TWO BOREHOLE LOGS NEAR THE SOUTH WELLFIELD



Again this information has come from a flash drive distributed by Conestoga Rovers on behalf of their client Chemtura, prior to Christmas. Two more borehole logs have caught my interest namely the ones for OW163-35 and for OW161. The latter is located in the south end of Elmira right beside the former south wellfield which is located beside Voisin Motors on Arthur St. The second is several hundred yards due east from there and can be seen when walking on the trail beside the bush in that area.

I am certain I have seen groundwater monitoring from OW163 in the past and as expected my recollection is that it was clean. This makes sense based upon it's distance from known contamination as well as the fact that it is screened in a very deep aquifer. Much to my surprise however there are PID (photoionization detector) readings which indicate shallow contamination with volatile chemicals. Although there is a corn field right beside this well I am still surprised if that is the cause of these low level readings.

Of greater concern to me is the results from OW161. Here we have only slightly higher readings than at OW163 but instead of being shallow, they are from 38 metres below ground surface to over 50 metres below. Keep in mind this well is beside the former south wellfield and these readings were taken just over eight years ago (2004). What the hell is going on here? We were told way back in 1990 by one of the consultants working on the Elmira water crisis that it had to be a local, nearby source to the south wellfield causing the massive NDMA contamination. Next thing we hear is that Uniroyal Chemical, nearly a mile away is the source. Orange stains and odours over 40 metres below ground at OW161, fifteen years after the wells were shutdown and many years after off-site pumping began is extremely weird. There are yet other sources which we the public have not been told about.
