Subject: TCE & Barrie's Lake 

Hello Everyone

I was checking out the Lake Erie Source Water protection reports and found an interesting map showing how TCE and Road Salt issues have already been confirmed to the EAST of Barrie's Lake. See the attachments for a photo taken from the report. It is located just to the east where Roseville Road dips down just prior to the green zone. That is in close proximity to where Barrie's Lake is located. 

TCE otherwise known as trichloroethylene is a known carcinogen identified in the groundwater at the location but the delineation of it could change depending on surface and groundwater influences such as the installation of wells, high precipitation/flood events, the movement of water from one watershed to another either above or below ground etc. 

Has the appropriate testing taken place to negate the presence of this chemical in proximity to the new housing projects proposed for the area? If so where is that data?  How old is it and does it reflect delta water levels of spring thaw or is it based on a drought year in November? (no no joke with that statement. Many reports I've reviewed negate spring thaw water levels.)

What is the average depth of the bore holes used to assess the risk and is it reasonable?

I am also concerned that dewatering during construction could draw contaminates towards pristine areas around Barrie's Lake.  Topography cannot reasonably prevent the risks of drawdown contamination issues. Being upstream doesn't matter either. I have included two illustrations in the attachments to illustrate the concerns based on studies conducted by Mike Stone in Waterloo Region. 

In light of the existing TCE/Chloride contamination issues, it would seem reasonable to put a prohibition on the use of new wells in the area to prevent the spread of these known contaminates. If the chemicals end up in Barrie's Lake we could see higher incidents of related human exposures as the toxins go airborn upwind from the proposed development area. In light of the concern I have the following questions: 

Are their wells or dewatering required for the proposed construction activites? 

Will the projected cone of depression from wells/dewatering move TCE/Chloride issues to areas outside of the current delineation zone as seen in the Source Water Protection Map?

Will water quality be monitored before, during and after to monitor for the presence of TCE in Barries Lake, Devil's Creek and the construction zone areas and down stream?

It would seen reasonable to put a prohibition on the use of new wells in the area to prevent the spread of these known contamination issues. Well systems that can pose a risk include residential wells, dewatering wells, wells required for industrial or aggregate operations etc. We need to start looking at these issues not only in regards to this particular project but in areas such as Elmira. Wherever the contamination is, we must work to isolate it to prevent liability risks.  There is bioremediation available to address TCE contamination in situ.

Dilution is not the solution to all pollution. Sometimes it acts as a vector to make a situation far worse. The smaller the enzyme, the more toxic it is so don't spread it. 

There are those who can profit from the destruction of our water supplies so they can replace it. They will say whatever it takes for the sake of approval but in the end, they sign off. They are not liable but Municipalities are. I have attached a report about that. 



As a taxpayer of the Region the last thing I want to see is the Region allowing development activities that could result in very large liablity risk. 

Thank you kindly for your time.
