TCE AND DRINKING WELLS NEAR NORTHSTAR & BISHOP ST.

A report was written in December 2006 examining the Dumphries Conservation Area (near Northstar Aerospace) and municipal well P6. The report gave information in regards to a Sentry well which was installed near well P6. "On the basis of the findings of the April 2006 investigation, AMEC recommended that the Sentry Well be installed near existing well nest MW267 (Upper Aquifer)/ MW272 (Shallow Bedrock)."

During 2006 and probably earlier, low levels of TCE and 1,1,1 TCA had been found in both the Upper Aquifer and the Shallow Bedrock nearby. This is absolutely to be expected under the circumstances of the massive groundwater contamination found just north along and downgradient of Bishop St.. The Region of Waterloo apparently on a routine basis pump drinking wells using "well management" practices. This concerns me as it could be interpreted as playing musical wells. In other words stop pumping a particular well when you've drawn nearby contaminants into it, "rest" it for a few months or more until the cone of influence has dissipated and then go back to pumping it again. I don't care whether they have Ministry of the Environment approval or not; they do not have citizen approval for any such practices with our drinking water.
