Luisa D'Amato's Opinion column today is titled "Region reveals the purpose of pumping water from Wilmot Centre wellfields". Well in fact I would suggest that what the Region have done is not so much revealed anything as much as their own stubbornness. At least one local citizen, Samantha Lernout, may have expressed doubts as well when she said "You don't run an experiment and not tell people". If seven years of pumping water from Wilmot to Kitchener-Waterloo is merely a test then I wonder what the last many decades of pumping groundwater from the Waterloo Moraine should be referred to .
I would also like to see the Region offer copies of these alleged hydrogeological reports claiming lots of available water in the Wilmot Centre wellfield to both individuals and citizen groups. It is conceivable that there is plenty of water at the same time as some residents' and businesses' wells are running dry. Factors include the depth of the wells running dry as well as their proximity to regional pumping wells. A high volume pumping well does produce a large cone of influence whereby water levels within half a mile or so of these wells can be seriously lowered while the rest of the aquifer water levels remain as high as ever. Another term for the resulting cone of influence is drawdown. Again a high volume pumping well can seriously lower nearby water elevations by several metres while having minimal effect or no effect on wells one or two miles away.
