No, not that chemical directly added in water, but chlorine instead, that results from chlorine additoin.

! Q. d j6 ]/ y' g4 L. `我没有怀疑EDMONTON水质不达标,从水厂出来的水水质肯定是达标的。我原来在一个污水处理厂干过几年,即便是污水如果达不到水质标准,我们也不敢注入到地下(增压,驱油),何况是饮用水,水质是不用怀疑的。 ...

Yes, you can drink from the tap directly. But we do NOT have the best quality of water in Edmonton considering where the water intake is placed.
