Last Saturday I had asked a number of questions regarding whether or not indoor air testing had been done yet on homes in the area of Hayes, Kingsmill, Menzies, Audrey and Lawrence Ave. I am disappointed to advise that as per information of, at the very least a dubious nature, the Guelph Mercury reported four years ago that a grand total of TEN homes would have indoor air testing offered to them . These ten homes were in locations allegedly closest to the outdoor soil gas vapour probes with readings of 250 micrograms per litre (and presumably higher??). Very, very strange considering that the criteria or Soil Vapour Screening Level (SVSL) for TCE is only 13.6 micrograms per cubic metre (ug/m3)
This is indeed even more serious scoping/minimizing of a very serious problem with the clear intent to limit the potential disaster that may have occurred and be occurring in this neighbourhood. I mentioned Saturday about the focus for sampling on Menzies, Audrey and Lawrence Ave. as well as a laneway between Lawrence Ave. and Victoria Rd. Between zero sampling of so many streets and homes in the TCE (trichloroethylene) affected areas combined with all of one gas probe sample once on Hayes Ave., our authorities have likely reduced the affected areas by more than 50%.
This is not in the public interest. It is however in both the City of Guelph's interest as well as the Ministry of Environment's. Basically through deception and lying they are telling the public that this isn't a health disaster for many citizens it is merely a minor inconvenience for a few who may have slipped between the cracks .
This article in the April 6, 2020 Guelph Mercury falsely states that 900 ug/m3 was the highest level found of TCE. In fact it was 2,520 ug/m3. The article also states that "...any health effects from TCE in the area were unlikely, and the risk of any vapour intrusion into any homes was low." The reporter advised that these two opinions came from the Ministry of Environment (MECP) and the Wellington-Dufferin-Guelph Public Health. Those are outrageous, wishful thinking, likely bulls*&^ statements given before any indoor testing has been done and before there is any determination of the integrity, lack of cracks or unsealed openings in the foundations of homes throughout the neighbourhood. This is an older neighbourhood and utilities entering homes through the basements are possible vapour entry points as well as minor cracks in foundation walls and floors.
