Bubblers can start bubbling again

You may have been going on a stroll through a park during a recent 80-degree day, wiping sweat from your brow and craving just a drop or two from that water fountain you spotted out of the corner of your eye. But upon closer inspection, black garbage bags and ominous signs about untreated water would keep the H₂O from your lips.

Now, you can feel free to once again go on that 5-mile jog without lugging around a backpack full of Perrier.
