I've been following all the articles, opinion pieces and Letters To The Editor carefully. Overall K-W Record reporters are doing a great job bringing the facts as they know them to the public's attention. The trouble is that the Region have been much less than forthcoming for many decades now hence neither the public, the developers, builders, politicians or the media truly understand the mess we are in. The bottom line is that having read Luisa D'Amato's TWO page article titled "Will we have enough water ?" the answer is an unequivocal no. Luisa among other things advises readers about the steps to increase our water supply both immediately plus over the next four or five years and I find that terrifying.
Why is it terrifying? It is terrifying because the Region clearly are desperate to avoid litigation from developers and builders who have sunk large amounts of time and money into proposed new developments whether they be detached homes, townhouses, condominiums or office buildings. How desperate you ask? They are so desperate they are pardon the pun "Going back to the well" in order to increase their water supply. Some of these "wells" have been shut down for years and in some cases decades. Why were they shut down in the first place, you ask. Because they were CONTAMINATED. This includes trichloeoethylene (TCE) in the Parkway wells (Deilcraft), benzene in the Greenbrook Wellfield (courtesy of Ottawa St. Landfill), multiple solvents and industrial chemicals with PCBs floating in oil (LNAPL) upgradient of the Woolner and Pompeii Wellfields along the Grand River (Breslube). Other problems with these river wells as they are called is odour issues that do not occur in groundwater wells located away from surface water. Speaking of surface water the Middleton Wellfield is in the south end of Cambridge right beside the Grand River. The wells however are screened in the Bedrock Aquifer and likely would be separate from the river water however they are not separate from the free phase (DNAPL) TCE in the fractured bedrock fissures and pores.
Also pumping more water from the Middleton Wellfield which supposedly can be then pumped uphill to Waterloo and Kitchener will likely draw out more dissolved TCE from the Bedrock Aquifers. As it is there is a special and very expensive TCE treatment system called AOP (Advanced Oxidation System). The other allegedly still unresolved problem is the different bacterial disinfection system used at the Middleton Wellfield versus the Mannheim Service Area. My guess is that we are talking a chlorine system versus a chloramine system.
Wilmot Township have been picked to supply water to the Mannheim Service Area almost immediately. That combined with the loss of recharge due to the 700 acre proposed industrial megasite should go over well with Wilmot residents and politicians. Gravel pits, industrial megasites, plus supplying water to K-W should be a fairly explosive mixture for the Region.
So let's summarize. We (developers, builders, politicians) want one million people here by 2050. Do we also want more contaminated water being mixed with what clean water we have left to keep us at least technically below the Ontario Drinking Water Standards (ODWS)? Are we so desperate for growth that we will continue to revive old, shut down contaminated wells to boost our water supply? Meanwhile our river water source (The Grand) will continue receiving increasingly larger loads of treated (hopefully) human sewage as we approach one million people. WHAT POSSIBLY COULD GO WRONG WITH THIS SCENARIO?
