Have I got the name correct? Was it the O'Connor Commission which looked into the Walkerton mass bacteria poisoning with E. Coli back around 2000? Among a number of key recommendations was the multi barrier approach to water protection. The plan was to isolate and protect each and every step of water withdrawal, water treatment, water storage, water distribution from its' source to your kitchen sink. This is where the Region of Waterloo have failed horribly. They may claim to have the finest, most up to date water treatment available but that is merely one step in a multi step process. Hence a single breakdown whether mechanical, electrical or human failure at a treatment plant could be catastrophic. Now in Walkerton there were multiple failures mostly human albeit they affected the raw water entering the system as well as the treatment efforts further along as human beings actually fudged some of the treatment data and reports to make things look better on paper than they were.
Here in Waterloo Region we have serious issues with at least two of the four steps mentioned earlier. Water withdrawal from contaminated aquifers is far worse than problematic. Water distribution is also a problem as far too many water pipes still in the ground are made of lead and possibly even some asbestos pipe is still in existence. Some of these pipes astoundingly include ones going to our public and elementary schools. The third step overall namely treatment might be reasonably good but it fails to totally remove trichloroethylene (TCE), glyphosate (Round Up) and others from the treated water sent to our homes and businesses. The Middleton Wellfield in Cambridge even has greater treatment (Advanced Oxidation Process) than all the other groundwater sources but still can't eliminate it completely from the water supply. Similar issues but with less treatment occur at the William St. Wellfield in Waterloo as well as the Parkway Wellfield in Kitchener.
There are also issues, mostly totally ignored, with synergy between toxic contaminants. It is what we don't know that can hurt us. If TCE is at 2 parts per billion (ppb) in our tap water and glyphosate is at 6 ppb plus a dash of lead from the pipes as well then what is the true health criteria? Nobody knows!! Science is wonderful but to date there have been no published drinking water standards for more than one contaminant at a time in our water.
Following is a partial list of known contaminants throughout Waterloo Region groundwater and drinking water wells: NDMA, chlorobenzene, ammonia, TCE, nitrates, glyphosate, xylenes, toluene, benzene, sodium, chlorides and more. Most groundwater has multiple contaminants. Surface water drinking sources (Grand River) have more bacteria, viruses and pathogens such as coliforms, E.Coli, cryptosporidium and many others.
There are expensive fixes such as reverse osmosis systems and ultraviolet light systems that can be put in homes and or much less expensive and maybe much less efficient systems including Brita filters (activated carbon filters). Regardless demanding safer and cleaner drinking water from our elected representatives is the first step. It may even be necessary to delay other hobby priorities of our politicians if we as citizens believe that drinking water for ourselves and families is a bigger priority.
