This is not a huge step for the evolutionary science I'm afraid: This most likely evolved from life not able to cope with arsenic. It's like when animals couldn't handle the UV-rays and got cancer because of it. Now we're more resistant to it, and we don't die if we walk outside.
I still don't see how. Okay, so now we have a type of bacteria that can eat arsenic. so far it's the only kind like it known, and my point still stands that even IF it were to be used to clean a lake it'd serve NO purpose if that lake has no arsenic. There are already DOZENS of other types of bacteria that have either been made by nature or engineered by man to absorb chemicals and such. If a lake has NO arsenic in it it'd be a waste to use this specific bacteria as there are DOZENS of other kinds that can be used.
If you have a multi-tool that can do the job of a screwdriver, bottle opener, and knife, why not use the multi-tool and not something specific? Yeah, weak-ish comparison, but why use something that can eat arsenic if there is no arsenic to be eaten?
