Unless every jurisdiction in the world has facilities to neutralize/combat these chemicals getting through into the taps, wouldnt we all be drinking this stuff right now anyway....... and probably have been for years if not decades?

Water can be treated to remove these chemicals. You can actually go look at concentrations of all sorts of chemicals in Calgary's water supplied from
the Glenmore Water Treatment Plant (south Calgary, from the Elbow River) and
the Bearspaw Water Treatment Plant (north Calgary, from the Bow).
Health Canada guidelines are such that 200 ng/L (0.0002 mg/L) of PFOA is acceptable, and the City doesn't even report levels below 10 ng/L. I would wager they don't report values below that because they can't measure concentrations lower than that; certainly not down to the picogram (0.001 ng, or 0.000000001 mg/L)...
