I guess if we keep using acesulfame for a few hundred years, eventually all water on the earth will taste sweet.

Yum. Sweet sugary water.

Oh and extreme teratomas in whatever sealife is left.

I live in Cambridge, which is on the Grand River.  We always say flush twice, Brantford needs the water.  Now, maybe I'll add some more sweetener for them too.

Dump plenty of other pesticides in the drinking water, why should this one be any different?

Diet soda is sewage.

Before I start to panic, I want to know a few things: What the actual concentrations detected were, what concentration is needed to taste it, and what concentration would be needed to affect a biological response.

So far, I can only find the first in the publication:

The maximum concentrations that we measured for sucralose (21 µg/L), cyclamate (0.88 µg/L), and saccharin (7.2 µg/L) are the highest reported concentrations of these compounds in surface waters to date anywhere in the world.

So there's that. The authors also point out that waste treatment removes some of the sweeteners better than others, so this isn't an intractable problem. However, before we start suggesting they ban certain sweeteners, I'd point out one other line from the publication:

Relatively little is known about the fate and effects of artificial sweeteners in rivers.

They list a few studies on the matter (which I haven't had time to delve into), but it's not clear that "high" levels of artificial sweeteners actually means anything.

Artificially, even.
