DNAPL DNAPL DNAPL
"DNAPL (also D-NAPL) is an acronym for Dense Non-Aqueous Phase Liquid and describes a liquid (which may contain more than one compound) which has a specific gravity greater than 1.0, forms a separate phase in water and whose solubility in water is not infinite."
The specific gravity greater than one means that it is heavier than water and thus unlike oils, DNAPLS sink through surface and groundwater until they find a less permeable surface to rest upon.
The various Control Orders and Amending Orders issued by the Ontario Ministry of the Environment upon Uniroyal Chemical (Chemtura) all state that DNAPL must be eliminated as a contaminant source by December 31, 1992. This has not happened although there has been a deluge of technical reports by Chemtura's consultants constantly minimizing the presence and environmental effect of DNAPLS. These reports in my opinion share a common trait and that is that the technical data including groundwater monitoring all support the knowledge and understanding that Free Phase DNAPL exists in the subsurface in the former operating ponds namely RPW5, 6, 7, 8. These reports also generally come to conclusions and reccommendations which are counter to their own data. Two of the more recent publicly distributed reports are the August 2007 and April 18, 2007 reports. As per the allegedly legally binding Control Orders, until DNAPLS are removed as a contaminant source they will continue to contaminate our drinking water aquifers. This issue and the way it's been handled in private meetings with Chemtura, by CPAC over a period of many years, was the final straw in my complete break with the old CPAC. Even after I was initially given the boot by the old Woolwich Council from CPAC, I could not bring myself to believe that CPAC were co-opted. Hard critical reflection, including self criticism for blind loyalty has opened my eyes to the obvious. The old CPAC have long failed the DUCK TEST. If it quacks like a duck, if it waddles like a duck and if it looks like a duck, then it probably is a duck. Both the DNAPL failure and CPAC's ongoing approval of neverending phoney "investigations" around it, combined with CPAC's refusal to honestly communicate publicly as to what they are doing about it, have convinced me. Some of them are co-opted and have been so for years.
