the rates. We also haven't seen to date any biological modeling to indicate if there will be effects on life within the creek after a doubling or more of the treated discharge to the creek.

The influent concentrations of organic chemicals to the treatment systems both on and off the Chemtura site remain at very high levels. Toluene on site is repeatedly in the thousands of parts per billion primarily due to unremoved free phase Toluene (LNAPL). NDMA concentrations remain thousands of times higher than drinking water standards in places both on and off site. There is a very, very long ways to go with only twelve years remaining in the deadline.

MISA (Municipal Industrial Strategy for Abatement) indicate very low levels of Lindane and Toluene are still being discharged to the Canagagigue Creek from Chemtura.

The surface water sampling of the creek indicate exceedances with Formaldehyde and Iron. Allegedly even the Formaldehyde is not a result of chemical contamination by Chemtura although I am skeptical. Furthermore ethylhexylphthalate and Toluene still show up in the long term averages slightly different upstrem than downstream. As expected Toluene is higher downstream courtesy of Chemtura whereas the phthalate is higher upstream indicating another source above Chemtura on the creek.

While these monthly Progress Reports are not a total waste of time nevertheless they continue to be primarily propaganda pieces for Chemtura and the Ontario Ministry of the Environment (M.O.E.).
