Bruce DGR Myths - Liquid Drain cleaner is good
Dull this morning, so time to pick on the DGR! Today's myth is the age-old 'Liquid Drano is Good' in underground openings.
This is taken from the DGR scanty annual report. I've been fighting this one for 30 years. Basically, the deeper groundwater at Bruce is Liquid Drano (tm), in that it is very saline and alkaline. This has been taken as a 'good thing', since it means the water has been stagnant for a very long time.
A stagnant pond will not remain so if you breach it. So too, the stagnant, poisonous water of Bruce will not stay there if you drive a big sucker tunnel though it! It's all coming out!
Even if you fill the whole shebang with grout (which they never mention), this water acts on the tunnel liner, and rock bolt support, as well as the storage containers. This water is amazing! If you put it on aluminum, it fizzes up like an Alka-selzter. I wouldn't want any of it to drip on my beautiful hair!
This project will go ahead, no matter what. It will be very interesting to watch it!
The other extreme is Darlington or Wesleyville, where there wouldn't be a speck of water.
