Super-silly-ous suit
This lawsuit, as cited in ZH, is not only silly but counterproductive. It says that Poland Spring Water is "not spring water" because it comes from a well that contains "groundwater".
Absolutely no difference. Every spring and every aquifer and every well is groundwater. It all comes from rain, filters through soil, reaches a layer where it stops and pools in gravel or rocks.
There's a real difference between well water and river water. River water hasn't been filtered. It contains immediate and fresh bird poop, fish poop, and human poop.
Most city water systems are drawn from wells, which means they're just as "springy" as the imaginary "pure spring".
The only thing that matters is the impurities. Some wells contain minerals that make the water pleasantly tasty and effervescent. Other wells just taste bad. Other wells and aquifers are pretty nearly pure.
By setting up a costly legal precedent on the false distinction of "spring" and "ground", this lawsuit distracts from the
slightly important distinction of tap water vs well water. When bottled water is simply taken from the city system, it's probably cleaner than "pure spring" water, thus you might want to pay more for it... if you're stupid enough to fall for the whole bottling fraud in the first place.
