HOPE SPRINGS ETERNAL - REVIVING MEDIA INTEREST?

I sent an e-mail on to the Waterloo Region Record in regards to the small error regarding NDMA concentrations in the Elmira Aquifers that I described here in the Advocate yesterday. Basically I provided them with the title, author, date etc. of a 1991 report which indicated that groundwater concentrations in the Elmira Aquifers, whether on or off the Uniroyal site were much, much higher than 1,200 -2,900 parts per trillion quoted in the Record. While on-site (i.e. Uniroyal) NDMA concentrations actually are in the thousands of parts per BILLION (ppb) the Record article had quoted 1,200 to 2,900 parts per Trillion (ppt). Now parts per trillion are actually a thousand times smaller than parts per billion. Therefore 1,200 ppt equals 1.2 ppb and 2,900 ppt equals 2.9 ppb. Hence when you have even a lowly 40 ppb found at the private well in 1990 of Harry Soehner on Arthur St. not too far from the south wellfield (E7/E9); that concentration equals 40,000 parts per trillion (ppt) of NDMA which currently has an Ontario Drinking Water Standard of 9 ppt. ........................................................................................................ I have been reading with interest for some time now the environmental stories in the Record authored by Leah Gerber. They have covered a multitude of issues including gravel pits and salt in our regional drinking water aquifers. While right now the public's focus is undoubtedly on Covid-19 AND the U.S. federal election, I am hoping that the public have not forgotten climate change and all its' accompanying issues. Whether droughts or flooding, good quality drinking water will only become more scarce over time. That includes right here in Waterloo Region where it is impacted by industrial practices, road salting and pesticide application.
